The difference between plastics and elastomers is actually quite simple. Plastics are made from oil and elastomers are made from synthetic material.
There isn't too much of a difference between elastomers and plastics. The only real difference between them is how far you can stretch them. Other than that they are really similar.
thermosetting plastic becomes hard when heated and deteriorates by excessive cross linking and thermoplastic becomes soft and can be moulded into any shape.
because of the difference in physical characteristics of thermoplastics and metals, there are corresponding differences between welding techniques for metals and thermo-plastics. in the welding of metal, welding rod and parent material become molten and fuse into the required bond to form welded joints. this is not in thermo plastics, because they are poor heat conductors , they are difficult to heat uniformly .. so diifferent methods are used to weld plastics...
The terms are used to categorise cable insulation according to its properties, such as its operating temperature, rather than the ingredients from which it is are made.These terms are now used by the IEE Wiring Regulations to describe insulation formerly described, for example, as 'pvc' (a 'thermoplastic' material) or rubber ( a 'thermosetting' material).
