Shanghai Potomer TYPE CR--232 CR2323 Chloroprene rubber
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	CR232 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. Characteristics: CR232 is characterized by excellent storage stability, processability 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 system Application: 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.
