polychloroprene การใช้

• Natural rubber and polychloroprene ( Neoprene ) are commonly used contact adhesives.
• The expansion of the production facility for Baypren polychloroprene solid rubber was completed at Dormagen.
• Ozone-resistant elastomers include EPDM, fluoroelastomers like Viton and polychloroprene rubbers like Neoprene.
• Ethylene thiourea is an excellent and proven accelerant of vulcanization of neoprene and polychloroprene rubbers.
• Polychloroprene is better known to the public as Neoprene, the trade name given by DuPont.
• This colorless liquid is the monomer for the production of the polymer polychloroprene, a type of synthetic rubber.
• The company manufactures and markets a variety of Synthetic Adhesives based on Polychloroprene, Polyurethane, Epoxy, EVA, Lamination and other Elastomers.
• Typical rubbers used conventionally include natural rubber, nitrile rubber, polychloroprene, polybutadiene, styrene-butadiene and fluorinated rubbers such as Viton.
• Low to high polarity esters provide utility in a wide range of elastomers including nitrile, polychloroprene, EPDM, chlorinated polyethylene, and epichlorohydrin.
• In the vulcanization of neoprene or polychloroprene rubber ( CR rubber ) the choice of accelerator is governed by different rules to other diene rubbers.
• Historical uses of hydrogen chloride in the 20th century include hydrochlorinations of alkynes in producing the chlorinated monomers chloroprene and vinyl chloride, which are subsequently polymerized to make polychloroprene ( Neoprene ) and polyvinyl chloride ( PVC ), respectively.
• Most conventionally used accelerators are problematic when CR rubbers are cured and the most important accelerator has been found to be ethylene thiourea ( ETU ) which, although being an excellent and proven accelerator for polychloroprene, has been classified as reprotoxic.
