ASTM D2000/SAE J200 Type, Class: CE

Description: Hypalon® has always demonstrated durability in harsh environments. This type of rubber is known to be used in applications that require high performance and resistance to chemicals, temperature extremes, and ultraviolet light.

Key Use(s): Used in a variety of industrial and automotive applications that require high performance and have to withstand extreme weather conditions. 

Temperature Range
Standard Compound: -45°C (-50°F) to 132°C (270°F) 

Hardness (Shore A): 45 to 95

Features: Hypalon rubber products are extremely resistant to attack by ozone, weather and oxygen. These properties make the rubber suitable for outdoor exposure in a broad range of applications.

Limitations: It has poor fuel resistance. It also has poor compression set resistance which limits its utility in dynamic sealing applications.
