The preparation method of ptfe composite materials is to naturally roll the expanded polytetrafluoroethylene film onto a roller, and then take it out to cool down naturally after heat treatment. The disadvantage of this method is that the metal roller cools down slowly, while the composite material cools down too quickly. During the cooling process, the air is filled into the PTFE composite material and then contacts the metal roller to expand due to heat. The composite material will bulge on the roller, resulting in a poor appearance of the composite material.
If the oven is used to cool down slowly, it will take a long time and a lot of energy, which is not conducive to sustainable production.
We are a high-tech enterprise specializing in the research and development, production and sales of polytetrafluoroethylene microporous membranes. We have a full set of advanced production equipment and testing instruments, and a complete pre-sales, sales and after-sales service system.
