Overview
Polychloroprene Rubber CR244 is a chloroprene polymer regulated with diisopropyl xanthogen disulfide or dodecyl mercaptan. It has a fast crystallization rate, a density of 1.23, and appears as off-white or beige flakes. It has a regular molecular structure and high cohesive strength, resulting in high adhesive strength at room temperature, making it the main base material for chloroprene adhesives.
