Features

Thermal Properties
PTFE has the excellent nature of retaining its material characteristic after exposure to considerably high temperatures, compared to other thermoplastics and elastomers, and can be used in temperatures as high as 500 F.
Resistance to Flame
Owing to its high melting point, thermal degradation boundaries and ignition temperature, PTFE Valve Seat, Lined Ball Valve offers stellar resistance to flames and high temperature produces way less amount of smoke.
Wear and Tear Resistance
When used in conjunction with organic filler materials like carbon/graphite, its abrasion resistance can be easily amplified, and also boasts one of the lowest known coefficients of friction values for any material.
Less Prone To Contamination
Being chemically inert, it cannot be laced with additives like lubricants, stabilizers and other antioxidant adulterants, making it a relatively safer and non-toxic choice.
Non Adhesive Nature
Owing to its extremely low value of surface energy, PTFE proves to be highly non-sticky and provides for a non-wettable surface contact, which stands true even in its liquid form.
Low Temperature
The Properties of PTFE are not affected even at extremely low temperatures and also provides stellar impact resistance at such temperatures.
Retention Of Material Characteristics
PTFE does not lose its signature material characteristics on exposure to oils, solvents, oxidizing agents and UV light.
Stability to Electromagnetic Radiations
Since PTFE boasts considerably low value of refractive index, its physical attributes do not undergo any form of change.
An Excellent Dielectric
PTFE exhibits stellar dielectric properties and possesses high values of dielectric strength and specific resistance, in addition to minimal dielectric constant and loss factors.

Properties

PTFE is known to be a highly versatile material and has spawned a number of variants, each of whom a different set of physical and chemical characteristics, suitable for any diverse range of uses. Following are a few material parameters presented in a tabular form :
