When the elastomer compounds of polyvinyl chloride (PVC) and Nitrile (Buna-N) combine, excellent energy / impact absorbing properties and good chemical resistance properties are demonstrated. Closed cell PVC/Nitrile sponge rubber is a premium gasket and seal material and is also an excellent material for padding and shock absorption applications.
Specifically, closed cell PVC/Nitrile sponge rubber is used as protective padding in personal protective equipment, sports gear, and many other commercial applications. Gasket Supply is a leading manufacturer of gaskets and CNC cut parts fabricated from PVC/Nitrile closed cell sponge.
EXAMPLE GASKET APPLICATIONS OF PVC/NITRILE CLOSED CELL SPONGE RUBBER
GASKETS & SEALS
The fine closed cell structure, chemical resistance and UL 94 flammability rating makes closed cell PVC/Nitrile the perfect gasket material for many products.
SHOCK ABSORPTION & PADDING
With excellent shock and impact absorbing characteristics, PVC/Nitrile closed cell sponge is an excellent material for protective padding in athletic equipment or in any other application that requires an energy absorbing material.
AVAILABLE GRADES OF CLOSED CELL PVC/NITRILE SPONGE RUBBER
Depending on the grade, Gasket Supply’s PVC/Nitrile (Buna-N) gaskets and seals meets the following specifications: ASTM D 1056-68, 1056-85, 91, 98, UL 94 HF-1, UL 94 VO, and FMVSS-302.

Our MLC and MLC-2 grades are available in thicknesses ranging from 1/16″ up to 1½”, in rolls 56″ wide by 75 ft. long. Both grades have a fine cell structure, good chemical resistance and are fire rated. MLC is supplied in a black color, while MLC-2 is supplied in a natural (tan) color and is our softest grade.
Our AHC grade is available in thicknesses ranging from 1/16″ up to 1¼”, in rolls 56″ wide by 96 ft. long. AHC is a premium padding material with excellent shock absorption properties. This material also meets UL 94 HF-1 and UL 94 VO specifications for flammability.
Our SSC and SCC grades are available in thicknesses ranging from 1/16″ up to 1″, in rolls 56″ wide by 100 ft. long. Both materials are high density, have a very fine cell structure and exhibit low compression set. SSC is supplied in a black color, and SCC is available in gray and natural (tan) colors.
Our team can also slit rolls starting as narrow as 1/4″ or use CNC or waterjet cutting methods to create gaskets to your exact specifications.
