Iriotec® 8000 for the marking of plastics

Laser-sensitive pigment powders and pigment granules 
Iriotec® 8000 offers you the choice for your permanent and razor-sharp markings: Depending on the polymer and application you can set light or dark markings plus choose between two product groups.

Pigment powders: color change in the polymer
The Iriotec® 8000 Series pigment powders induce a color change in the polymer itself which optionally leaves a light or a dark marking. They impress with exceptional temperature stability and their color neutrality. Therefore they are also suitable for use with different colored plastics – and unfold their effect even in low concentrations.

Pigment granules: laser marking regardless of the polymer
The Iriotec® 8000 Series pigment granules consist of miniscule components. They contain a laser absorber and color former and stay together in the polymer. These particles turn dark under laser light, even at a very low threshold value. The result: a consistent dark marking – regardless of the polymer’s ability for color reaction.

Our Iriotec® 8000 laser pigments  transform the energy of the laser light and via color change, cause a visible and permanent marking: either through a color change in the surrounding polymer or the laser pigment itself. As an expert leader in laser marking, we offer two world-class solutions:
 


The composition of the material is vitally important for an optimal result: a first-class, high-contrast laser marking. The marking comes from either  a combination of the unchanged polymer, carbonized materials (carbonization) or small gas bubbles (foaming).

Easy and versatile application

Laser marking: flexible, permanent and solvent-free
Pigment powders and granules of the Iriotec® 8000 Series open up a wide variety of possibilities to “write” any kind of graphic character, code or image onto all conceivable plastic parts – regardless of their shape and surface structure.

To achieve their full potential in product marking, a few aspects have to be observed with regard to their processing.

Processing of pigment powder

At first, the pigment powder hast to be incorporated into a masterbatch  (= pigment concentrate) or compound . Depending on the application the masterbatch producer will recommend a monobatch (with only this pigment) or a combibatch (in combination with other colorants). It would be best to ask your masterbatch producer for advice.

For a list of selected partners that work with Iriotec® pigments, please go to „specialists“.

Processing of pigment granules

The pigment granules can – in contrast to pigment powder – be added as a monobatch during the relevant production stage and under certain circumstances. However, in most cases we recommend the use of a masterbatch (= pigment concentrate) as  combibatch (in combination with other colorants). This ensures a homogeneous distribution of the pigment particles in the final product. Also the use of a compound formulation is possible. 

For a list of selected partners who already use Iriotec® pigments in their masterbatches, please go to „specialists“.


Due to the stability of the marking laser products of the Iriotec® 8000 Series are suitable for a wide range of applications: 
 
  • Expiration dates on bottle caps: They must meet the most stringent food regulations.
  • Technical parts: Their serial numbers, ID or bar codes must be indestructible and remain permanently visible.
  • Caps and closures: Widely used as information carriers, they require among other things robust, fine-line, high-resolution markings.
  • Liquid containers for the automotive industry: They must be able to withstand chemicals (oil) and heat without labels that could become detached.
  • Containers for diagnostics: With marked lines (e.g. for filling levels) and without labels that could become detached – also for the end user.
  • Cables and wires: To make sure that every installed cable is precisely labled, so that it can be identified in case of a failure, the exact and long-term marking of cables with Iriotec® 8000 is advisable.
  • . . . and many more

Iriotec® 8000 pigment powders and granules are the right choice for high-contrast plastic marks of all types, because they provide – in combination with the right laser beam – a clear and well defined, indestructible mark.

Various methods of plastic marking with laser light (clockwise from top left): ablation, engraving, foaming and color change.

Permanent Marking with the Power of a Laser

Laser marking: flexible, permanent and solvent-free 
The need for laser marking of plastics has increased significantly in recent years, likewise the number of plastic applications. EMD Performance Materials has been working intensively in this area since 1995 and today offers a wide range of possibilities for economical laser marking. 

In laser marking, flexibility, durability and forgoing solvents or time-consuming pretreatments are high priorities. The labeling, coding and marking of plastic with laser light satisfy the highest standards of industrial production in every aspect. 

Depending on the application, there is a choice between two marking methods: 

Carbonization
  • Color change through laser pigments/laser granules that are incorporated into the plastic 
  • Ablation/engraving 
Foaming
The laser beam induces the development of a light marking. The pigment powder absorbs the light and causes the polymer to develop bubbles and form a foam layer.

Gravur and ablation – lacquer removal and engraving:
  • The laser beam removes the material from the surface and leaves an indentation at the desired places.
  • For this process Iriotec® pigments are not necessary.

Acrylnitril-Butadien-Styrole (ABS)

Acrylonitrile butadiene styrene (ABS) develops a dark mark by itself. This can be improved by laser-sensitive additives in terms of marking speed and edge sharpness.

Dark markings:
  • Natural and light colors: Best marking result with 2 - 3 % Iriotec® 8208; good result with 0.3 % Iriotec® 8825 or Iriotec® 8850.
Light markings:
  • Dark colors: Since styrene polymers tend to develop dark markings, it is quite difficult to mark dark colors with a good contrast. Light markings can most of the time be realized only with low marking speed. Recommendation: 0.5 % Iriotec® 8815. If carbon black is part of the formulation, it may be useful to substitute it with Iriotec® 8835 to create a light marking. 
  • Black: 0.5 % Iriotec® 8835 or Iriotec® 8830 with 0.1 % carbon black (to avoid a brownish discoloration of the mark, the amount of carbon black must be significantly limited to < 0.2 %).
 

Acrylic glass/Plexiglas

Polymethylmethacrylate (PMMA), commonly known as acrylic glass or Plexiglas, is highly transparent and tends to develop light markings. Dark markings are difficult to produce, even when adding laser-sensitive additives.

Dark markings:
  • Transparent: We do not offer an appropriate solution to preserve the transparency. Good marking results are obtained with 0.3 % Iriotec® 8825. However this affects transparency.
  • White and light colors: 0.5 % Iriotec® 8850
Light markings:
  • Dark colors: 0.5 % Iriotec® 8815. To make a light marking, frequently laser parameters have to be adjusted: Light markings are achieved with low marking speed. If carbon black is part of the formulation, it may be useful to substitute it with Iriotec® 8835.
  • Black: 0.5 % Iriotec® 8835 or Iriotec® 8830 with 0.1 % carbon black (to avoid a brownish discoloration of the mark, the amount of carbon black must be significantly limited to < 0.2 %).
 

Polycarbonate (PC)

Polycarbonates develop a very dark mark by themselves. They can be significantly improved in terms of marking speed and edge sharpness by laser-sensitive additives.

Dark markings:
  • Transparent: Best results are achieved with 0.1 % Iriotec® 8825 which maintains transparency to the largest extent.
  • White: Best results were achieved with 0.7% Iriotec® 8210. Also 0.3-0.5 % Iriotec® 8841 or Iriotec® 8825 are very well suited for this result.
Light markings:
  • Dark colors: The material tends towards dark markings. It is therefore quite difficult to create dark colors with a good contrast. Recommendation: 0.5 % Iriotec® 8815. To make a light marking, frequently laser parameters have to be adjusted: Light markings are achieved with low marking speed. 
  • Black: 0.5 % Iriotec® 8835 or Iriotec® 8830 with 0,1 % carbon black (to avoid a brownish discoloration of the mark, the amount of carbon black must be significantly limited to < 0.2 %).
 

Polyamides = Nylons (PAs, PAGF)

The polyamides polycaprolactame (PA6), polyamide 6.6 (PA66) and glass fiber-reinforced polyamide (PAGF) mainly demonstrate a foaming reaction under laser light. Therefore, it is quite difficult to produce a good, high-contrast marking.

Dark and light markings:
  • Natural and light colors: Best results can be obtained with 0.3 % Iriotec® 8850. This creates light as well as dark markings. With glass fiber-reinforced materials Iriotec® 8825 is used to avoid negative effects on the mechanical properties. Sometimes a concentration of up to 1 - 2 % may be necessary for a good contrast. 
  • Dark colors: 0.3 % Iriotec® 8825 or 8850. To make a light marking, frequently laser parameters have to be adjusted: Light markings are achieved with low marking speed. If carbon black is part of the formulation, it may be useful to substitute it with Iriotec® 8835 to create a lighter marking.
  • Black: 0.5 % Iriotec® 8835 or Iriotec® 8830 with 0.1 % carbon black (to avoid a brownish discoloration of the mark, the amount of carbon black must be significantly limited to < 0.2 %).
 

Polyolefins (PE and PP)

Polyolefins such as polyethylene (PE) and polypropylene (PP) cannot be marked well under laser light without additives.

Dark markings:
  • Natural and light colors: Best marking results with 0.7 - 1.0 % of the pigment granules  Iriotec® 8210 or 2 - 3 % of Iriotec® 8208; very good marking results in opaque colors with 0.3 % Iriotec® 8850, good marking results with 0.3 % Iriotec® 8825 or 8820.

Light markings:
  • Dark colors: 0.5 % Iriotec® 8815. To make a light marking, frequently laser parameters have to be adjusted: Light markings are achieved with low marking speed. If carbon black is part of the formulation, it may be useful to substitute it with Iriotec® 8835 to create a lighter marking.
  • Black: 0.5 % Iriotec® 8835 or Iriotec® 8830 with 0.1 % carbon black (to avoid a brownish discoloration of the mark, the amount of carbon black must be significantly limited to < 0.2 %).
 

Polystyrene and SAN

Polystyrene (PS), styrene acrylonitrile (SAN) and acrylic ester (ASA) tend to develop an intrinsic dark marking. Laser-sensitive pigments can improve this marking with regard to marking speed and edge sharpness.

Dark markings:
  • Natural and light colors: If the transparent (amorphous) plastics remain uncolored, this must not be disturbed by additives – in general, only Iriotec® 8825 at a concentration of 0.3 percent is used. 
Light markings:
  • Dark colors: Since styrene polymers tend toward dark markings, it is quite difficult to mark dark colors with a good contrast. Recommendation: 0.5 % Iriotec® 8815. To make a light marking, frequently laser parameters have to be adjusted: Light markings are achieved with low marking speed. If carbon black is part of the formulation, it may be useful to substitute it with Iriotec® 8835 to create a lighter marking.
  • Black: 0.5 % Iriotec® 8835 or Iriotec® 8830 with 0.1 % carbon black (to avoid a brownish discoloration of the mark, the amount of carbon black must be significantly limited to < 0.2 %).
 

Polyoxymethylene (POM)

With conventional laser-sensitive additives polyoxymethylene (POM) develops no dark marking. This is possible only by using the granule technology.

Dark markings:
  • Natural and light colors: 0.7 - 1.0 % Iriotec® 8210. Alternatively 3 % Iriotec® 8208.

Light markings:
  • Black: 0.5 % Iriotec® 8835 with 0.1 % carbon black (to avoid a brownish discoloration of the mark, the amount of carbon black must be significantly limited to < 0.2 %).
 

Thermoplastic Elastomers: TPE and TPU

Thermoplastic elastomers (TPE) and thermoplastic polyurethane (TPU) cannot be marked well or do not offer the prospect of a satisfactory marking under laser light without additives.

Dark markings:
  • Natural and light colors: Best marking results with 0.7 - 1.0 % of the pigment granules Iriotec® 8210 or 2 - 3 % of the pigment granules Iriotec® 8208; good marking results with 0.3 % of the pigment powder Iriotec® 8825.

Light markings:
  • Dark colors: 0.3 % Iriotec® 8815. To make a light marking, frequently laser parameters have to be adjusted: Light markings are achieved with low marking speed. If carbon black is part of the formulation, it may be useful to substitute it with Iriotec® 8835 to create a lighter marking. Alternative: We also have obtained good results with 0.5 % Iriotec® 8815.
  • Black: 0.5 % Iriotec® 8835 or Iriotec® 8830 with 0.1 % carbon black (to avoid a brownish discoloration of the mark, the amount of carbon black must be significantly limited to < 0.2 %).
 

Terephthalat Derivates: PBT and PET

Without laser pigments, polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) do not show a good marking.

Dark markings:
  • Natural and light colors: With < 0.3 % Iriotec® 8825 the transparency of PET is maintained to a large extent.
  • Best marking results in opaque colors can be obtained with 0.3 % Iriotec® 8850.

Light markings:
  • Dark colors: 0.3 % Iriotec® 8815. To make a light marking, frequently laser parameters have to be adjusted: Light markings are achieved with low marking speed. If carbon black is part of the formulation, it may be useful to substitute it with Iriotec® 8835 to create a lighter marking.
  • Black: 0.5 % Iriotec® 8835 or Iriotec® 8830 with 0,1 % carbon black (to avoid a brownish discoloration of the mark, the amount of carbon black must be significantly limited to < 0.2 %).
 

Silicones

Due to their elasticity and surface properties it is very difficult to print on silicones. Therefore working with a laser is a very good alternative for marking these materials, because the mark itself is incorporated into the material. Unfortunately silicones cannot be marked with an IR-Laser without additives – laser pigments allow for dark marks. 

Dark marking:
  • Natural and light colors: Dark, high-contrast and fast marking on silicone can be executed with 0.5 to 1% Iriotec® 8850. Color shift can easily be compensated with more colorants.
Light markings:
  • To this no experience has been acquired.
 

Fluoropolymere (PTFE/FEP/PFA)

Fluoropolymers are characterized by their non-sticking-properties. Therefore it is also hard to mark them. Laser pigments by our company enable the permanent and economic marking of fluoropolymers by means of IR laser.

Dark marking:
  • Natural and light colors: The addition of 0.3 % Iriotec® 8825 to the formulation enables a dark or light marking of fluoropolymers. At this point the laser parameters decide upon the color of the mark. Dark marks usually appear at  higher marking speeds. 
Light marking:
  • Dark colors: The addition of 0.3 % Iriotec® 8825 to the formulation enables a high-contras dark or light marking of fluoropolymers. At this point the laser parameters decide upon the color of the mark. Light marks usually appear at lower marking speeds.
 

Thermosetting plastics

Thermosetting plastics (duroplastics) are interconnected polymers, which are no longer shapeable after hardening. Therefore it is important to implement the color change in the laser additive itself. We only offer additives for dark marks.

Dark marking:
  • Natural and light colors: The addition of 0.5 % Iriotec® 8826, 8841 or 8850 to the formulation enables a high-contrast marking of duroplastics towards dark. However, this is not suitable for coating materials (varnishes).
