In order to extend the service life and increase the strength of the membrane, it is necessary to compound the polytetrafluoroethylene microporous membrane to various filter materials, such as various needle-punched felts, woven fabrics, glass fiber, etc.
Due to the non-stick characteristics of polytetrafluoroethylene itself, it requires very high requirements for membrane lamination technology. Currently, there are two lamination methods: glue lamination and thermal lamination.
① Glue composite is a relatively basic composite method, which has low composite strength, is easy to peel off, and has a 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 polytetrafluoroethylene microporous membrane, but has strict requirements for thermal composite technology.
Suzhou Membrane uses all imported raw materials and is a manufacturer specializing in the production and sales of polytetrafluoroethylene membrane materials.
