ProFIT Heat Shrinkable Tubing

The ICO RALLY brand of heat shrinkable products is made from thermoplastic material such as polyolefins, fluoropolymers, PVC, neoprene, and silicone elastomers. The tubing shrinks in diameter when heated to provide insulation, abrasion protection, strain relief, identification, and aesthetic appeal. Available in a variety of wall thicknesses, colors, and sizes, ICO RALLY is sure to have the exact tubing required to meet your specific application. Many of these products meet the SAE-AMS-DTL-23053 military standard for heat shrinkable tubing.

Melt Wall vs Adhesive-Lined Polyolefin

Melt Wall / Poly Melt Wall Polyolefin Tubing is a semi-rigid, heat shrinkable tubing that is coextruded and selectively cross-linked to provide a tough protective outer shrinkable jacket with a meltable inner wall.

With the application of heat in access of 135C, the inner wall melts and is forced by the outer wall to flow in and around all underlying surfaces and small voids. When cool, the tubing becomes one solid mass excellent for encapsulating delicate components from moisture and the attack of chemicals and solvents. Melt Wall Polyolefin Tubing is recommended for a wide variety of electronic, electrical and mechanical applications... wherever a highly reliable, one-step approach to jacketing, encapsulation and environmental sealing is required.

Adhesive-Lined Heat Shrink Tubing is a flexible Heat Shrink Poly W/Adhpolyolefin lined with a thin layer of special thermoplastic adhesive for excellent moisture protection and strain relief. This tubing offers convenient protection of electrical components, wire splices or bundling of wires. Automotive, truck and marine wiring splices and connections are quickly and easily protected from harsh environments. With the application of heat, adhesive-lined heat shrink tubing shrinks to a tight fit, forcing the adhesive lining to flow and cover the substrate. When cooled the adhesive forms a permanent, flexible and waterproof barrier.
