  • Very lightweight
  • Bondable
  • Printable
  • Good insulation and sound insulation values
  • Chemical- and corrosion-resistant
  • Application areas:
  • Promotional signs
  • Displays
  • POS displays
  • Shelf dividers
  • Casing
  • Vehicle construction
  • Insulations

PA is a macromolecular, partially crystalline thermoplastic with high impact resistance. The combination of hardness and stability on the one hand as well as toughness and tensile strength on the other hand is achieved by no other thermoplastic. Today PA is one of the most used plastics in machine construction. It has good chemical resistance and additionally it is bond- and weldable.

  • Most important properties:
  • High stability, hardness and toughness
  • Machinable, bond- and weldable
  • Chemically resistant against fats, oils, fuel
  • Unreinforced types are electrically isolating
  • Good sliding properties with high wear resistance
  • Application areas:
  • Sealing rings
  • Flanges
  • Connectors


PC (polycarbonate) is an amorphous, high-strength and transparent thermoplastic. It combines many of the good properties of metals, glass and plastics such as impact resistance, transparency, stiffness, dimensional stability and good heat resistance, even at low temperatures. 

  • Most important properties:
  • High stability, hardness and impact resistance
  • Good heat resistance, even at low temperatures
  • Very high dimensional stability
  • Good electrical isolation
  • Bond- and weldable
  • Application areas:
  • Containers
  • Distribution blocks
  • Optical parts


PET is an unreinforced partially crystalline, thermoplastic polyester. It is characterised by a high mechanical stability, excellent dimensional stability (better than POM), very good wear resistance (comparable with PA 6) and very good sliding properties. PET has also good electrical insulating properties and good acid resistance, it is physiologically harmless. A very low water absorption, which hardly affects the mechanical and electrical properties, and the (within the group of the thermoplastics) comparatively low thermal expansion coefficient are the reason for an excellent dimensional accuracy.

  • Most important properties:
  • High stability, hardness and toughness
  • Low thermal expansion, dimensionally stable
  • High acid resistance
  • Good sliding properties and wear resistance
  • Very good electrical insulating properties
  • Bond- and weldable
  • Good cutting properties
  • Physiologically harmless
  • Good weather resistance
  • Application areas:
  • Pump parts
  • Coil bodies
  • Ball-bearing casings
  • Protective casing
  • Covering


POM-C is a highly crystalline thermoplastic. It is characterised by an extremely low water absorption, very high measuring stability and optimal processing properties (short-chipping). Because of the favourable properties – high hardness, stiffness and stability combined with good toughness and chemical resistance as well as favourable friction and wear behaviour – POM-C can be used in many cases instead of metallic materials.

  • Most important properties:
  • Versatile high performance material
  • High stability and hardness
  • Very good cutting properties
  • Dimensional stability
  • Low water absorption
  • Very low creep properties
  • High chemical resistance
  • Good sliding properties
  • Physiologically harmless
  • Application areas:
  • Sliding components and rollers
  • Cogwheels, control wheels and cams
  • Ducts, sliding plates
  • Valve seats and bodies
