At present, there are two methods of compounding three-layer and five-layer composite materials: glue compounding and thermal compounding.
1. Glue lamination is a relatively elementary lamination method, which has low composite strength, is easy to peel off, and has a short lifespan. Due to the penetration of glue, it has poor air permeability and is not suitable for dust 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.
