Brief description

ptfe round washer


Characteristics:

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/cm3

2) Tensile strength: ≥15.0Mpa

3) Ultimate elongation: ≥150%
