CR244

CR244Commodity : Poly Chloroprene Rubber ( CR in brief ) ,Neoprene CAS No. : 9010 98 4H.S.Code : 4002.49.10 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 Ponts neoprene type AD-20 and Denkas A-90.
