H.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 Pont’s neoprene type AD-20 and Denka's A-90.
