Polychloroprene rubber hoses

Polychloroprene rubbers find use in such applications as cable-sheaths, hose and weather strips. Latices are used in the production of dipped goods, such as gloves and balloons, foams, adhesives and corrosion-resistant coatings. 

Butadienes two double bonds make it very reactive. It readily forms polymers, reacting with itself to form polybutadiene. Its also used as a comonomer to make styrene-butadiene rubber (SBR), polychloroprene, and nitrile rubber. These are all forms of synthetic rubber and account for about 75% of the butadiene consumed. The largest share of them is on highway vehicles—truck and car tires, hoses, gaskets, and seals. 

Elastomers, synthetic-polychloroprene Elastomers, synthetic-ethylene-propylene-diene rubber). Tires, hoses, bdts, molded and extmded goods, and asphalt products consume ca 80% of the redaimed mbber manufactured. Typical properties of reclaimed mbbers are shown in Table 5. 

Depending on the grade of polymer, polychloroprene can be vulcanized by zinc oxide or magnesium oxide. Tetramethylthiuram disulfide can serve as a retarder. Polychloroprene is inferior to NBR for oil resistance but is still significantly better than natural rubber, SBR, or BR. Like NBR it also finds extensive use in such products as oil seals, gaskets, hose linings, and automotive engine transmission belts where resistance to oil absorption is important. Butyl rubbers are a copolymer of isobutylene and isoprene ... 

Uses Accelerator for polychloroprene elastomers, halobutyl rubbers esp. chlorobutyl used for mech. goods, cables, hoses, membranes, fabric proofings, vulcanizing sol ns.
