CHLOROPRENE RUBBER TYPE CR232

This products is a non-pollutant type chloroprene rubber of medium crystallization rate, a variety of general purpose chloroprene rubber, made by polymerizing the emulsion with petroleum sodium sulfonate as disperser and non-sulfur modifier as modification agent, and similar to American Type W and Japanese Type M40 chloroprene rubber.

1.Characteristics:
This product is characterized by excellent storage stability, processability and safety property, and its products have sunlight resistance, ozoneageing resistandce, 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.

2.Specifications:
In conformity with Standard Q/SHJS 02,01-91.
a.Appearance:Creamy flaky or lumpy matter from mechanical impurities (except talc powder) and scorched particles.
