How can PTFE sheets be filled to withstand the high temperature of 300 degrees?

With the addition of PPL reinforced PTFE, a guest reported that the product of 8*3*4 remained unchanged in the center for 4 hours at 420 degrees and 250 degrees at the same time, which was a little hard for me to believe. In any case, in theory, if it exceeds 300 degrees, there should be toxic gas. Para-Polyphenylene Engineering Plastic Para-Polyphenylene Powder is a new polymer material with many excellent properties. When the polystyrene powder is burned in a high-temperature furnace, it begins to decompose at 530℃, and it has no melting point when burned at 450℃ for a long time, with little weight loss. Chemical corrosion resistance, so far, we have not found a solvent that can dissolve p-phenylene, and it has excellent self-lubricating performance, which is better than molybdenum sulfide and graphite. (1) technical index: 1, appearance: brownish red or dark brown powder 2, fineness: < 200 mesh 3, thermal weight loss: 400℃, 0.5h ≤4% (2) main use: 1, preparation of high-temperature ion exchange resin 2, preparation of organic semiconductor and photoconductor material 3. 2. Polystyrene engineering plastic This product is made of PTFE as matrix, filled with raw materials such as polystyrene powder, mixed molding, high temperature sintering and cooling. The comprehensive performance of this product is far better than that of PTFE products or seals made of PTFE filled with other raw materials 1-2 times or more. Especially in terms of high temperature resistance, it can be used at -269-+300℃ for a short time at 350℃. And widely used, such as chemical industry, printing and dyeing, compressors, valves and other industries. It is an ideal new oil-free self-lubricating engineering plastic with excellent comprehensive properties in domestic industry. Strong chemical resistance, strong acid, strong alkali, grease, detergent and organic solvent have no effect on him. 4. Excellent weather resistance. After being exposed to the atmosphere for many years, the surface and various properties remain unchanged. (3) Main uses: used for oil-free lubrication products and seals such as brakes, precision sealing rings, piston rings, guide rings, packing, gaskets, valve plates and shaft sleeves.
