Thermoplastics repeated linear one monomers Thermosets stretched cannot net Elastomers high melted elastic recycled cooling

Plastics can be classified into three groups : thermoplastics , thermosets and elastomers .
1 . are the most abundant . They are made up of chains of that form a kind of knot . When we heat them , they deform at low temperatures and can even be and take another form . The heating and process can be several times , so they can be .
2 . are made up of strongly linked molecular chains which form a kind of . Therefore , they resist temperatures and they can only be shaped time . As a consequence , they are very difficult to recycle .
3 . are materials which can be and compressed . So they are very materials . They be recycled .
