Neoprene/Chloroprene Rubber CR322 Series

CR 322 Series Neoprene (Chloroprene Rubber) are chloroprene polymer with sulfur and dithiodiisopropyl xanthate as regulator.
Crystallization rate is medium,density is 1.23,beige or brown lumps,none pollution type.
They have high tear resistance, processability is better than sulfur-modified polychloroprene rubber.
Used for production of cable sheath, conveyor belt and other rubber products.
Similar to the DuPont's GW and Denka's DCR-40 neoprene.
Package: woven polypropylene lined-kraft paper bags width a release polythene liner, Net. Weight 25 Kgs.
Storage life: one year below 25 ℃ from the date of production.
