Hypalon® (Chlorosulphonated Polyethylene) Developed in the 1950s as a speciality rubber for rugged applications. Best described as a "super" Neoprene, with similar but better developed characteristics. Properties • resistant to oil and fluids, especially at higher temperatures (+125°C) • extremely resistant to ozone and weathering - can withstand harsh outdoor conditions for up to 15 years Limitations • cannot be used where there is contact with fuels Typical Applications situations where there is likely to be heavy weather conditions or exposure to hot liquids and/or gases ® Registered trademark of DuPont Dow Elastomers
