E.T.F.E

Ethylene Tetra Fluoro Ethylene

Du Pont first introduced this fluorplastic in 1972 and is the first fluoroplastic than can be reinforced and not just filled with glass fibre.

E.T.F.E can be best described as a rugged thermoplastic with an outstanding balance of properties. Mechanically, it is tough and has medium stiffness, excellent flex life, impact and abrasion resistance. It has a continuous working temperature of 150°C however intermittent use to 200°C is dependant on load, exposure time and environment.

E.T.F.E is inert to most solvents and chemicals and is also weather and UV resistant. It has excellent resistance to high-energy radiation and microwaves.

Electrically, E.T.F.E is an excellent insulator combining high dielectric strength and surface resistivity with a dielectric constant of 2.6 and a dissipation factor of 0.0006.

ETFE can be characterised by the following properties:

Wide temperature range of -190°C to +150°C
Good mechanical strength
Good electrical properties
High chemical resistance
High resistance to ageing
High resistance to weathering
Excellent low coefficient of friction

Fields of application: chemical pump bearings, gears, laboratory consumables, tower packings, and pump components.
