    - Plastics are most commonly classified into two categories.

    1. Thermoplastic
    2. Thermosetting

    - The plastics which soften when heat is applied with or without pressure, but requires cooling to set them to shape are called as thermoplastic materials.

    - In the case, when thermoplastics are not heated above their decomposition temperature, then these can be heated and cooled any number of times.

    - Thermoplastic materials are easy for moulding and shaping.
