How to improve the purity and wear resistance of PTFE gaskets

PTFE gaskets are flat gaskets, V-shaped gaskets, piston rings, ball valve gaskets made of PTFE rods, tubes, and plates by mechanical turning or cutting. They have excellent corrosion resistance, anti-aging and non-conductivity. characteristic. So, how to improve the purity and wear resistance of PTFE gaskets?

PTFE gasket is a kind of wear-resistant material, simple PTFE gasket is softer than, in order to increase the wear resistance, many manufacturers have opened various formulas as additives for modification, generally speaking, filling PTFE gasket becomes such a material. 300 rotation speed is not high, of course, friction will also cause the temperature of the wear-resistant material to rise, and then the material expands, resulting in cylinder jams, ups and downs in sealing performance, etc. Pneumatic membrane lined PTFE single-seat control valve is the implementation unit of automatic instrumentation.

The PTFE gasket is made of pneumatic membrane, passing through a single seat lined with fluoroplastic valve. Due to the high-pressure injection process of the valve medium, the lining has the ability to resist corrosion and anti-aging polyfluoroethylene. At the same time, it also accepts PTFE gasket bellows to seal, so that the valve can be used in the chemical, kerosene, medicine, electric power and other industries. Process control of alkaline fluorine medium and toxic and volatile gases.

The importance of improving the purity of PTFE gaskets

PTFE gasket, also known as polytetrafluoroethylene sheath, is a non-metallic gasket, generally composed of two parts, covering layer and insert. The cladding layer mainly exhibits corrosion resistance and is generally made of polytetrafluoroethylene. It can be made into a variety of circular and complex geometric gaskets. The graphite cut gasket can also be made into a package form on the outer and inner rings, and it is easy to install and disassemble and not easy to damage. Compared with other plastics, it has been widely used as a sealing material and filler material, with chemical resistance and excellent temperature resistance.

Due to the high purity of the product, it has outstanding corrosion resistance, can accept high temperature and low temperature, outstanding compression toughness and high strength, suitable for low pressure part sealing, and can prevent electrochemical corrosion. PTFE gasket is a truly advanced and common material. It has excellent functions such as creep resistance, cold resistance, low temperature, no pollution, easy installation, and detachable. Under a very small preload, it can accept considerable internal pressure even under pressure changes. It is very suitable for rough or worn and brittle glass surface flanges, and temperature changes. We can produce the required gaskets for users according to the customer’s selection.
