Product Introduction
260℃ Teflon Heat Shrink Sleeve is made of polytetrafluoroethylene (PTFE TEFLON), which can be used for a long time at high temperature of 260℃. It has wear resistance, oil resistance, chemical resistance and high temperature resistance. has excellent fire retardant properties, physical and chemical properties and an extremely low coefficient of friction.
It is widely used for insulation protection of high temperature wire harnesses, welding joints, pressure relief, identification of covered components, and in automotive, military, aviation, aerospace and other fields.
Functions:
Shrinkage ratio: 1.7:1, 4:1.
High fire resistance, excellent electrochemical properties.
Very low coefficient of friction
Complies with ROHS environmental protection requirements
operating indicators
Final shrinkage temperature: 350℃.
Working temperature: -65℃～260℃.
