Application areas:
Specifically designed for use in metal pipe fittings, welded joints of threaded steel bars, or other connections requiring sealing and protection.
Product Description
Product Introduction:
The inner wall of this construction welding protective tape is made of adhesive heat-shrink tubing, while the outer radiation-crosslinked polyolefin sheath provides effective insulation protection. The inner adhesive layer provides excellent waterproof and moisture-proof protection for welding. It is specifically designed for metal pipe fittings, threaded steel welds, or other connections requiring sealing protection.
Features:
Initial shrinkage temperature: ≥ +70 ℃
Complete shrinkage temperature: ≥ +125 ℃
Operating temperature: -45 ℃ ~ +110 ℃
High shrinkage rate, sealed and waterproof, moisture-proof, flame-retardant outer layer.
Environmental Standards: RoHS
Standard color: Black (other colors can be customized)
