Knowledge about Neoprene Rubber

by Dongrubber on September 17, 2006 · 0 comments

Neoprene rubber has an abbreviation of CR, which is short for chloroprene rubber. CR rubber sheet was the first commercial synthetic organic rubber of the world, most of which is predominantly tran-1,4-polychloroprene. The ingredient is obtained by emulsion polymerization using free radical polymerization. Neoprene rubber has a high cohesive strength without curing due to its low polymerization temperatures that are used to make CR grades useful in adhesives.

Neoprene rubber mouldings are highly resistant to oxidation; it can be compounded with carbon black and anti-oxidants. Compound of neoprene rubber shows good long term outdoor weathering properties. CR rubber sheet is also resistant to ozone-cracking and with a high level of resistance to paraffnic oils and solvents. Neoprene rubber exhibits a very good flame reistance due to the large amount of chlorine contained in its structure. But CR rubber mouldings lose the flexibility quickly because the temperature is lowered and the raw polymer compounds harden during storage.
