Customized PTFE Gaskets Teflon Auto Parts
EPDM is a black plate finish sheet with superior resistance to weathering, ozone and UV exposure. EPDM gaskets provide excellent chemical resistance, and good electrical properties. EPDM gaskets resists animal and vegetable oils, steam, water and oxygenated solvents.
High grade material including Mil-specification is available.
EPDM gaskets are also available in a white FDA approved material.

PTFE Gasket FYR
Virgin PTFE is by far the least expensive of the three varieties, and is used in most general applications. Filled PTFE is a gasket material with a virgin PTFE base to which a substance is added during manufacture to improve the sealing characteristics of PTFE . This "filler" usually is glass or graphite particles although ceramics has sometimes been used. The resulting gasket material is strong, yet highly compressible with very good, though not universal, chemical resistance.
Expanded PTFE is virgin PTFE to which a stress resistance has been added by means of molecular rearrangement during manufacture. This process ensures that the molecular chains from which the PTFE is constructed, do not arrange themselves into set patterns. This means that expanded PTFE possesses no structural weakness (grain) and expands and contracts equally in all directions. Because no additives are required, expanded PTFE also possesses the unique chemical resistance of virgin PTFE
