Raw material guidance




Temperature range: -40°C up to +100°C, short-term up   to 120°C.

Resistance to silicone oils and greases,   refrigerants; better ozone resistance, weather resistance and ageing   resistance than NBR. Chlorinated rubber is very similar to PVC. Low water   vapour permeability, good resistance to low and high temperatures, moisture,   acids, salts and alkalis are the hallmarks of "CR".


The saturated framework structure leads to   properties such as high weather and ozone resistance as well as high   temperature resistance. Due to its high elasticity and good chemical  resistance, it is used for various seals such as O-rings in mechanical seals   or flat gaskets. EPDM is also a common material for hoses used with steam or   hot water.  

However, EPDM is not resistant to aliphatic and   aromatic hydrocarbons and mineral oil products. Depending on the   cross-linking system (sulphur or peroxide cross-linked) and the compound  setting, a temperature range between -45°C and +160°C is possible.


Temperature range: -40°C up to +250°C  

FKM has excellent resistance to high temperatures,   ozone, oxygen, mineral oils, synthetic hydraulic fluids, fuels, aromatics,   many organic solvents and chemicals. Gas permeability is low and similar to   butyl rubber. Special FKM compounds have higher resistance to acids, fuels,   water and steam.
eat resistance: up to approx. +200°C for short   periods up to 250°C
Cold resistance: down to approx. -25°C (sometimes   -40°C static). 


Temperature range: -40 °C up to +130 °C  

The vulcanisates made of nitrile rubber are highly   resistant to oils, greases and hydrocarbons, have good ageing properties and   low abrasion. They are used in the manufacture of seals, hoses, rubber gloves   and rubber threads. 

Natural rubber

Temperature range: -50°C to +90°C  

Much more hard-wearing than the conventional plastic   variants and is therefore used, for example, for heavy-duty tyre applications   in the construction industry. NR has good mechanical properties (very high   strength, high elongation at break, very high impact elasticity and good  abrasion resistance). However, no resistance to mineral oils and greases and   very low ageing and ozone resistance.


Temperature range: -200°C up to +260°C  

PTFE is absolutely weather- and UV-resistant. It is   physiologically harmless and scores points for its excellent sliding   properties. The material is universally resistant with the exception of   liquid alkali metals and fluorine gases.


Polyurethane is a material that has ideal properties   for numerous industrial applications. It has a high tensile strength and   elasticity. In addition to high wear resistance, it is also resistant to  mineral oils and greases.
