Description

Technical Parameters

Products Description

FEP is different from PTFE. It supports extrusion, injection molding, blow-molding and melt processing, and can be efficiently produced into complex products using ordinary plastic equipment.

It has a wide temperature range of -80 to 200 degrees Celsius, excellent chemical inertness, and also features V-0 flame retardancy, weather resistance and anti-aging properties, low friction and non-stick characteristics.

Its dielectric constant is stable at approximately 2.1, and its high-frequency insulation performance is outstanding. The products are semi-transparent and are mainly used in aviation cables and chemical anti-corrosion pipes.

FAQ

Q: Is FEP suitable for thermal shrinkable tube production?

A: Yes. FEP heat‑shrinkable tubes feature high‑temperature resistance, anti‑corrosion and insulation for wire harness protection.

Q: Could we use ordinary solvent to clean FEP surface?

A: Yes. Conventional ketones, alcohols can clean surface dirt without corroding FEP material.

Q: Could FEP be used for outdoor exposed cables?

A: Yes, good UV and ozone resistance, suitable for outdoor exposed cable sheaths.

Q: Could FEP pellets absorb moisture?

A: Low moisture absorption. Drying is generally not required, but avoid long‑term humid storage.
