Application areas:
Applications requiring sealing include wire connections in electronic devices, automotive wiring harnesses, household wiring harnesses, wire and cable branches, metal pipelines, wire and cable repairs, and submersible pump wiring.
Product Description
SBRS-(3X)GLW(3:1) Soft Thick Adhesive Low-Temperature Shrink Double-Wall Tube is composed of two layers: a soft, flame-retardant polyolefin material and hot melt adhesive. The outer polyolefin layer is soft, flame-retardant, and shrinks at low temperatures, while the inner hot melt adhesive layer buffers mechanical strain and provides strong sealing. Its main functions are sealing and waterproofing, corrosion prevention, leak prevention, and insulation protection. It is primarily used in applications requiring sealing, such as wire connections in electronic equipment, automotive wiring harnesses, household wiring harnesses, wire and cable branches, metal pipelines, wire and cable repair, and submersible pump wiring.
Features:
Heat shrink ratio: 3:1
Initial shrinkage temperature: ≥ + 60 ℃
Complete shrinkage temperature: ≥ +105 ℃
Operating temperature: -45 ℃ ~ +125 ℃
The outer layer is flame-retardant, UV-resistant, and very soft.
Environmental Standards: RoHS
Standard color: Black (other colors can be customized)
