    PTFE gasket characteristic

    Polytetrafluoroethylene (PTFE) as a sealing material has many applications. Because of its high corrosion resistance, stable physical performance, high and low temperature resistance, it has achieved good sealing performance, and has been widely used in petroleum, chemical, pharmaceutical, electric power, iron and steel industry. Applicable media include water, oil, acid solution, alkali solution and almost all chemical components.
    Soft PTFE is refined. Durable, reliable sealing performance; PTFE itself has the best corrosion resistance and ageing resistance, after special processing has a good creep resistance and cold flow resistance; can be used in a wide temperature range for a long time; soft and easy to cut, through mechanical or manual cutting, easy to install.

    Sealing PTFE gasket

    1) Raw material preparation; Ingredients: pure F4 products, raw material F4 fine resin, mashing, sieving
    2) Mould preparation: clean with alcohol, no rust and no attachment in the die
    3) Weighing, according to the formula G = PV(where G is the feeding quantity and P is the density of prefabricated products (2.18g/cm3) V is the volume of the product) weigh it.
    4) Feeding: The F4 resin is evenly distributed on the whole pressing surface.
    5) Preforming (pressing): Calculate the gauge pressure of the press according to the formula, and set the gauge pressure of the press. Suppress
    6) Demoulding and trimming: Remove semi-finished products from the die and trim their surface to make the surface smooth and the edge neat. Prepare to shape.
    7) Sintering: Slowly put semi-finished products into the sintering furnace, put in the appropriate quantity, heat up about 390 degrees for one hour, then heat preservation for another hour, about one hour after forming, begin to cool down, about four hours later, reach the indoor temperature, carry out finished products out of the furnace, and finally complete the finalization.

    Expansion PTFE board

    The high sealing gasket made of PTFE extruded does not contain any binder and additives. It has strong resistance to chemical corrosion; special design makes cushion plate have strong resistance to creep and cold flow, so as to ensure the stability of bolt tightening force during sealing process; it has good flexibility, compression resilience, high and low temperature resistance, non-aging, self-lubrication, etc; it is soft and easy to cut, and can be cut by machine or manual, so it is easy to install; The service life of flange is greatly prolonged without special increase of compression force. Make up for irregular sealing surface, reliable sealing performance, especially excellent gas sealing performance.

    Appearance color: white.Applicable Temperature: - 180 ~250
    Applicable media: PH 0-14Routine size: 1500mm*1500mm thick 1.5-3mm

    Users can buy the whole sheet, cut the flange into gaskets according to the caliber of their own equipment, or put forward their own requirements by the supplier preform.

    Modified PTFE gasket sheet

    Inorganic matter is used as filler, which is evenly dissolved into PTFE raw material and processed.

    Compared with pure PTFE, modified PTFE has the advantages of high compressive strength, wear resistance, good thermal conductivity and reduced thermal expansion. The internal multi-directional fiber structure makes the product have strong chemical corrosion resistance, no cold flow and creep phenomena, and can maintain a reliable seal for a long time.

    The pad filler is inorganic, does not contain any binder, does not adhere to the sealing surface, and is repeatedly used on the same sealing surface. Easy to cut, mechanical or manual cutting, easy to install. There is no aging problem and it can be preserved for a long time.

    Appearance color: white or blueApplicable Temperature: - 180 ~250
    Applicable media: PH 0-14Routine size: 1524mm*1524mm thick 1.5-8mm

    Users can buy the whole sheet, cut the flange into gaskets according to the caliber of their own equipment, or put forward their own requirements by the supplier preform.

    Expansion sealing tape

    The performance of the product itself is the same as that of the expanded PTFE sealing gasket plate, which is more convenient to use. When in use, clean and dry the sealing surface, select the appropriate width of the sealing tape, cut the required length, ensure that the two ends can cross after a circle, tear off the viscose protective paper, and paste the sealing tape on the sealing surface, then assemble. Only a small bolt tightening force is needed to form a good seal.

    The utility model is a non-metallic composite soft gasket, which is composed of a covering cover and an embedded body. The coating material is polytetrafluoroethylene, and the insert body is asbestos-free gasket or other non-metallic gasket without metal reinforcement. The gasket has excellent corrosion resistance and good compression resilience. It is mainly suitable for flange connection of flat or sudden steel pipe.

    Applicable Temperature: - 100 ~250

    Applicable media: PH 0-14

    Routine size: flange gaskets in line with national standards of various industries and products of American and European standards can be provided.

    Tooth waveform composite cushion

    The surface of metal gasket is machined into concentric rings with V-shaped teeth or waveforms, which can form many line contacts with the surface of flange with pressure difference space, so the sealing is reliable and the service life is long. Compared with ordinary metal flat gaskets, this kind of gasket requires less pre-tightening force.

    In general use, in order to protect the tooth shape, PTFE with thickness of 0.5mm should be pasted on both sides of the metal gasket, and the requirement for the smoothness of the sealing surface can be reduced. It is widely used in flange joints of chemical plants, power plants and nuclear power plants.

    Winding pad

    PTFE winding gasket is a semi-metallic flat gasket made of V-shaped or W-shaped thin steel strip spirally wound with filler PTFE. By changing the material combination of gaskets, the problem of chemical corrosion of gaskets by various media can be solved.

    The gasket has good compression resilience, multi-channel sealing and certain self-tightening function, which can partly eliminate the influence of pressure, temperature change and mechanical vibration. Non-bonded flange surface, easy to repair and replace. It can keep its excellent sealing performance under high temperature, low temperature, high vacuum, impact vibration and other cyclic and harsh conditions. It is suitable for sealing parts with severe temperature and pressure alternation. It is a static sealing element at flange joints of pipes, valves, pumps, heat exchangers, towers, manholes, hand holes and so on.

    The density (hardness) of the winding gasket can be changed by changing the tension force of the winding steel strip to meet the needs of various application parts. It is widely used in petrochemical, mechanical, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace industries
