PTFE board (also called Teflon plate ， Teflon plate ， Teflon plate ）There are two types: molding and turning, Molded plate Is created by teflon Resin is used at room temperature Molding method It is formed, sintered and cooled. teflon Turning plate It 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 and other excellent characteristics.

1. Purpose:

Polytetrafluoroethylene plate is suitable for gaskets, seals and lubricating materials working in various corrosive media at - 180 ° C -+250 * C temperature, and also for making electrical insulation parts used at various frequencies.

2. Appearance:

(1) The color of the plate is the natural color of the resin.

(2) The texture shall be uniform, the appearance shall be flat, and no crack, bubble, delamination, mechanical damage, knife mark and other defects are allowed.

(3) Light cloud patches are allowed.

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