PTFE backup ring -excellent electrical -good non-adhesive properties -high chemical stability&temperature resistance PTFE backup ringDF-101 has excellent electrical and non-adhesive properties, high temperature resistance (from -250 to +260 ) and high chemical stability. Due to its high elasticity, DF-101 has a good seal effect.Typical Application Being adopted in the electric or electronic industry's insulation, foodstuff or chemical machinery's adhesive resistance, and as static sealing parts or corrosion resistant gaskets.
