SEALED & PROTECTED WITH HEAT SHRINK TUBING TE Connectivity's Heat Shrink Tubing Offers a Superior Alternative to Tape, Glues and Glass PERFORMANCE MATERIALS / SEALED & PROTECTED WITH HEAT SHRINK TUBING 3 The Difference Between Single Wall & Dual Wall Heat Shrink Tubing Single Wall Heat Shrink Tubing for Quick Insulation and Protection Single wall heat shrink tubing provides superior insulation, strain relief, and protection against mechanical damage and abrasion versus taping and molding in place. This high-performance alternative has reliably consistent dimensions and physical properties, with shrink ratios of 2:1 to 4:1. When heated, the single-wall tubing shrinks to conform to the size and shape of the underlying material, making installation fast and easy. Single-wall tubing offers optimum flexibility and space savings along with mechanical protection and chemical resistance. Across appliance designs, single-wall heat shrink tubing is also useful for noise reduction, identification and organization—for example, for bundling wires or assembling cable harnesses. TE products also come in a wide range of sizes, colors, and materials, and many products are offered in flame retardant versions. Most of our products are UL recognized/CSA certified and some meet SAE 23053, MIL-PRF-46846 and VG95343 standards. Dual Wall Heat Shrink Tubing: Ideal for Sealing and Protecting Against Fluids and Corrosion Nearly anywhere corrosion protection and sealing are required, dual-wall heat shrink tubing should be considered as a top choice over taping, molding and potting. Dual-wall tubing uses engineered adhesives to protect against moisture, chemicals, and corrosive conditions and provide electrical insulation and mechanical protection. TE's Raychem dual-wall tubing products have a cross-linked outer jacket and an inner layer of adhesive or encapsulant. The highly engineered adhesives can bond with many different types of materials. During installation, the adhesive lining melts and flows, creating a moisture-resistant protective barrier that seals and protects against dust and fluid ingress. This provides more consistent results for the user during assembly due to the controlled amounts of adhesive within, and tubing can be applied quicker and easier than potting, for example. TE's dual-wall heat shrink tubing products offer shrink ratios ranging from 2:1 to 6:1, and are resistant to flame, heat, chemicals and mechanical damage. Depending on the intended use, different products are certified in compliance with SAE 23053 standards, UL and CSA, and RoHS. Select tubing products are also type-approved by the American Bureau of Shipping (ABS) and Lloyd's Registry of Shipping. • Fluid resistance • Up to 600 V electrical insulation rating • Maximum temperature rating of 150°C to 200°C • Mechanical interference protection When compared to using tape, glues or glass, tubing with cross-linking technology offers outstanding benefits. It can operate at higher temperatures without melting. Its high mechanical strength means it is more resistant to impacts and abrasions. Cross-linked heat shrink tubing can also be used to bundle or collate different wires and small pipes for easy organization and identification. Other benefits include:
