Product Description
Engineered for the most demanding electrical and environmental conditions, this premium dual-wall heat shrinkable tubing delivers unparalleled protection for critical wiring systems. The outer jacket is constructed from a highly resilient, cross-linked, flame-retardant polyolefin that offers exceptional defense against mechanical abrasion, chemical exposure, and physical impact. Co-extruded with this outer layer is a thick, environmentally friendly hot-melt adhesive inner lining. During the heating process, as the polyolefin jacket contracts to its final dimensions, the adhesive lining melts and flows dynamically. This molten glue completely fills all internal micro-voids, conforming perfectly to the underlying wires, connectors, or splices. Once cooled, the system solidifies into a permanent, rigid yet flexible barrier that completely locks out moisture, corrosive fluids, and atmospheric contaminants. The tactile feel of the tubing prior to installation is smooth and pliable, allowing for easy routing in tight spaces. After shrinkage, the surface becomes robust and firm, providing excellent strain relief that prevents wire fatigue at connection points. Featuring an impressive high shrink ratio—typically 3:1 or 4:1—this tubing easily accommodates highly irregular shapes, bulky connectors, and significant transitions in wire diameters within a single continuous run. It operates flawlessly across a broad temperature range, ensuring the protective seal remains uncompromised whether installed in freezing outdoor enclosures or within the intense thermal environment of an industrial engine compartment.
◆ Function & Performance Capabilities:
1. wire coat and insulation: Delivers a durable, high-dielectric barrier over bare conductors and damaged sheathing, effectively preventing electrical shorts, arc tracking, and ensuring safe, uninterrupted operation under high voltage loads.
2. make the joint of terminal block and wire insulated: Provides essential mechanical reinforcement and electrical isolation at the critical, vulnerable junctions between rigid terminal blocks and flexible wire ends, acting as a robust strain relief mechanism.
3. divide the colors: Facilitates clear visual identification and phase division of complex wire harnesses and circuitry through a standardized, fade-resistant color system, dramatically simplifying long-term maintenance, routing, and troubleshooting.
4. water-proof: The internal hot-melt adhesive creates a true industrial-grade, impermeable environmental seal against water ingress, high humidity, lubricating oils, and corrosive industrial fluids, preventing oxidation of the conductive elements.
5. protection and insulation of insistors and electrical capacitors: Securely encapsulates sensitive inline electronic components, shielding them from mechanical impact, dust accumulation, and destructive vibration while maintaining optimal thermal stability.
◆ Standard color : black, white, red, blue, yellow, green, brown, grey, orange and purple.
The following technical data sheet outlines the precise dimensional parameters of our heat shrinkable tubing, documenting both the initial supplied state (As Supplied) and the fully recovered state (After Shrinking). Strict manufacturing tolerances are maintained throughout the extrusion process to ensure consistent wall thickness and internal diameters, which are absolutely critical for achieving a uniform, reliable seal around complex geometries. The comprehensive range of sizes, spanning from an internal diameter of 1.0mm (DRS-1) up to a massive 150.0mm (DRS-150), accommodates everything from delicate micro-electronics to heavy-duty industrial power cables. Furthermore, the packaging is strategically optimized by roll length (ranging from 25m to 200m per roll) to support continuous production lines, minimize material waste, and streamline inventory management during large-scale assembly operations.

This adhesive-lined, dual-wall tubing is specifically engineered to perform reliably in harsh environments where standard single-wall tubing cannot provide adequate protection. In the automotive industry, it is extensively deployed to protect complex wire harnesses from exposure to engine fluids, road salt, and constant mechanical vibration. For marine and offshore applications, the superior waterproofing capabilities prevent aggressive saltwater corrosion on exposed electrical splices and navigation wiring. Industrial control systems rely heavily on this tubing to maintain pristine signal integrity in humid, dusty, or chemically aggressive manufacturing facilities. Additionally, it provides essential strain relief and electrical insulation for telecommunication base stations, renewable energy installations, and everyday home appliances, ensuring long-term operational safety across a multitude of diverse sectors.
Beyond providing basic electrical insulation, the dual-wall construction delivers exceptional physical resilience for demanding applications. The cross-linked polyolefin outer jacket actively resists scuffing, tearing, and splitting, even when cables are aggressively pulled through tight, abrasive conduits or subjected to constant friction in dynamic assemblies. Electrically, the material boasts an exceptionally high dielectric strength, effectively preventing arc tracking and dangerous current leakage over the lifespan of the installation. Importantly, the inner adhesive layer remains highly flexible even after cooling; this means the sealed joint can bend and flex with the cable without cracking, delaminating, or compromising the critical moisture barrier.
Meeting the rigorous demands of modern international engineering projects requires strict adherence to global quality and safety standards. This heat shrinkable tubing is fully compliant with UL safety regulations, confirming its dependable flame-retardant properties and long-term electrical reliability under stress. Furthermore, it strictly adheres to RoHS and REACH environmental directives, guaranteeing that all materials utilized in its construction are entirely free from hazardous substances and heavy metals. This unwavering commitment to environmental responsibility and operational safety ensures seamless integration into compliant supply chains and end-products destined for strictly regulated global markets.
Understanding that every engineering project and manufacturing process has unique requirements, a comprehensive suite of customization and supply chain services is readily available. While the tubing comes in ten standard colors, it can be precisely color-matched to specific corporate branding or complex technical guidelines upon request. Advanced surface printing capabilities allow for the clear, permanent marking of part numbers, company logos, or technical specifications directly onto the polyolefin jacket—markings that remain fully legible even after the shrinking process is complete. For manufacturing efficiency and OEM/ODM integration, the tubing can be supplied in custom-cut lengths rather than standard spools, arriving ready for immediate assembly line integration. Flexible, scalable packaging solutions are designed to accommodate varying production volumes, ensuring that inventory aligns perfectly with your operational demands and procurement schedules.
