PTFE film bonding technology

After several years of research, China has completed a production line with an annual production capacity of 3 million meters and stretched PTFE microporous membrane film. The principle of equipment design and main product specifications are comparable to those of Gore Corporation in the United States. In the halogen lamp heating, laser thickness measurement, computer Drag and control technology and other aspects have been innovative. For PTFE film surface smooth, low polarity, bonding difficulties, etc.

The first is the development of polyester hot melt adhesives and low temperature silicone adhesives, so that the low temperature flexibility of laminated fabrics is better than the United States Gore's products;

> The second is the use of corona radiation treatment PTFE film to improve its adhesive properties. It was put into operation at the end of 1997. The products have been used in thermal protective clothing in the extreme cold and cold regions of the armed forces, multi-functional clothing of the Ministry of Public Security, an Antarctic survey service, offshore oil field work clothes, and navy sea clothes. The performance comparison between the products and the U.S. uniform clothing is shown in Table 7.
