Non-asbestos
Gasket（CNAF Gasket,Asbestos-free Gasket）
Item No.:ZD-G1530
Description:Non-asbestos
gaskets come in a variety of basic materials comprised of carbon,
graphite, fiberglass, aramid fiber, Kevlar and other mineral fibers. The
basic components of the non-asbestos materials used in gasket
construction are elastomer and filler.Add special adhesives and a little
packing into it, then roll and sulfurated. The elastomer composition
corresponds to the application of the gasket, assisting in the
categorization and selection of the gasket best used for the service it
will be performing. It is a replacement of asbestos gasket.
Non-asbestos Gasket has better
strength, elasticity.It has supper strong
anti-penetrate performance. Non-asbestos Gasket is a better choice than
asbestos gasket in high temperature and high pressure condition. And
Non-asbestos Gasket is product using material with environment
protection.
Typical Properties of Common Elastomers (Rubber
Compounds)
NBR - good for oils, gas, mild chemicals and water
SBR - good for saturated Steam, mild chemicals inert gas and water
Neoprene - good for saturated steam, refrigerants, oils, fuels, mild
acids and alkalies and water.
EPDM - good for saturated steam, mild chemicals and water
The Process:Gaskets
can be cut based on your drawing or sample of the gasket you
desire. Basic I.D. x O.D. shapes can be cut by hand however most die
cuts gaskets require a die.The size are according to API or DIN
standard, also we can produce non-standard as clients' request.
Application:Non-asbestos
Gasket are widely used in the industries such as gas, hydrocarbon,
solvent, low pressure steam, weak acid and alkali etc.They are applied
to some industries of food, mechanical, chemical engineering, petroleum
and so on.

Warning: Gasket materials should
never be recommended when both the
temperature and the pressure are at
the maximums listed. Properties and
applications shown are typical. No
application should be undertaken by
anyone without independent study and
evaluation for suitability. Never
use more than one gasket in one
flange joint, and never reuse a
gasket. Improper use or gasket
selection could cause property
damage and/or serious personal
injury. The data reported is a
compilation of field testing, field
service reports and/or in-house
testing. While the utmost care has
gone into publishing the information
contained herein, we assume no
responsibility for errors. The
