Chloroprene Rubber CR Rubber Natural Rubber
A. performance characteristics
The product has good physical and mechanical properties, good plastic solution features..With rubber and other types, has good compatibility.Has good resistance to oil, chemicals, resistant to ozone aging, sunlight resistance, has excellent don't delay flammability and better performance, security and stability of the processing.Compared with CR322 SN321 Mooney viscosity, stability, uniform processing performance is better, are more likely to plasticate, mixing and extrusion molding, film surface level off is smooth, small shrinkage, good appearance.With the United States DuPont GW type neoprene have equal processing performance.
B. Specification
