Heat-shrink tubing is ordinarily made of a polyolefin, which shrinks radially (but not longitudinally) when heated, to between one-half and one-sixth of its diameter. Heat-shrink tubing is manufactured in a multitude of varieties and chemical makeups with the exact composition of each type being dependent on the intended application. [1]
The mainly used amorphous thermoplastic polyamides combine a favourable viscosity spectrum with a wide application temperature range from 50 to 150 °C or 122 to 302 °F. The material is heated until liquid (typically at 180 to 240 °C or 356 to 464 °F) and then injected at very low pressure, typically 3.5 to 14 bars (51 to 203 psi) into a ...
Heat shrink tape is applied to a composite part prior to the heating, or curing cycle. When heated, the tape will shrink in the linear (machine direction). Heat shrink tape works best on parts that are cylindrical or semi-circular in cross section, as this allows the tape to exert even compaction forces on the part surface.

Primers for heat-shrinkable sleeves work in the same manner as an FBE primer does when it is specified on 3-layer polyolefin pipeline coatings and is typically applied between 150 μm and 300 μm thick. Usually, the primer of heat shrinkable sleeve is two components non-solvent Epoxy, one is primer base and the other is curing agent.
Tesla took heat in 2024 for sending out an insensitive email about layoffs that reportedly started with "Dear Employee." GM did not respond to questions about how it handled the Nov. 15 job cuts.
Instead of being able to calmly focus on her chemotherapy treatment, Arete Tsoukalas had to spend hours on the phone arguing with her insurer while receiving infusions in the hospital.
Key COC enhancements can include thermoformability, shrink, deadfold, easy tear, enhanced stiffness, heat resistance and higher moisture barrier. Common applications include shrink films and labels, twist films, protective or bubble packaging, and forming films. Another noted application which often relies on a high percentage of COC in the end ...
