Factory Direct Sale Embossed Neoprene with Reach Certification

Neoprene is made from chloroprene (2-chloro-1,3-butadiene) as the main raw material α- Synthetic rubber produced by polymerization is widely used in anti-weathering products, viscose soles, coatings and rocket fuels.

Product application

CR122 neoprene: transmission belt, transport belt, wire and cable, oil-resistant rubber plate, oil-resistant rubber hose, sealing material and other rubber products.

CR232 neoprene: cable sheath, oil-resistant rubber hose, rubber seal, adhesive, etc.

CR2441 2442 neoprene: raw material for adhesive production, used for bonding metal, wood, rubber, leather and other materials.

CR321 322 neoprene: cable, rubber plate, common and oil-resistant rubber hose, oil-resistant rubber boots, wind guide, rain cloth, tent cloth, conveyor belt, conveyor belt, rubber seal, agricultural capsule air cushion, lifeboat, etc. It is used as toughening agent of modified acrylate fast structure adhesive (SGA).

Chloroprene rubber is produced by lotion polymerization, and the production process is mostly single kettle batch polymerization. The polymerization temperature is mostly controlled at 40~60 ℃, and the conversion rate is about 90%. High polymerization temperature, high final conversion or air (oxygen) entering the polymerization process will lead to product quality degradation. The molecular weight is adjusted by sulfur-turrum (tetraalkylmethylaminothiocarbonyl disulfide) system in production. The main disadvantage of sulfur-turam system is that the sulfur bond is not stable enough, which is one of the important reasons affecting the storage. If the molecular weight is adjusted by mercaptan, this performance can be improved. Unlike general synthetic rubber, neoprene is vulcanized with zinc oxide and magnesium oxide instead of sulfur.

Neoprene can be used as an insulator in power transformers, bulbs and other electrical applications due to its fireproof and anti-static properties. Neoprene is also used for electrical sealing gaskets to provide waterproof sealing, heat resistance and anti-static, and to prevent the entry of dust and pollutants.
