Resistance to silicone oils and greases, refrigerants; better ozone resistance, weather resistance and aging resistance to NBR. Temperature range from -40°C to approx. 100°C, short-term up to 120°C.
Chlorinated rubber is not unlike PVC. Low water vapor permeability, good resistance to low and high temperatures, to moisture, acids, salts, and alkalis are the hallmarks of “CR”.
Ethylen- Propylen- Rubber
The saturated framework structure leads to properties such as high weather and ozone resistance and high thermal resistance.
Because of its high elasticity and good chemical resistance, it is used for various seals such as O-rings in mechanical seals or flat seals. EPDM is a common material for hoses used for steam or hot water.
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 like that of butyl rubber. Special FKM compounds have a higher resistance to acids, fuels, water, and steam.
Heat resistance: up to about +200°C for a short time up to 250°C
Cold resistance: up to about -25°C (partly -40°C static).
Acrylonitrile - Butadiene - Rubber
The vulcanizates made of nitrile rubber are highly resistant to oils, fats and hydrocarbons, have good aging properties and low abrasion. They are used in the manufacture of seals, hoses, rubber gloves, and rubber threads.
Much more durable than the conventional synthetic variants and is therefore used, for example, for heavily loaded tire 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 aging resistance and ozone resistance.
