To what extent is polytetrafluoroethylene anti-corrosion?

The birth of steel lined PTFE is to make metal fittings have strong stiffness. In order to make straight pipes and fittings have both the strength and stiffness of metal and the excellent corrosion resistance of plastic, steel lined PTFE straight pipes and fittings are made of metal materials (seamless steel pipes of 20 # carbon steel, steel flanges or castings). The anti-corrosion material is lined with polytetrafluoroethylene (F4) of corresponding thickness. The straight pipe with a nominal diameter of DN300mm is lined using seamless steel pipe extrusion lining F4 pipe method All fittings of DN300mm F4 straight pipes, elbows, tees, tees, and reducers are formed by molding and sintering process. The material characteristics of polytetrafluoroethylene plastic include excellent chemical stability, high heat and cold resistance, low friction coefficient, good self-lubricating properties, but low mechanical properties, poor fluidity, and large thermal expansion. Its temperature resistance and corrosion resistance are unmatched by other materials, and it is known as the king of plastics.

Corrosion and high temperature resistance: In strong corrosive media such as acid and alkali, it can meet the use of up to 200 ℃. Positive and negative pressure resistance: -0.09~2.5MPa, complete specifications: DN25~DN600mm, pipe fittings: elbows, tees, tees, reducers, instrument joints, sight glasses, feeding pipes, etc., all using mold pressing or isostatic pressing processing technology.

Polyethylene rods can be processed to produce liners, seals, lining partitions, scrapers, guide rails, as well as electrical insulation components and bridge support sliders used at various frequencies. At present, various universal bars (push rods, molded rods, etc.) can be produced domestically. Good corrosion resistance and dielectric properties, aging resistance, suitable for long-term use in environments ranging from 180 to 250 ℃, with low friction coefficient. Electrical insulation components used at various frequencies. Sealing gasket anti stick materials and lubricating materials in various corrosive media. Polytetrafluoroethylene film, turning film, directional film, semi directional film, color semi directional film, color film has multiple colors such as red, yellow, and green. Polytetrafluoroethylene film (PTFE film) has excellent characteristics such as high tensile strength, good insulation, and non adhesion. Insulation materials for capacitors, insulation layers for special cables, insulation for electrical instruments, non stick tapes, sealing tapes, and can also be used for insulation of motors and transformers. High grade soluble polytetrafluoroethylene is a type of polytetrafluoroethylene (Dongguan Teflon) with perfluoroalkyl ether, which retains the excellent properties of polytetrafluoroethylene resin and has good thermoplastic properties. It can be melted and processed like general thermoplastic plastics. High grade meltable polytetrachloroethylene is mainly used in industries such as electronics, semiconductors, and chemicals.
