Product Description
Polychloroprene Rubber Type CR322
Polychloroprene Rubber Type CR322 is a general purpose polychloroprene rubber of low crystallization rate made by polymerizing the emulsion with sulphur and modified(biisoropy Xanthogenate)as mixed modifier and petroleum sodium sulfonate as disperser, and non-pollutant anti-ageing agents used separately, and similar to Dupont Neoprene Type GW.
1. Characteristics:
Polychloroprene Rubber Type CR322 is characterized by good physics-mechanical performances, sunlight resistance, weather resistance, ozone ageing resistance, chemical regent resistance, oil resistance, combustion retardant, air impermeability, flexibility resistance, electric insulation, and more excellent tearing strength than CR121. Polychloroprene Rubber Type CR322 has good process performance, and is easy to plasticize, mix-melt and extrude to form. Polychloroprene Rubber Type CR322 also has smooth surface, good appearance and satisfactory processing safety.
Appearance: Creamy flaky or lumpy matter generally, free from mechanical impurities(except talc powder).
Application:
Due to its excellent comprehensive performances, Polychloroprene Rubber Type CR322 is widely applied to make various cables, chloroprene cloth wires, plain and oil resisting hoses, rubber boards, air ducts, conveyer belts, driving belts, tent cloth, waterproof cloth, oil resisting rubber boots, sealing parts, agricultural encapsulated air cushions, lifeboats, etc Polychloroprene Rubber Type CR322 is more for various for various bright color or light-color.
