Overview of our plastics: premium materials that meet the most challenging requirements

Glass-fibre reinforced polyester (thermoset) – excellent chemical resistance, high weather and UV resistance, shock resistant, the ideal material for rigid and dimensionally stable parts.

Polymethyl methacrylate (PMMA) is a synthetic, glass-like thermoplastic material. It is also known colloquially as acrylic or plexiglass.

Excellent light transmission (better than mineral glass), easy to colour, weather and ageing resistant, also resistant to acids, alkalis of medium concentration, petrol and oil. However, ethanol, acetone and benzene can damage PMMA. Therefore, plexiglass surfaces must not be cleaned with alcohol or solvents, as this can cause stress cracking.

Light transmission: 92%

Polycarbonates are plastics belonging to the group of synthetic polymers and the polyester family. Specifically, they are polymeric esters of carbonic acid with diols (dihydric alcohols)

and are known for their high strength and excellent shock resistance, rigidity and hardness. Polycarbonates are largely resistant to the effects of weather and radiation.

They are also resistant to water, many mineral acids and aqueous solutions of neutral salts and oxidising agents. However, polycarbonates can be damaged by some chlorinated hydrocarbons, as well as alkaline aqueous solutions, amines and ammonia.

Light transmission: 89%

EPDM is a terpolymer elastomer – a synthetic rubber renowned for its exceptional resistance to weather, moisture and ozone, as well as its excellent thermal stability.

Thanks to its high elasticity and excellent chemical resistance, EPDM is used for various seals, such as O-rings in mechanical seals and flat gaskets.

Our soft, elastic foam seal with a cross-linked structure is resistant to external influences such as moisture, dust and temperature, offering excellent long-term performance in continuous use.
