Full Density Ptfe Skived Film

 

Full density ptfe skived film is consist of suspension PTFE resin by moulding, sintering, cooling into blank, then cutting and rolling into film. PTFE film has excellent dielectric properties, ageing-resistance, corrosion resistance, flame resistance, high lubrication and excellent chemical corrosion resistance.

 

Description:

Full Density Ptfe Skived Film with a high temp, silicone adhesive. Used in electrical applications such as harness/coil wraps and separators, transformers and slot liners where good insulation and heat resistance are required. Also used in mechanical applications such as heat sealing bars and jaws, labeling machine pressure pads, chute liners, anti-friction devices, bearings, forming dies, aircraft mold release and guide rails where high temperature, maximum slip and lubricity are required. High elongation permits tight wrapping; conforms to sharp bends/irregular surfaces.

Full Density Ptfe Skived Film is a high density, TENSILIZED skived PTFE film which provides higher tensile strength, lower elongation and higher dielectric strength than regular skived film (primarily used for electrical applications listed above and for roll protection in flat die extrusion) and meets spec AA-59474 Type-1, Superseding 23594C Type 1. 3" plastic core.

FAQ:

 

Customer: What is PTFE wire insulation?

Foreverseal: Polytetrafluoroethylene (PTFE) is a fluorocarbon polymer insulation material that allows wiring systems to be used and operated in the most demanding of environments. PTFE is resistant to lubricants and fuels, very flexible, plus it has excellent thermal and electrical properties.

 

Customer: Is PTFE material used as an insulator around electrical wiring?

Foreverseal: The benefits of PTFE as an electrical insulator are well known. The high dielectric strength and breakdown voltage of PTFE allows it to be used in applications where standard insulation materials would fail.

 

Customer: What's the delivery time?

Foreverseal: 30 days after getting prepayment
