The PTFE filling technology in China is all completed by processing and production enterprises. For the preparation of parts and components in the automobile and other industries, the modification methods toaster bag mainly include surface modification, filling modification and blending modification. The above-mentioned surface modification methods are mainly suitable for PTFE membranes. These fillers are required to withstand the sintering temperature of PTFE; they do not react with PTFE; In addition, it has a certain particle size and can improve some physical and chemical properties of PTFE. Thereby increasing its wettability, improving its surface activity, and easy to composite with other materials.
Filling modification Add fillers to PTFE to improve and overcome the shortcomings of PTFE. Surface deposition modification, immersing PTFE in a colloidal solution of some metal hydroxides, so [...]
