Product Description
Polychloroprene Rubber(CR)
Polychloroprene Rubber 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 Dupont Type W and Japanese Type M40 polychloroprene rubber.
Polychloroprene Rubber(CR) is characterized by excellent storage stability, process ability and safety property and its products have weatherability, oil resistance, chemical reagent resistance and flame-retardance as well as heat resistance and less compression deformation. But Polychloroprene Rubber(CR) vulcanization rate is slow and should be solved by adjusting the vulcanization system.
. Appearance:
Creamy flaky or lumpy matter from mechanical impurities (except talc powder)and scorched particles.
Application
Polychloroprene Rubber CR232 can used for manufacturing oil-resistant rubber hose and rubber boards, cable jackets, rubber sealing parts, etc, and is also widely used in making adhesive.
