Co-extruded from flexible polyolefin and hot-melt wire harness adhesive and used to protect the insulation of wires, cables, wiring harnesses and connectors that need to be sealed, waterproof and moisture-proof.
Co-extruded from flexible polyolefin and hot-melt wire harness adhesive and used to protect the insulation of wires, cables, wiring harnesses and connectors that need to be sealed, waterproof and moisture-proof.
HESA-Xinneng special waterproof heat shrink tube for automotive wiring harness can be well applied in many industries, such as electronics and electrical appliances, automobile, communication, etc.
Heat shrink tubing with HESA adhesive is also widely used in automotive wiring harnesses, household wiring harnesses, wire and cable branches, metal pipes and other places where insulation protection is needed.
1.Shrinkage ratio 4:1
2.Superior hot melt adhesive and high shrinkage rate ensure superior sealing
3.Sealing and insulation protection for electronic connection applications.
4.Easy to repair damaged insulation without removing the connector.
