Heat shrink
makerHeat shrink is a protective plastic sheath that contracts when exposed to heat, used for insulating wires and cables.
expanded
Heat shrink tubing is a versatile insulating material that reduces in diameter when exposed to heat, typically using a heat gun, to fit tightly around wires and cables. It is crucial in protecting against environmental factors such as abrasion and moisture, ensuring electrical safety and cable management, particularly in electronic and electrical applications.
examples
A 3:1 ratio polyolefin heat shrink tubing with an initial diameter of 12 mm (0.47 in) and a recovered diameter of 4 mm (0.16 in).
Commonly used in automotive wiring harness repairs to provide water-resistant and abrasion-resistant insulation around terminals and connectors.
Flexible, adhesive-lined heat shrink tubing with a wall thickness of 1.2 mm (0.047 in) after shrinking.
Applied in electronics to protect soldered joints in PCBs against moisture ingress, ensuring long-term durability and performance.
