Product Q&A

Q:What is PTFE wire insulation?

PTFE wire is a type of hook-up that is insulated with polytetrafluoroethylene (PTFE). PTFE wire is often used in electrical applications thanks to its resistance to high temperatures and dielectric strength. It's also commonly referred to as PTFE wire, as PTFE is a very popular brand name for PTFE.

Q:What is the temperature rating of PTFE wire insulation?

Standard PTFE wire insulation is rated for a continuous operating temperature range of 60C to 200C. However, many specifications (like MIL-Spec M16878 Type E) and specialized wraps safely extend this maximum continuous rating up to 250C or 260C. The raw material itself does not melt until it reaches approximately 327C

Q:What is the difference between PTFE and ETFE wire insulation?

ETFE can endure temperatures from -185C to 150C (-300F to 300F), making it suitable for a wide range of environments. PTFE, however, boasts a broader range, withstanding temperatures from -260C to 260C (-460F to 500F), ideal for extreme conditions.

Q:Is PTFE good for high-temperature?

Yes, PTFE (polytetrafluoroethylene), widely known as PTFE, is highly heat resistant. It safely handles continuous temperatures up to 260C (500F) without degrading and has a high melting point of 327C (620F).
