Polyzole™

polyzole-filament

Polyzole™
Polyzole™ is a thermo-resistant synthetic material. It is available in pulp, staple fiber, and filament form. Polyzole™ does not melt and is available in two forms: UV stabilized & natural. Polyzole™ has excellent “tribo” properties. Current applications include protective apparel, break pads and hot-gas filtration.
