Polychloroprene Rubber TYPE CR244
CR244 is a special chloroprene rubber of high-crystallization rate made by polymerizing the emulsion with nonsulfur modifier as modifying agent and with Lomar Pw as disperser, and similar to Japanese polychloroprene rubber Type A--90.
Characteristics:
CR244 is characterized by high crystallization rate , strong cohesion, comparatively high adhesion strength and excellent ozone resistance, weather resistance, oil resistance and combustion retardancy.
Appearance:
Milky white to light brown lumpy matter free from mechanical impurities except talc power.
