EPDM is generally characterized by its superior resistance to heat, aging and chemicals, good low-temperature behaviour and good electrical insulation properties. These properties allow a long service life under static load. EPDM is widely used in the automotive industry and in washing machines and dishwashers, as EPDM achieved good results compared with suds and cleaning solutions at higher temperatures. The resistance to hot water and steam is particularly good, so it is also well suited for gaskets and hoses in heating and the fittings and household appliance industries. The temperature range for continuous use is from about -30°C to +130°C, for short-time use approx. -50°C to +150°C.

Vulkanisates of SBR with reinforcing fillers get nearly to the same level according to mechanical properties like NR. The abrasion resistance as well as heat and ageing resistance are even better but with lower elasticity and low temperature flexibility. In addition to the main range of application tires there are also articles like e. g. seals, profiles and hoses made of SBR. The temperature range for continuous use is from about -30°C to +100°C, for short-time use approx. -50°C to +120°C.

The products made of CR are characterized by high flame retardancy, good weather, chemical, ozone and aging resistance, medium oil resistance with good mechanical properties and favourable elastic behaviour, even at low temperatures. The fields of application are e.g. in the scope of hoses, seals, conveyor belts (e.g. underground construction). The temperature range for continuous use is from about -20°C to +100°C.
