PTFE Gaskets include pure PTFE gasket,expanded PTFE gasket,filled
PTFE gasket and PTFE spiral wound gasket.
Pure PTFE gasket is manufactured by molding method with PTFE granular resin. PTFE
compared with other plastics, has a superior properties against
chemicals and temperature. Because of such excellent properties,
PTFE has a wide application as a sealing material.

Filled PTFE gasket is manufactured by moding method with filled PTFE resin. Filled
PTFE resin is manufactured by compounding PTFE granular resin with
fillers of many differents kinds. Amongst the many fillers suitable
for compounding with PTFE, glass fiber, carbon fiber, Bronze and
also lubricating materials like graphite, molybdenum disulphide,
have been widely used in large scale production, Broadly speaking
PTFE compounds have the following advantage over unfilled.

PTFE spiral wound gasket is corrosion resistant and high pressure product. By winding metal
with PTFE is model PTFE spiral wound gasket. It could fix the outer
ring or inner ring, even with outer and inner ring.
