Hypalon Characteristics and Uses
Hypalon Rubber, previously a registered trademark of DuPont Elastomers, are a a group of peroxide and sulfur curable elastomers based on chlorosulfonated and chlorinated polyethylene. As a result of the manufacturing process, these polymers produce an elastomer with a completely saturated backbone as well as pendant groups suitable for varied vulcanization approaches. Due to its unique backbone configuration, Hypalon rubber vulcanizates are extremely resistant to attack by ozone, weather and oxygen.
Because of its unique properties, hypalon rubber parts perform very well in the following areas of application:
Rubber Hoses
Hypalon's unique properties are specifically useful in power steering and oil cooler hoses for industrial and automotive hydraulic hose applications where impulse testing can be performed at temperatures up to 300°F. Hypalon rubber is also used for a variety of fuel hose covers and various vacuum and emission tubing applications.
Cable Sheathing
Hypalon rubber is also used widely in sheathing applications for cable constructions. In these applications it is often specified for its resistance to weathering, sunlight, ozone, and heat.
Hypalon Roll Covers
Roll covers made of Hypalon material will resist a large variety of chemicals and solvents over a wide range of temperatures while also possessing resistance to wear and good resilience.
