Introduction

What is ETFE Fluoropolymer?

Peflon ETFE resin is a melt-processable ethylene-tetrafluoroethylene copolymer (ETFE, CAS 25038-71-5) available in powder, resin pellet and coating forms. It is customizable to any color and widely used across industry, energy, transportation, aerospace, electronics and medical sectors — wire & cable, tube, film and valve linings. Compared with PTFE, ETFE is tougher, lighter and more radiation-resistant while remaining melt-processable on conventional extrusion and injection equipment — see general ETFE property data. Its high light transmission and 20-year weatherability also make it the material behind ETFE architectural foil roofs.
Processing Methods

ETFE Resin Processing

Three primary processing routes — coating, fabric impregnation and additive blending — each leveraging ETFE’s property profile.
Coating

ETFE / PTFE Coating

Coated onto metal or fiberglass for non-stick and lubricating surfaces — cookware, pipe coating and non-stick equipment.

Impregnation

Impregnating High-Temperature Fabrics

Apply dispersion evenly, cure as directed and validate durability — produces technical fabrics with non-stick, chemical-resistant surfaces.

Additive

Anti-Drip Additive for Plastics

Blend into plastic, process uniformly and test for anti-drip performance — for flame-retardant engineering plastics.

FAQ

ETFE Resin — Frequently Asked Questions

How is ETFE different from PTFE and FEP?ETFE is a melt-processable ethylene-tetrafluoroethylene copolymer that is tougher, lighter and more abrasion- and radiation-resistant than PTFE, with higher tensile strength. Unlike PTFE it runs on standard extrusion and injection equipment, and it offers higher mechanical strength than FEP while keeping excellent chemical and weather resistance.
What forms does Peflon ETFE come in?Powder, resin pellet and coating grades — customizable to virtually any color. Pellets suit extrusion and injection molding; powder and coating grades suit rotolining, powder coating and fabric impregnation.
What is the service temperature range of ETFE?Peflon ETFE performs continuously from about −200 °C up to roughly 150–200 °C, keeping mechanical strength, flexibility and dielectric performance across that range.
How is ETFE processed?ETFE is melt-processable by extrusion (wire, tube, film), injection molding (connectors, valves) and coating. Typical melt temperatures are in the 300–340 °C range — much easier to process than PTFE, which is not melt-processable.
Is ETFE suitable for outdoor and architectural use?Yes. ETFE offers about 20-year weathering capability, high light transmission and a self-cleaning surface, which is why ETFE foil is used for stadium roofs, façades and greenhouses as well as solar back-sheets.
Is Peflon ETFE PFOA-free and compliant?Yes — Peflon ETFE is produced without PFOA and supports REACH, RoHS and SVHC documentation, with per-batch COA available on request.
