Pure
PTFE Gasket，Polytetrafluoroethylene Gasket
Item No.:ZD-G1600
Description:
ZD-G1600
is made by cutting PTFE stick, pipe and sheet into flat shape PTFE
gasket, v shape PTFE gasket or valve annulus PTFE gasket.PTFE gasket has
100% PTFE structure.It can bear the most bitter chemical medium, and
PTFE gasket has good anti-creeping performance.PTFE gasket is a
replacement of asbestos,and it is anti-creeping, anti-cold-flow,
anti-low-temerature.PTFE gasket has no pollution and is easy to install
and replace. under small pre-stress force,it can bear great internal
pressure even in a environment of changing pressure. It is the
best suit the condition with rough and fragile flange and
alternately-changing temperature.

PTFE Gasket
Item No.:ZD-G1610
Description:As
we know,PTFE gasket is anti-creeping, anti-cold-flow, anti-low-temerature
and PTFE gasket has no pollution. If we add some more useful element
into the PTFE,the compression resistance and high temperature resistance
will be more perfect.For example,can add some fibreglass,graphite,bronze
to improve the character of pure PTFE gasket.We have PTFE gasket
reinforced with glass fibre,graphite PTFE gasket,reformative PTFE
gasket,PTFE bronze gasket,ect.
PTFE Graphite-filled Gasket:PTFE(teflon)
graphite-filled is synthetic material made of PTFE and grapphite.It has
perfect compressibility,recovery and sealing capability.Compared with
traditional PTFE,it improve the low-flow and creep properties.It
is more durable than normal PTFE gasket and extend the maintenance
period of flange.So PTFE(teflon) graphite is economical choice.
PTFE Glass-filled Gasket:It

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
