2. Hot-melt adhesive - Wikipedia

   en.wikipedia.org/wiki/Hot-melt_adhesive

   The glue is sticky when hot, and solidifies in a few seconds to one minute. Hot-melt adhesives can also be applied by dipping or spraying, and are popular with hobbyists and crafters both for affixing and as an inexpensive alternative to resin casting. In industrial use, hot-melt adhesives provide several advantages over solvent-based adhesives.

3. Pressure-sensitive adhesive - Wikipedia

   en.wikipedia.org/wiki/Pressure-sensitive_adhesive

   Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt). In ...

4. Kraton (polymer) - Wikipedia

   en.wikipedia.org/wiki/Kraton_(polymer)

   Kraton polymers are always used in blends with various other ingredients like paraffinic oils, polyolefins, polystyrene, bitumen, tackifying resins, and fillers to provide a very large range of end-use products ranging from hot melt adhesives to impact-modified transparent polypropylene bins, from medical TPE compounds to modified bitumen ...

5. Heat-shrinkable sleeve - Wikipedia

   en.wikipedia.org/wiki/Heat-shrinkable_sleeve

   The choice of which adhesive to use is based on the pipeline design and operating conditions. As an example, for small diameter flow lines operating at ambient temperatures, a soft mastic-based adhesive may be chosen, while on large diameter pipelines operating at higher temperatures, a hard, semi-crystalline hot-melt adhesive is used. The ...

6. Polypropylene - Wikipedia

   en.wikipedia.org/wiki/Polypropylene

   PP objects can be joined with a two-part epoxy glue or using hot-glue guns. [59] PP can be melted using a speed tip welding technique. With speed welding, the plastic welder, similar to a soldering iron in appearance and wattage, is fitted with a feed tube for the plastic weld rod.

7. Polybutylene - Wikipedia

   en.wikipedia.org/wiki/Polybutylene

   It is also used synergistically as a blend element to modify the characteristics of other polyolefins like polypropylene and polyethylene. Because of its specific properties it is mainly used in pressure piping, flexible packaging, water heaters, compounding and hot melt adhesives.
