What is PTFE film made of?
PTFE film is made of pure PTFE resin.
What are the outstanding performance characteristics of PTFE film?
PTFE film has ultra-low coefficient of friction and is self-lubricating. PTFE film can work at temperatures up to 500°F. PTFE film has excellent chemical resistance. PTFE film is an excellent insulator. PTFE film has ultra-high purity.
What are the limitations of PTFE film?
PTFE film has low compressive and tensile strength.
What are some general application scenarios for PTFE film?
Capacitor films, cable harnesses, gaskets, electrical insulation parts, PCBs, flexible circuits, cap linings, plungers, plugs, protective linings, gaskets, diaphragms, semiconductor processing parts, expansion joint linings and sleeves, fuel cell seals and separators Panels, solar panel (photovoltaic) modules and surface protection liners.
Why is it necessary to develop surface modification strategies for PTFE film?
PTFE film has poor wettability and adhesion with other materials, which hinders its application in certain circumstances. Surface modification strategies are needed to customize its surface properties for specific applications.
How can the hydrophilicity of PTFE film be enhanced?
The hydrophilicity of PTFE film can be greatly enhanced by pretreating it with remote argon plasma, grafting acrylic acid (AAc) onto the surface, and then exposing it to oxygen to generate peroxides.
What is an electret diaphragm and how is PTFE film used in its preparation?
An electret diaphragm is a dielectric material that can capture quasi-permanent space charge caused by external charging. A porous PTFE film is used as a substrate to prepare electret diaphragms for loudspeakers.
What are the advantages of using a PTFE/COC composite film for electret diaphragms?
The composite film has improved advantageous properties, including improved charge storage capacity, adhesion to the electrode layer, high charge storage stability, and improved elastic modulus and stress. This makes it suitable for manufacturing flexible electret diaphragms for loudspeakers.
What are the research applications of PTFE film?
PTFE film is widely used in many fields due to its excellent volume characteristics, such as low friction coefficient, high stability to heat and chemical reagents, and high electrical resistance. It is used in applications that require high temperature and chemical resistance materials, such as capacitor films, cable harnesses, gaskets, electrical insulation parts, and more.
