3 Types of plastic - ansThermoplastics- can be reheated and reshaped as they have loose monomer chains, can be recycled and coloured pigments can be added to make it more aesthetically pleasing. Thermosets - undergo a chemical change so permanently rigid, cannot be reheated or reshaped as it forms rigid cross links, e.g. spoons. Elastomers - can be distorted under pressure but will return to their original shape. Properties of plastics - ans-Electrical and thermal insulators. -Good str...
