Oil Heat Shrink Tube
High temperature, high quality and oil resistance soft rubber heat shrinkable tube is made of cross-inking of special polymers by irradiation. It has excellent oil resistance (aviation oil, fuel oil, hydraulic oil, lubrication oil, etc.) performance.
·Features
·Shrink ratio 2:1
·Excellent oil resistance, heat resistance
·Reliable guarantee of coating avoid from abrasion or mechanical damage from objects
·Good low temperature flexibility, good flame resistance
·Non-chlorine compounds: PCBS, PCPS, polybrominated biphenyl PBBS, polybrominated biphenyl oxide PBBOs,
