Description
PFA (Perfluoroalkoxy) Extruded Films are polymer products known for their excellent thermal, electrical, and chemical-resistant properties. The defining characteristics of our PFA Extruded Films include impressive heat resistance, remarkable chemical stability, excellent electrical insulation properties, and superior weatherability. The films also possess non-stick and low-friction properties, making them invaluable in many industrial applications where reduction in surface friction is beneficial. They are resistant to almost all chemicals and solvents and can withstand high service temperatures up to 260 °C.
Alfa Chemistry offers high performance PFA extruded films in various grades including premium grade (PG) and economy grade (WG).
