Eco-Friendly V0 Flame Retardant Dual-Wall TubeReturn
The eco-friendly V0 flame retardant dual-wall tubing consists of two layers: an outer layer of highly flame-retardant polyolefin insulation material and an inner layer of hot melt adhesive. The inner adhesive layer provides mechanical strain relief and excellent sealing performance.
Its primary functions include waterproof sealing, corrosion prevention, gas leakage prevention, multi-strand wire bundling, and insulation. It is widely used in various wiring harnesses, marine cables, and metal pipes requiring waterproof sealing, moisture resistance, corrosion protection, insulation, and bundling applications.
