Porous PTFE

Porous Polytetraflon^TM PTFE can be manufactured thanks to the use of a special pressing/sintering process. The size of the pores is statistically distributed and ranges from 1 to 20 μm. The average pore diameter can be set at approximately 2 to 10 μm depending on the material and degree of compaction. This combination of higher porosity and mechanical strength permits technically self-supporting solutions and therefore offers a clear advantage over competitor products, which often can only be used with support. Films and components made of porous Polytetraflon^TM PTFE combine a high degree of air permeability and water resistance, and are therefore optimally suited for venting and media separation in filters.

Polytetraflon™-PTFE

Lowest friction coefficient of any polymer

Exceptionally large operating temperate range: -260°C to +260°C

Very good sliding characteristics - self-lubricating effect

No water absorption, water repellent

Anti-adhesive

Almost universal chemical resistance

Good electrical and dielectric properties

Resistance to superheated steam

Light, weather and UV radiation resistant

self extinguishing in acc. with UL 94 V-0

Physiologically harmless
