RS PRO Heat Shrink Tubing, Black 25 mm Sleeve Dia. x 3m Length 3:1 Ratio

From the trusted brand RS PRO, a range of heat shrinkable tubing commonly used in electrical applications. This heat-shrink tubing has an outer layer made of radiation cross-linked polyolefin and an inner layer coated with hot melt adhesive. Once heated, the outer protective layer is formed and the inner forms an adhesive layer that can protect against moisture and secure object firmly. Adhesive lined heat shrink offers excellent insulation and adhesion to rubber, PVC, PE, aluminium and can be used in various fields of repairing wires and moisture-proof requirements.

Heat shrink tubing is a type of extruded plastic tubing that can be cut to size and fitted over a wire or cable joint to protect and insulate the connection. When heated is applied the tubing shrinks permanently providing a protective seal. The amount it shrinks depends on its shrink ratio. When you buy the tubing, it is in its expanded state, this expanded tubing has a memory so when it is heated it returns to its original state. Larger shrink ratios are required to cover materials with a greater size variation.
