Dynacast Industrial Products Natural Rubber - NR is a general purpose rubber with the optimum balance of physical properties essential for high performance engineering applications. It has a long fatigue life and high strength even without reinforcing fillers and is the first choice for spring applications. It can be compounded to give a wide range of hardness. Good low temperature flexibility, excellent elasticity with strong ensile and good elongation. Its chief disadvantage is its poor oil resistance and its lack of resistance to oxygen and ozone, although these latter disadvantages can be ameliorated by chemical protection.

Dynacast Industrial Products Silicone Rubber - Q has good high and low temperature resistance and good electrical properties. The outstanding property of Silicone rubber is the very wide temperature range. Typically the range is -60C to 200C and above. Silicone rubber does not have very good physical properties, but the properties they do have are retained to high temperatures. Beware corrosion if acetic acid is present as a curing agent.

Dynacast Industrial Products Butadiene Rubber-BR has low hysteresis, good temperature flexibility and high abrasion resistance under severe weather conditions. It is used in blends with SBR and natural rubber. Butadiene rubber has poor processing properties and poor tear properties.

Dynacast Industrial Products Nitrile Rubber - NBR is copolymer of butadiene and acrylonitrile. With Nitrile rubbers, the oil resistance increases as the acrylonitrile content but at the expense of resilience. NBR has good oil and liquid fuel resistant and good gas barrier properties.

Dynacast Industrial Products Epichlorhydrin Rubber - CSM has good oil, low temperature resistance. ECO also has good resistance to hydrocarbon solvents combined with moderate low temperature flexibility, poor abrasion resistance and electrical properties.

Dynacast Industrial Products Isoprene Rubber - IR has very similar properties to natural rubber as Isoprene rubber is a synthetic natural rubber. This is the same polymer as natural rubber - but made synthetically. Isoprene rubber is essentially similar in properties to natural rubber but it may be somewhat weaker.

Dynacast Industrial Products Styrene Butadiene Rubber - SBR is a general purpose synthetic rubber. It must be compounded with reinforcing fillers for high strength and then has physical and chemical properties similar to natural rubber. Styrene Butadiene Rubber's abrasion resistance is better than natural rubber. it has good elasticity, and good low temperature properties but poorer fatigue resistance.

Dynacast Industrial Products Fluoro-silicone Rubber - FVMQ has good high and low temperature resistance. FVMQ also has good oil, solvent and petrol resistance.

Dynacast Industrial Products Fluorocarbon Rubber - FKM has high temperature resistance, good oil resistance, chemical products resistance and flame resistance. FKM's low temperature properties and elasticity are poor.

Dynacast Industrial Products Polyurethane Rubber - PU has good impact, abrasion, heat and chemical resistance with strong tensile strength. Polyurethane Rubber's upper temperature limit is typically 80C. They have excellent resistance to weathering and oxidation. They resist hydrocarbon fuels and mineral oils but some grades hydrolyse in hot water. They are one of the best rubbers for abrasion resistance and are therefore used in reciprocating seals. Some grades are castable.
