PTFE Plate (also called PTFE plate, PTFE plate, PTFE plate) is divided into two kinds of molding and turning. The molding plate is made of polytetrafluoroethylene resin by molding at room temperature, and then by sintering and cooling. Polytetrafluoroethylene turning plate is made of polytetrafluoroethylene resin by pressing, sintering and rotary cutting. Its products are widely used and have excellent comprehensive properties: high and low temperature resistance (- 192 ℃ - 260 ℃), corrosion resistance (strong acid, strong alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, non adhesion, non-toxic and other excellent characteristics.

1. purpose:

Polytetrafluoroethylene plate is applicable to the gasket, seal and lubricating materials working in various corrosive media at the temperature of - 180 ° C - + 250 * C. It is also made into electrical insulation parts used in various frequencies.

2. appearance:

(1) The color of the plate is resin.

(2) It shall be uniform in texture, smooth in appearance, and free of cracks, bubbles, delamination, mechanical damage, knife marks and other defects.

(3) It is allowed to have light and micro cloud like tightness.

(4) No more than 1 non-metallic impurity with diameter of 0.1-0.5mm and no more than 1 non-metallic impurity with diameter of 0.5-2mm are allowed on the area of 10x10cm2.

Its emergence has solved many problems in the fields of chemical industry, petroleum, pharmaceutical and so on. Polytetrafluoroethylene seal, washer, gasket, polytetrafluoroethylene seal and seal washer are made by molding with suspension polytetrafluoroethylene resin. Compared with other plastics, polytetrafluoroethylene has the characteristics of chemical corrosion resistance. It has been widely used as sealing material and filling material.
