ptfe base tape film is used as sealing tape
The ptfe base film is a three-dimensional mesh-shaped film with no through-holes and a cross-microporous structure. This film can capture most dust particles, preventing dust from entering the film through the surface of the film.
People have long noticed that polytetrafluoroethylene (PTFE), which has the most outstanding comprehensive properties among polymer materials, has excellent high and low temperature properties, outstanding chemical stability, and good dielectric properties and hydrophobicity. An ideal membrane material for separating microparticles under some harsh conditions. However, the infusible and insoluble characteristics of PTFE have made the technology of manufacturing its microfiltration membrane difficult to solve for a long time, limiting its application and development. In the 1960s, DuPont first used The PTFE base tape membrane is produced by the uniaxial stretching method. Although its micropore size, porosity, and membrane strength are not suitable for use in microfilters, it has been widely used as a sealing tape in the future. In the mid-1970s, the United States successfully developed two-way stretching of PTFE. Microfiltration membranes were subsequently produced in Japan and Europe. However, so far only a limited number of companies produce and sell PTFE stretch membranes.
PTFE film manufacturer specializes in the production of PTFE base tape film. It has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
The ptfe biaxially stretched film produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely fine particles with a diameter of 0.1um-0.3um, The filtration level can reach H13-U16.
Products are widely used in various fields. The company has always implemented the purpose of “quality first, reputation first” to provide users with high-tech, high-quality, high-performance, and high-level products.
