Heavy wall heat shrinkable insulation tube

 

Features/Applications

HR3 is semi-rigid heavy wall tubing without hot melting Adhesive. With properties of excellent insulating and resistant to mechanical impact it can protect electrical cable splices, terminations and joints where electrical Insulation are required. 3:1 shrink ratio allows it easily fit to irregular shape and large connectors.

 

   !. Resistant to UV

   2. High electrical insulation

   3. Superior mechanical protection

   4. Minimum fully recovery temperature: 120 °C

Standard color: Black, Red
