Closed Cell Neoprene Rubber

Neoprene was invented by DuPont as the first mass-produced synthetic rubber compound. The chemical inertness of closed cell Neoprene makes this material suitable for many industrial and flexible sealing applications, such as gaskets used in electrical enclosures and weather stripping. Properties like gasoline and oil resistance, chemical resistance and UV resistances enable the use of Neoprene in a wide range of industrial gasket applications and automotive products. Atlantic Gasket Corporation is a custom gasket manufacturer experienced and highly skilled at producing parts and components in Neoprene closed cell sponge as thin as 1/16" thick up to 1" thick. Examples of suitable gasket and sealing applications for closed cell Neoprene can be found below.

Example Gasket Application Properties
Weatherproofing Closed cell Neoprene exhibits ideal properties suitable in applications where temperatures can range from –40° F to +200° F. This rubber gasket material is resistant to UV, oxidation, and ozone for long-term use in outdoor applications.
HVAC Due to the excellent aging characteristics of Neoprene closed cell sponge rubber and its ability to eliminate air leakage, this sealing material is known to perform well in HVAC systems.
Automotive Neoprene’s resistance to acids, oil, and gasoline make it a good choice for use in many automotive products. In applications involving consistent temperatures at 150° F, this elastomer is able to maintain high performance.
Electrical Enclosures The closed cell structure of our Neoprene, which creates a water / air tight seal, enables its use in a large number of electrical applications.

Is neoprene the best choice for your gasket or seal application? Find out the answer by reading on.
  • Does your sealing application require a gasket material that is resistant to acids, alkalis, gasoline, oil, oxidation and UV? Will your gasket need to confirm to irregular shapes and seal under minimum pressure? If your answer is yes, please contact us to discuss your specific requirements so that we can determine which grade of our closed cell Neoprene will work best in your application.
  • Are the components in your end product required to meet strict specifications? Depending on the grade, our Neoprene gasket material adheres to:
  • ASTM-D-1056-07 2C1
  • ASTM-D-1056 B2,F1,m
  • ASTM D-6576-07 Type II A. B Soft-soft-medium and medium
