ELECTRICAL INSULATION: Suitable for electrical insulation, wire bundling, color coding, mechanical protection, wire or cable joints, and daily maintenance. QUICKLY SHRINKS WHEN HEATED: The heat shrinkable tube quickly conforms to wires and components when heated, providing a tight fit and enhanced protection. 2:1 SHRINKAGE RATIO: Features a 2:1 shrink ratio, tightly sealing around objects for reliable coverage and durability. RESISTANT PROPERTIES: Offers excellent resistance to abrasion, aging, corrosion, and moisture; provides environmental protection and electrical insulation. WIDELY USED FOR INSULATION PROTECTION: Commonly used for insulating and protecting wire harnesses, solder joints, inductors, and connections against rust and environmental damage.
