CR244

Chloroprene Rubber CR 244

CAS NO.: 9010-98-4


A xanthogen-modified polychloroprene rubber with fast crystallization rate,high cohesioin force and adhesion strength at normal temperature. Fast crystallization rate, density 1.23, milky or light brown block, non-polluting. Its molecular structure is regular, its cohesion is high, and its adhesive strength is high at room temperature.   Used maily for production of adhesives. It is similar to Du Pont's neoprene type AD-20 and Denka A-90.
