Description
High-Temp Heat Shrink Sleeves are heat-shrink tubing made from a specialized polymer material.
When heated (typically 125°C–350°C), the tubing shrinks proportionally, tightly wrapping around cables, solder joints, terminals, or fittings.
Their primary functions are insulation, protection, and high-temperature and chemical resistance.
Structure: Silicone rubber + inner wall with hot melt adhesive, which is sealed, waterproof and moisture-proof when shrinking.
