A material can be moulded when it can be placed in a cavity and given a definite form. For plastics this requires the use of heat. Most plastics are superb at being moulded.
A material is ductile when it can be easily stretched without breaking. For plastics this requires the use of heat in most cases.
Thermo plastics can be shaped when heated. If allowed to cool they will remain in the new form. This process is repeatable.
All of the everyday plastics are excellent electrical and thermal insulators. This means that it is very difficult for energy in the form of heat or electricity to pass through them.
A fantastic property of most plastics is that they are self - coloured and require no extra finish applied for appearance or protection
