Products

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 Chloroprene Rubber-CR has several types of polychloroprene. Chloroprene rubber mechanical properties are generally inferior to natural rubber but with superior chemical properties. Over time crystallization results in hardening at temperatures about -10 degree C. CR has very good resistance to ozone. It also has good flame retardance and good tackiness.

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 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.
