Definition - What does Thermoplastic mean?

Thermoplastic is a type of plastic made up of polymer resin that becomes a soft material when heated and becomes hard when cooled. This material is easily recycled and does not show any chemical property change when it is heated or cooled multiple times. When thermoplastics are heated their physical property changes and they become a homogenized liquid that can be reshaped and resized.

Petropedia explains Thermoplastic

In harsh acidic environments, steel piping systems are often susceptible to rust or corrosion at the joints and therefore need special arrangements for corrosion protection. To minimize the costs associated with protecting steel pipelines used for transporting hydrocarbons that pass through severe environments, thermoplastics are considered a favorable substitute material. Some of the properties of thermoplastics that make them a suitable substitute material are:

  • They handle corrosive materials and corrosive environments well.
  • They are able to carry materials of extreme temperatures (either hot or cold), therefore they are good for just about every type of fluid transport application.

Thermoplastic pipes usually have a small diameter, ranging from ΒΌ inch to 16 inches and are often used for transporting various fluids in the industrial as well as residential purposes.

Common materials used to manufacture these pipes are PVC or CPVC. Additional materials include polypropylene, PVDF, ABS, nylon and polyethylene.
