TE Connectivity Heat Shrink Tubing, Black 25.4mm Sleeve Dia. x 300mm Length 3:1 Ratio, SCL Series / 397865

AMS-DTL 23053/ 4 class 1. Raychem SCL™. SCL tubing is a semi-rigid heat shrinkable tubing with a meltable inner wall, designed to provide one-step moisture proof encapsulation of a wide variety of electrical parts including wire splices, breakouts, and electronic components. Manufactured from radiation cross linked polyolefins, the outer wall shrinks when heated to above 135°C, while the inner wall (which melts at 100°C) flows into the crevices and interstices by the shrinking action of the outer tubing. When cooled the entire mass becomes a rigid, tough, homogenous covering with a controlled wall thickness. SCL® shrinks to between 17% and 40% of its supplied diameter according to size, and therefore few sizes are required to cover a range of irregular shapes with widely varying dimensions. Unaffected by most solvents and chemicals and non-corrosive in contact with electrical joints, SCL also has high dielectric strength (240-410 kV/cm dependent on wall thickness).
