PTFE biaxially stretched membrane 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.

In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.

Under the tensile force of the PTFE biaxially stretched film, the fibrils are pulled out from the PTFE resin particles. As the force increases, the length of the fibrils increases and the film becomes thinner.

When the fibril becomes no longer extensible, the force is transferred to the middle area of ​​the base tape in turn, and then the middle part of the base tape is stretched.

Therefore, the biaxially stretched film tends to be thin on both sides and thick in the middle.

High temperature stretching is easier than low temperature stretching to make the film thinner.

In the transverse stretching direction of the film, in the area at the same distance from the edge, the pore size of the film stretched at high temperature is generally larger; at the same stretching temperature, the pore size in the area closer to the edge of the film is also generally larger than middle area.

Have advanced PTFE film production lines and composite production lines.

The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
