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 Butyl Rubber - BUTYI has a very high impermeability to gasses and is used for the inner tubes of pneumatic tires, and in vacuum and high pressure applications. It has an unusually broad loss peak so that, despite having a glass transition temperature as low as -65C, it displays high damping at ambient temperatures. Butyl Rubber has good ozone, weathering, heat and chemical resistance. It is not suitable for use in contact with mineral oils. Butyl rubber has low resilience at ambient temperatures and is suitable for damping applications.

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 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 Ethylene-Propylene Diene Monomer - EPDM is excellent for water and steam applications. EPDM is similar to Styrene Butadiene Rubber (SBR) but has improved resistance to atmospheric aging, heat oxidization and ozone up to about 150C. Ethylene Propylene Diene Monomer has excellent electrical properties and good chemical resistance.

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.
