Description:Expanded
PTFE Gaskets and Seal materials consist of virgin PTFE with
multidirectional fibrous and/or porous structure, which the extruded
PTFE consists of. A special manufacturing process provides the material
with special chemical and physical properties. This can be of advantage
in wide range of the applications.ZD-G1630
soft flexible PTFE gasket and sealing material easily conforms to
sealing surface imperfections with less torque than conventional
materials. Expanded PTFE resists cold flow and creep while offering the
widest range of sealibility, chemical resistance, and temperature
service of any material offered.
Application:Expanded PTFE gasket is
designed for use in process piping and equipment in chemical, pulp and
paper, food and beverage and other general industrial applications where
resistance to highly aggressive chemicals is required.

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
