Flame Retardant Dual Wall Heat Shrink Tubing (Item HAFR140, Heavy Wall Adhesive Lined Tubing, Black, 3:1 Shrink Ratio)
ApplicationThe flame retardant dual wall heat shrink tubing consists of two layers which is retardant EVA and hot-melt adhesive. The outer one is EVA and the inner one is hot-melt adhesive. Flame retardant dual wall heat shrink tubing has excellent advantages in insulation, sealing, waterproof, mechanical protection, moisture prevention and impact resistance and can also resist ultraviolet rays.
