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
Compressed
non-asbestos fiber gasket materials are used in air compressors, diesel
engines, pipelines, and most other industrial and marine applications.
Remember that as a general rule you should select the thinnest material
possible for your application. Also good for Electric Motor, HVAC, Power
and Utility, Automotive, Material Handling, Oil and Gas
