[PTFE] Expansion joint related welding neck flange

Performance introduction of [PTFE] Expansion joint related welding neck flange: it does not melt at the temperature of 250 ℃ and does not become brittle at the ultra-low temperature of – 260 ℃. PTFE is so smooth that even ice can’t match it; Its insulation performance is particularly good. A thick film of newspaper is enough to withstand 1500V high voltage. PTFE maintains excellent mechanical properties in a wide temperature range of – 196 ~ 260 ℃. One of the characteristics of PTFE polymer is that it remains brittle at low temperature. Chemical corrosion resistance and weather resistance PTFE is hardly corroded by any chemical reagent except molten alkali metal. For example, when boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid or even aqua regia, its weight and properties do not change, and it is almost insoluble in all solvents. It is only slightly soluble in total alkanes (about 0.1g / 100g) above 300 ℃. PTFE is non hygroscopic, non combustible, extremely stable to oxygen and ultraviolet light, so it has excellent weather resistance.
