Chloroprene Rubber CAS 9010-98-4

Chloroprene Rubber (CR), commonly referred to as polychloroprene, is a general-purpose synthetic elastomer used across rubber processing industries where resistance to oil, weathering, ozone, and moderate heat is required. It is widely applied in molded rubber goods, industrial belts, wire and cable sheathing, and adhesive formulations.

In commercial supply, Chloroprene Rubber is typically provided as solid bales or chips suitable for compounding and further processing. Different grades are available depending on polymerization type and application direction (e.g., general molding, adhesives). Standard export packaging is used, with supporting documents such as COA, TDS, and SDS available for industrial procurement.

Typical Applications

  • Industrial rubber products: Used in hoses, belts, gaskets, seals, and molded rubber parts requiring balanced mechanical and aging properties.
  • Adhesive formulations: Widely used in solvent-based adhesives for bonding rubber, metal, leather, and other substrates.
  • Wire and cable sheathing: Applied as protective insulation material due to its weather and flame resistance characteristics.
  • Coated fabrics and construction materials: Used in applications such as conveyor belts, coated textiles, and waterproofing systems.

Packaging

Chloroprene Rubber is typically supplied in solid bale or block form, wrapped in protective film and packed in cartons or on pallets for handling and transportation. The packaging is designed to prevent contamination and maintain material integrity during storage and shipment.

For export supply, bales are usually palletized and secured to facilitate safe loading and unloading. Packaging configurations may vary depending on grade type and order quantity.

Storage

Store in a cool, dry, and well-ventilated warehouse away from direct sunlight and heat sources. Avoid prolonged exposure to high temperatures to prevent premature aging of the polymer. Keep packaging intact and avoid contamination with dust, oils, or incompatible materials.
