Waterproof and breathable PTFE bubble point membrane material has high porosity, uniform pore size distribution, breathability, small friction coefficient and minimal adsorption. Excellent stretching technology…

PTFE bubble point membrane has excellent waterproof performance and is tightly wrapped to protect the building from water vapor and rainwater erosion. Effectively ensure the insulation effect and durability of …

As an environmentally friendly material, PTFE bubble point membrane is applied to the surface of various filter materials through composite processing. This film is laminated on various fabrics and substrates u…

In the PTFE bubble film forming process, the two-way stretching or stretching processing method is often used abroad. PTFE can be stretched between normal temperature and 327°C, that is, the stretching below th…

PTFE bubble point film is laminated with stretched and expanded polytetrafluoroethylene film and polyester and other base materials. Before lamination, the polytetrafluoroethylene film and base material are tes…

PTFE bubble-point membrane has excellent chemical stability, can withstand strong acid and alkali corrosion, and has a wide temperature tolerance. Therefore, PTFE has great advantages compared with other filter…

The polytetrafluoroethylene bubble point membrane itself has countless interconnected micropores. The pore size is very small (about 0.01~10 microns) and can only pass through water vapor molecules with a parti…

There are two main production processes for polytetrafluoroethylene bubble-dot film: blow molding and casting. The main production process flow is: the dehumidified and dried raw materials and calcium carbonate…

Due to the excellent properties of polytetrafluoroethylene, people have developed polytetrafluoroethylene-coated filter media using polytetrafluoroethylene films. The membrane-coated filter material uses a laye…
