Compressed Non-asbestos Fiber Gasket

Compressed Non-asbestos Fiber Gasket - Style NA Series

Compressed non-asbestos fiber gasket is a general purpose gasket jointing material with superior mechanical properties. It is constructed with premium aramid fiber and a high quality nitrile rubber or SBR binder. Compressed non-asbestos fiber gasket is effective for use with mild organic and inorganic acids, diluted alkalis, general chemicals, synthetic oils, petroleum and petroleum derivatives.

Many products designed to replace asbestos material have seen extensive use since the 1970s, however choosing a replacement material for compressed asbestos warrants careful consideration. Most manufacturers of compressed non-asbestos fiber gasket materials use synthetic fibers like aramid or Kevlar® in conjunction with an elastomeric binder. The elastomeric binder makes up a larger percentage of this sheet and thereby becomes a more important consideration when determining applications. Kevlar® is a registered trademark of DuPont.

Typical Features

Compressed non-asbestos fiber gasket material has excellent chemical resistance, wide temperature range, excellent resistance to stress, high levels of joint stability, outstanding sealing integrity and long lifespan.

Applications and Uses of Compressed Non-asbestos Fiber Gasket
