They may be represented mainly by polyethylene, polypropylene, polyvinyl chloride, and polystyrene. Specialty resins are plastics whose Attributes are tailored to particular apps and that happen to be manufactured at reduced volume and better Charge. Amongst this group will be the so-named engineering plastics, or engineering resins, which happen to be plastics that may compete with die-cast metals in plumbing, hardware, and automotive apps.
As talked about earlier mentioned, polymers which can be classified as plastics may be divided into two major groups: thermoplastics and thermosets. Thermoplastics like polyethylene and polystyrene are effective at staying molded and remolded frequently.
