Definition - What does Thermoplastic mean?
A thermoplastic is a type of plastic made up of polymer resins that becomes a soft material when it is heated and becomes hard when it is cooled. These materials are easily recycled and do not show any chemical property changes when they are heated or cooled multiple times. When thermoplastics are heated their physical property changes and they become a homogenized liquid and can be reshaped and resized.
Corrosionpedia explains Thermoplastic
In harsh acidic environments such as in cities, 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 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 ¼ inch to 16 inches and are often used for water pipes in residential and commercial buildings.
Common materials used to manufacture these pipes are PVC or CPVC. Additional materials include polypropylene, PVDF, ABS, nylon and polyethylene. Polyethylene gas tanks are used to transport natural gas for residential and commercial purposes.
