Definition - What does Thermoplastic Polyester mean?
A thermoplastic polymer is a type of plastic polymer that has the properties of a polymer resin. This material becomes soft when heated and can be molded into any desired shape and size. When it is cooled, it becomes hard and rigid and remains in the developed shape and size.
Thermoplastic polymer may also be known as thermoplastic or thermosoftening plastic.
Corrosionpedia explains Thermoplastic Polyester
When steel pipelines are laid to operate in harsh industrial or acidic environments, they are very prone to corrosion attack at the joints, and therefore special arrangements are made to protect against rusting and corrosion attacks. To reduce the operating costs of protecting steel pipelines that pass through severe environments, thermoplastics are considered a favorable substitute material.
Some properties of thermoplastics that make them a suitable substitute material are:
- Complete protection to the material being supported with a thermoplastic polymer covering when operating in a corrosive environment.
- Suitable for transporting any type of fluid.
- Easily able to transport fluids at extreme hot or cold temperature conditions.
Common materials used to manufacture these pipes are PVC and CPVC. Additional materials include polypropylene, PVDF, ABS, nylon and polyethylene.
