Introduction | Products | Custom Products | About PTFE
Thermal Stability
PTFE retains all its useful properties over a wide range of temperature between -250 C and 250 C.
Chemical Interness
PTFE is totally inert to all the chemicals acid or alkalies, organic or inorganic. It offers excellent moisture resistance and
is insoluble in all the solvents.

Filled Grades Of PTFE Inorganic fillers such as glass, carbon, graphite, bronze are added to PTFE to improve its mechanical and wear properties. All products mentioned here are available in filled grades of PTFE.
Glass-Filled PTFE :
Enhanced load bearing and other mechanical properties. Good chemical and electrical properties. Resists oxidation and is good in acids. Major Applications : Seals, seal rings, valve seats and valve plugs, bearings, bearing pads, gaskets.
Carbon-Filled PTFE :
Excellent load bearing, wear and frictional properties under rubbing conditions and good abrasion resistance. Among the best PTFE filler for use in water. Chemical inertness permits use in a wide variety of corrosive environments. Major Applications : Bearings, seal rings, piston rings, valve plugs and compressor rings, gaskets.
Graphite-Filled PTFE :
Reduces initial wear and improved load bearing and frictional performance. Especially well suited to high load carrying applications and high speed rubbing contact with soft metals. Major Applications : Piston and compressor rings, slide and sleeve bearings, seal rings.
Bronze-Filled PTFE :
Improved thermal conductivity, hardness, compressive strength and resistance to creep. Enhanced dimensional stability under static load. Frictional and wear properties suitable to wide range of dynamic bearings and seals. Major Applications : Valve seats and valve plugs, bearings, piston rings.
Anti-Stick Surface
PTFE surface is anti-stick. Even the commercial adhesives do not form bonds with it. It also has the lowest co-efficient
of friction.
Low Loss Electrical Properties
PTFE is an excellent insulator of electricity. Its extremely
low dielectric constant is retained at extremely high frequencies.
