Chloroprene Rubber (Type CR244)
Commodity: Poly Chloroprene Rubber (CR in brief), Neoprene
CAS No.: 9010 - 98 - 4
H. S. Code: 4002 4910
Description:
A rapidly crystallizing chloroprene polymer stabilized with a thiuram disulfide. It is designed for quick-setting cements and adhesives. The stabilizers have been added. Raw polymer stability is very good. Excessive time and temperature of storage can cause an increase in viscosity. It is similar to Du Pont's neoprene type AD-20 and Denka's A-90.
Application:
Polychloroprene rubber CR244 is recommended widely for making adhesives, applied to adhint various materials, such as shoes, rubbers, leathers, plastics, furniture and metals, etc.
Packing:
Woven polypropylene lined-kraft paper bags with a release polyethylene liner, 25kg net WT each.
Storage life: One year below 5 from the dtae of production.
Remark: Comparison sheet of CR types from Different Makersduction.
