Teflon tube tetrafluoroethylene specifications, Tianjin three (certified), PTFE

Teflon tube tetrafluoroethylene specifications, Tianjin three (certified), PTFE is provided by the three-Plastic Co., Ltd. of Tianjin. Plastic Co., Ltd. Tianjin three (www.tjzssj.com) is specialized in "nylon, PTFE, plastic, insulation material," the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Manager Zhou. Although carbon perfluorocarbon compounds - carbon bond and carbon - fluorine bond breaking require energy absorption 346.94 respectively and 484.88kJ / mol, but only PTFE depolymerization generate energy 171.38kJ 1mol tetrafluoroethylene. Therefore, when pyrolysis, polytetrafluoroethylene main depolymerization is tetrafluoroethylene. Polytetrafluoroethylene at 260,370 and 420 ℃ when the weight loss rate (%), respectively, and 1 × 10-4.4 × 10-3 9 × 10-2 per hour. Visible Teflon flange gasket tetrafluoroethane pad, PTFE long-term use 260 ℃. Due to the high temperature pyrolysis Shihai toxic byproducts phosgene and fluorine perfluoroisobutylene etc., so pay special attention to safety and to prevent PTFE expose to flame. PTFE sheet is divided into two kinds of molded panels and cutting boards, molded panels are made of PTFE resin at room temperature molding molding method, and then by sintering, cooling and made. Cutting boards by PTFE resin through compacts, sintering, peeling from. Heat temperature of 250 ℃, low temperature resistance -196 ℃, corrosion, weather, high lubricity, adhesion characteristics without PTFE plate except molten alkali metals, Teflon is almost free from any chemical reagents corrosion . For example, in concentrated sulfuric acid, nitric acid, hydrochloric tetrafluoroethylene plate tetrafluoroethylene seal, even in boiling aqua regia, no change in its weight and properties, it is almost insoluble in all solvents.
