Due to the unique properties of PTFE, PTFE gaskets are widely used in industries such as chemical, petroleum, textile, food, paper, medicine, electronics and machinery, and marine operations.
1. Excellent anti-corrosion performance
Due to the defects in corrosion resistance of rubber, glass, metal alloys and other materials, it is difficult to meet the harsh environment of coexistence of severe temperature, pressure and chemical media, and the resulting losses are quite alarming. With its excellent corrosion resistance, Bird Teflon material has also become the main corrosion-resistant material in petroleum, chemical, textile and other industries. Its specific applications include: conveying pipes for conveying corrosive gases, exhaust pipes, steam pipes, high-pressure oil pipes for rolling mills, high, medium and low pressure pipes for aircraft hydraulic systems and cold pressure systems, rectification towers, heat exchangers, kettles, towers, and tanks Lining, valves and other chemical equipment.
PTFE gasket material has the characteristics of corrosion resistance, aging resistance, low friction coefficient and non-stickiness, wide temperature range, and good elasticity, which makes it very suitable for the manufacture of seals with high corrosion resistance requirements and use temperatures exceeding 100 ° C. The performance of the seals has a great impact on the efficiency and performance of the entire machine. Such as seals for groove flanges of machines, heat exchangers, high-pressure vessels, large-diameter vessels, valves, pumps, seals for glass reactors, flat flanges, large-diameter flanges, shafts, piston rods, valve rods, Rod seals and so on.
2. Low friction performance
Because the friction part of some equipment should not be lubricated with oil, for example, when the lubricating grease will be dissolved by the solvent and fail, or products in the paper, pharmaceutical, food, textile and other industrial fields need to avoid oil contamination, this makes the filled PTFE material The most ideal material for mechanical equipment parts without oil lubrication (direct load). This is because the coefficient of friction of Bird sealing materials is the lowest among known solid materials. Its specific uses include bearings for chemical equipment, paper machinery, and agricultural machinery, used as piston rings, machine tool guides, and guide rings; in civil engineering, it is widely used as bridges, tunnels, steel truss, large chemical pipelines, storage tanks Support slider, as well as bridge support and bridge swivel.
