PTFE composite materials, also known as three-layer and five-layer composite materials, are based on PTFE resin and exhibit good wear resistance by adding organic or inorganic wear-reducing components and anti-wear reinforcing components.
Wear-resistant composite materials using polymers as a matrix have a series of excellent properties such as friction-reducing self-lubrication, wear resistance, corrosion resistance, shock absorption, noise reduction, low relative density, enhanced strength and easy processing. Therefore, as other Substitute products or replacement products of materials have become more and more widely used.
?At present, there are two methods of compounding three-layer and five-layer composite materials: glue compounding and thermal compounding.
1. Glue composite is a relatively basic composite method with low composite strength, easy to peel off, and short service life. Due to the penetration of glue, it has poor air permeability and is not suitable for cleaning, which weakens the superior performance of PTFE.
?2. Thermal composite advanced composite method completely maintains the superior performance of PTFE film, but has strict requirements for thermal composite technology.
