PLASTICS

POLYTETRAFLUORETHYLENE PTFE:

QUALITIES:

Thermal resistance
Thermal PTFE resins resist temperatures between -65ºC and 260ºC.
Anti-adherence
Nothing adheres to the surface, unless a special treatment is given.
Mechanization
Its low hardness, 5 - 70 Shore, allows easy mechanization.
Thermal insulator
It has exceptional insulating characteristics specially as a dielectric material, which stay constant within a very wide range of frequencies.
Practically absolute chemical resistance

PTFE WITH SPECIAL-PURPOSE CHARGES:

Fiber of glass (25%) Carbon (25%)
Carbon (25%) + Graphite (2%)
Graphite (10%)
Bronze (60%)
Stainless steel (50%)
Ceramics (15%)

SANDWICH TYPE GASKET:

The sandwich type gasket, covered with PTFE, combines the chemical resistance of PTFE with the mechanical resistance and the elasticity of the material inserted:

Cardboard, graphite or rubber.

VITON OR SILICONE TORIC GASKET ENCAPSULATED IN F.E.P. :

Gasket with chemical resistance specially indicated for the food industry.

PTFE GASKET WITH PERFORATED STEEL CORE

Gasket with a 100% chemical resistance, zero contamination and without restrictions for use in the food industry.
