PTFE safety instruction S24/25, that is, avoiding skin and eye contact; Hazard statement R4 1 indicates the risk of serious eye injury. When the heating temperature of PTFE is higher than 400℃, it will release toxic gases.
200 1 Nature, an authoritative scientific journal, published a research report published by the University of Toronto in Canada. According to the report, polytetrafluoroethylene (the main component of non-stick pan coating) and other similar coatings used to make non-stick pan and oven will degrade at high temperature, producing harmful compounds, including toxic long-term pollution, such as trifluoroacetate, and the decomposition rate is very slow. ?
Occupational disease prevention medicine also proves that the decomposition of PTFE has specific toxicity to kidneys, and the toxic effects of severe poisoning on central nervous system, respiratory system, cardiovascular system, liver and kidney can not be ignored.
Extended data:
Application of PTFE;
PTFE has excellent comprehensive properties, such as high temperature resistance, corrosion resistance, non-stick, self-lubrication, excellent dielectric properties and low friction coefficient. Used as engineering plastics, it can be made into PTFE pipes, rods, belts, plates, films and so on. , generally used in corrosion-resistant pipes, containers, pumps, valves, radar, high-frequency communication equipment, radio equipment, etc.
By adding any filler that can withstand the sintering temperature of PTFE, the mechanical properties can be greatly improved while maintaining other excellent properties of PTFE. Filled with glass fiber, metal, metallized oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL…, etc. Wear resistance and ultimate PV value can be increased by 1000 times.
PTFE compression packing is a good dynamic sealing material, which is woven from expanded ptef. It has excellent properties such as low friction coefficient, wear resistance, chemical corrosion resistance, good sealing performance, no hydrolysis and no hardening. Gasket sealing and lubricating materials used in various media, as well as electrical insulation parts, capacitor media, wire insulation, electrical instrument insulation, etc. Used for various frequencies.
