PTFE VIRGIN

PTFE is as a high performance product with many practical applications. Famous for its extremely good slip characteristics, it also provides the combined advantage of exceptional thermal, electrical and chemical properties that supersede its mechanical features.

A fluorocarbon solid with high-molecular-weight composed wholly of carbon and fluorine that is diverse in its application.

Widely used as non-stick coating for fry pans and cook ware, PTFE is most familiar to many people as Teflon® brand by DuPont, the originators of PTFE compound. E-Plas provides the highest quality PTFE range through top European manufacturer Guarniflon, Italy.

It is used to make pipes, containers and other containment devices where corrosive or reactive chemicals are present (except for alkali and hydrofluoric acid) because of its non-reactive properties imparted to some degree by the strength of carbon–fluorine bonds.

PTFE used for its lubricant property reduces friction, wear and energy consumption of machinery.

Optical radiometry applications include PTFE sheets for measuring heads in spectroradiometers and broadband radiometers. PTFE is able to diffuse transmitting light extremely well. Its optical properties remain constant from UV down to near infrared wavelengths.

It is used as a graft material in surgical interventions in particular for treating vascular disease.

PTFE tubes are used in gas-gas heat and gas cleaning applications.

 

Virgin / Unfilled PTFE is the most common form or standard grade and has some unique features which, apart from its good slip characteristics and as a high performance plastic provides the advantages of excellent thermal, electrical and chemical properties. It is less noted for its mechanical properties.

It is hydroscopic, that is it cannot be made wet or absorb water even from substances that contain water.

 

It has one of the lowest coefficients of friction and is chemically inert.

It can handle harsh chemical exposure to extreme conditions and climate thanks to its thermal stability.This also means it weathers well and resist stress cracking.

 

It has diversity. Being chemically inert and non-toxic (approved for food applications) it is perfect for applications as polarised as food preparation to medical application as used for surgical grafts.

It is also easily machined however has poor mechanical strength.
