PTFE microporous membrane is adopted to cover the surface of base material. The film thickness can be chosen within a range for proper permeability and filtration precision. The width of membraned material is 2.2m to its maximum.
The imported quality high-temperature heating roller has a very narrow temperature tolerance of plus minus1℃, so the deformation of roller surface is extremely tiny under high temperature operation, which ensures the fastness and evenness of PTFE membrane on to the base material.
