Polychloroprene Rubber
This product is a non-pollutant type chloroprene rubber of medium crystallization rate ,a variety of general purpose rubber , made by polymerizing the emulsion with petroleum sodium sulfonate as disperser and non-sulfur modifier as modifier as modification agent, and similar to American Type W and Japanese Type M40 polychloroprene rubber.
1. Characteristics:
This product is characterized by excellent storage stability, process ability and safety property , and its products have sunlight resistance, oil resistance, chemical reagent resistance and combustion retardancy as well as heat resistance and less compression deformation. But its vulcanization rate is slow and should be solved by adjusting the vulcanization.
