Detailed Description for Heat Shrinkable PVC Sleeves


·         Composite structure of the reinforced Rayfort sleeve offers an excellent resistance to mechanical abuse during and after the installation.

·         Integrated moisture barrier completely reconstitutes the cable sheath over the total splice area.

·         Hot-melt adhesive forms a watertight seal to the cable sheath.

·         A metal canister shapes and mechanically protects the splice bundle.

·         Up to 3 cables at each end can be accommodated using three finger clips with hot-melt adhesive.

·         Installation indicators: heat sensitive paint and adhesive flow, white line

·         Extended size range can accommodate splices up to 3600 pair with any connector type.

·         Unlimited shelf life.

·         Resistant to UV-radiation

·         High electrical insulation

·         Superior mechanical property



·         Heat shrink tube is a mechanically expanded extruded plastic tube ordinarily made of nylon or polyolefin, which shrinks when heated in an effort to return to the relaxed diameter it originally had when extruded.

·         Heat shrink tube is used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical engineering. It can also be used to repair the insulation on wires or to bundle them together, to protect wires or small parts from minor abrasion, and to create cable entry seals, offering environmental sealing protection.



·         Wire splices and terminations

·         Wire harnesses

·         Mechanical protection and fire-resistant covering

·         Insulation and strain relief of terminals and connections


Uses of Heat Shrink Tubing:

·         Protective Sealant: Heat shrink tubing is often used to seal water and dust out of cables and cable splices. It is ideal for protecting home theater and personal computing connections from moisture.

·         Insulation from Heat and Chemicals: Extreme heat and exposure to chemicals can damage cables. Flame retardant heat shrink tubing can be used to insulate the wires of a car or boat's electrical system.

·         Easy Identification: Cables tend to get tangled, which makes their routing hard to identify. Because heat shrink tubing comes in a variety of colors its ideal for color coding messy groups of network cables. Using heat shrink tubing for labeling is a smart alternative to labeling with adhesive tape due to the protective nature of the tubing itself.

·         Strain Relief: Cables from your personal computer or home theater are often strained due to insufficient length or tight quarters. Fitting these cables with heat shrink tubing can relieve that strain, prolonging their life span in the process

·         Soldering: Instead of soldering, heat shrink tubing lined with conductive polymer film can be used to join two wire splices. The inner coating of polymer film creates an electrical connection, allowing you to join two wires and protect them simultaneously.
