Thermoplastics

Thermoplastics are a family of plastics that can be molten when heated and hard when cooled. When frozen, however, a thermoplastic becomes glass-like and subject to fracture. These characteristics, which lend the material its name, are reversible. That is, it can be reheated, reshaped, and frozen repeatedly. This quality also makes mechanically recyclable.

There are dozens of kinds of thermoplastics, with each type varying in crystalline organization and density. Some types that are commonly produced today are polypropylene, polyethylene, polyvinylchloride, polystyrene, polyethylenetheraphthalate and polycarbonate.

  • History


    Celluloid, which is considered the first thermoplastic, made its appearance in the mid-1800s and reigned in the industry for approximately 100 years.

    During its peak production, it was used as a substitute for ivory. Today, it is used to make guitar picks.

    Since that time, different thermoplastic types made their entry (see: types of plastics).
