Three-layer and five-layer composite materials can also be referred to as ptfe, and are generally called “non-stick coatings” or “easy-to-clean materials”.
This material is acid-resistant, alkali-resistant, and resistant to various organic solvents. It is almost insoluble in all solvents.
At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and its friction coefficient is extremely low, so people often combine ptfe with other materials to obtain ptfe composite materials.
The three-layer and five-layer composite material is a composite material that uses a special process to compound the PTFE film on the surface of the clothing fabric, which is waterproof, breathable, windproof and warm.
Compared with other polymers, PTFE composites have unique advantages, but there are also some shortcomings, such as poor mechanical processing performance, large linear expansion coefficient, poor creep resistance, and easy cold flow. , poor wear resistance, difficulty in molding and secondary processing, etc., which limits its application.
