SULFUR REGULATING TYPE - DCR114
NON - SULFUR REGULATING TYPE - DCR213
Polychloroprene Rubber DCR 114
Appearance: Beige (or light brown) chips.
Description: A sulfur-modified copolymer of chioro-butadiene and dichloro-butadiene, with excellent anti-crystallization performance and good molding adhesion. It is the preferred choice for high strength dynamic products and has better low temperature properties. The density is 1.23. It is similar to Du Pont's Neoprene GRT and Denka's PS-40.
Application: For making transmission belts such as timing belts, ribbed belts, etc.
