Chlorosulphonated polyethylene properties

Chlorosulphonated polyethylene was first introduced by DuPont as Hypalon, a trade name in the year 1952. Chlorosulphonated polyethylene compounds have good heat and oxygen and ozone resistance, moderate oil resistance and excellent electrical properties, but their main features for use in the chemical process industries is their resistance to strong oxidizing chemicals. 

Another similar polymer, chlorosulphonated polyethylene (Hypalon), also requires special modifications to achieve adequate adhesion, but in this case it is the basic polymer formulation that is modified, by the addition of from 20 to 40% of NR this gives a good increase in achieved adhesion without too great a loss of the outstanding weathering and ageing properties of the polymer.
