Overview JiangSu ElephChem Holding Limited offers a wide range of chloroprene rubber products, primarily including seven major series: CR244, CR248, CR232, CR121, CR322, DCR213, and DCR114. These products boast a complete range of grades, excellent quality, and outstanding cost-effectiveness. They include slow-crystallizing, cold-resistant rubber series products comparable to those of Denka and ARLANXEO, and have received widespread acclaim from domestic and international customers.
Overview Neoprene Chloroprene Rubber CR121 is a chloroprene polymer with sulfur as a modifier. It has a medium-low crystallization rate, a density of 1.23, and is a beige or light brown lumpy substance. It possesses good tear resistance and flexural strength.
Overview This product is a chloroprene polymer with diisopropyl xanthogen disulfide or dodecyl mercaptan as a regulating agent. It has a medium crystallization rate, a density of 1.23, and is an off-white or yellowish block-shaped solid. It possesses good heat resistance and high-temperature stability.
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.
