High quality ptfe washer ptfe gasket shim
Compared with other plastics, ptfe washers have more better corrosion-resistance and excellent heat-resistance.
They are now widely used as sealing material.
They are usually used as corrosion-resistance under -180 ~ +200°C, and sealing parts in ordinary electric property conditions.
