2. Heat-shrink tubing - Wikipedia

   en.wikipedia.org/wiki/Heat-shrink_tubing

   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 ]

3. Shrink wrap - Wikipedia

   en.wikipedia.org/wiki/Shrink_wrap

   Shrink wrap, also shrink film, is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering. [1] [2] [3] Heat can be applied with a handheld heat gun (electric or gas), or the product and film can pass through a heat tunnel on a conveyor.

5. Heat-shrinkable sleeve - Wikipedia

   en.wikipedia.org/wiki/Heat-shrinkable_sleeve

   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.

6. Polyolefin - Wikipedia

   en.wikipedia.org/wiki/Polyolefin

   A polyolefin is a type of polymer with the general formula (CH 2 CHR) n where R is an alkyl group. They are usually derived from a small set of simple olefins ( alkenes ). Dominant in a commercial sense are polyethylene and polypropylene .

7. Hot-melt adhesive - Wikipedia

   en.wikipedia.org/wiki/Hot-melt_adhesive

   Amorphous polyolefin (APO/APAO) polymers are compatible with many solvents, tackifiers, waxes, and polymers; they find wide use in many adhesive applications. APO hot melts have good fuel and acid resistance, moderate heat resistance, are tacky, soft and flexible, have good adhesion and longer open times than crystalline polyolefins.
