F4 plastic washer material

F4 plastic washer material 1.excellent chemical properties,acid and alkali resistant 2.wide working temperature range F4 plastic washer Material

 Characteristics:F4 / PTFE gasket is made of suspension PTFE. Compared with other plastics, it has better corrosion-resistance and excellent heat-resistance. It is now widely used as sealing material.Usage:It is usually used for corrosion-resistance under -180 - 200°C, and sealing parts in ordinary electric property conditions.Main technical indicator: 1) Apparent density: 2.10 ~ 2.30g/cm32) Tensile strength: ≥15.0Mpa3) Ultimate elongation: ≥150%
