`
`Physical properties of some common plastic materials are indicated below.
`Thermoplastics
`
`Thermoplastics can be softened as often as they are reheated and are not so rigid as thermosetting
`plastics but tend to be rougher.

`
`Termosets (Thermosetting Plastics)
`
`Thermosetting plastics undergo a chemical change during moulding an can never again be softened
`by reheating. The chemical change in the moulding process is triggered by temperature and pressure
`and is called curing.
`
`Thermosetting plastics are harder and more brittle than thermoplastic materials.
