Unsintered PTFE Film

 

The major application of unsintered PTFE film is for the insulation of wiring in aerospace and computer applications (e.g. hookup wire, coaxial cables). This application exploits the fact that unsintered PTFE film has excellent dielectric properties, specifically low group velocity dispersion, especially at high radio frequencies, making it suitable for use as an excellent insulator in connector assemblies and cables, and in printed circuit boards used at microwave frequencies. Combined with its high melting temperature, this makes it the material of choice as a high-performance substitute for the weaker, higher dispersion and lower-melting-point polyethylene commonly used in low-cost applications.

 

Unsintered PTFE film is a high-performance material that offers a range of benefits in a variety of industries. PTFE, also known as polytetrafluoroethylene, is a synthetic material that is widely recognized for its non-stick and low-friction properties. However, when it comes to unsintered PTFE film, there are a few key differences that set it apart from other PTFE materials.

 

 

 

 

· High temperature and chemical resistance

· Flammability resistivity

· High porosity results in superior dielectric properties

· High tensile strengths that support fast wrapping speeds

· Long joint free lengths

· RoHS and REACH compliant

 

 

 

· Wire and cable insulation for extreme chemical and thermal environments

· Binder tape in cable constructions and wire harnesses

· Dielectric material in coaxial cables

· Convoluted hose constructions

· And more
