We know that the performance of the seal on the whole machine equipment efficiency and performance have a great impact. Modified PTFE gasket with corrosion resistance, aging resistance, low coefficient of friction and non-sticky, wide temperature range, good elasticity characteristics make it very suitable for use in the manufacture of high corrosion resistance requirements, the use of temperature higher than 100 ℃ seal Pieces. Modified PTFE gasket for most of the chemicals and solvents, showing inert, strong acid and alkali resistance, water and a variety of organic solvents, the use of working temperature up to 250 ℃. Has a good mechanical toughness; even if the temperature dropped to -196 ℃, can also maintain a 5% elongation. Modified PTFE gasket for a variety of needs anti-acid and alkali and organic solvent conditions, sealing, high lubrication non-stick, electrical insulation and good anti-aging, temperature span (at 250 ℃ to - 180 ℃ temperature long-term work.
Modified PTFE gasket does not contain any binder and additives. Has a strong anti-chemical corrosion performance, specially designed to have a strong anti-creep cold flow performance, so as to ensure the sealing process of tightening force of the bolt to maintain stability; has a good flexibility, compression resilience, high Low temperature, no aging, self-lubricating, etc .; soft and easy to cut, can be cut by mechanical or manual, easy to install; has a unique ability to adapt to the molding, without special increase in compression, greatly extend the service life of the flange. To make up the sealing surface of the irregular, reliable sealing performance, especially gas seal performance.
Applicable media, including water, oil, acid solution, alkaline solution and almost all of the chemical composition. Applicable to the temperature, pressure alternating intense sealing parts, is the pipeline, valves, pumps, heat exchangers, towers, manholes, hand holes and other flange connection of the static seal components. As the rubber, glass, metal alloys and other materials in the corrosion-resistant defects, it is difficult to meet the harsh conditions of temperature, pressure and chemical medium coexistence of the environment, the resulting loss is quite amazing. Modified PTFE gasket with its excellent corrosion resistance, has become the oil, chemicals, textiles and other industries the main corrosion-resistant materials. In food, paper, medicine, electronics and machinery and other industrial and marine operations have a wide range of applications. Application of the corrosive gas in the delivery of the pipe, exhaust pipe, steam pipe, rolling mill high pressure tubing, aircraft hydraulic system and cold pressure system of high and low pressure pipes, distillation tower, heat exchanger, kettle, , Valves and other chemical equipment. At present, modified PTFE gasket has been in the chemical industry, machinery, electronics, electrical appliances, military, aerospace, environmental protection and bridges and other areas of the national economy played a pivotal role.
