High Temperature Heat Shrinkable Tube
PTFE heat shrinkable tubing is made of PTFE with high temperature performance, chemical resistance, high insulation and excellent mechanical properties. Designed to provide insulation and mechanical protection in severe chemical and thermal environments. Widely used in electronic, aerospace, military and communication fields. Used to cover hydraulic hose and couplings to prevent contamination and corrosion. The high mechanical strength and extremely low coefficient of friction make it good for reducing damage to bearing shafts and similar applications.
