4:1 Dual Wall Heat Shrink Tubing
Dual-wall with adhesive & 4:1 shrinkage for excellent sealing and compatibility! Featuring an eco-friendly, irradiated cross-linked polyolefin dual-wall structure, the outer layer provides insulation and flame retardancy, while the inner layer is made of high-temperature hot-melt adhesive. With a strict 4:1 shrink ratio, it starts shrinking at 80℃ and fully shrinks with the adhesive melting at 120℃. After heating, it fits tightly around cables and connectors without gaps or looseness. Dielectric strength reaches 1KV. It operates stably under extreme conditions from -55℃ to 125℃, is flame-retardant, corrosion-resistant, waterproof and moisture-proof, effectively isolating moisture, dust and chemical corrosion. Supplied in full rolls with sufficient length to meet batch construction needs, and especially suitable for connectors with large size differences. All-scenario sealing protection, reliable even in complex working conditions! For automotive wiring, ship engine rooms and other humid & vibrating environments, it delivers stable performance with strong sealing and anti-vibration properties. For outdoor wiring in photovoltaic power stations and underwater operation of water pumps, it is waterproof, moisture-proof and corrosion-resistant, guarding against harsh weather and medium erosion. For special-shaped terminals of industrial equipment and connection between thick and thin cables in outdoor engineering, the 4:1 shrink ratio enables precise wrapping, combining insulation and mechanical protection, preventing electric leakage and connector aging. It is a highly reliable accessory for industrial construction and equipment maintenance.
