Polyesters are versatile plastics which can be used to make a whole host of products, from textile fibres and PET drinks bottles to CDs and food packaging, etc.
Polyolefins are the most important group of plastics. The main representatives from this group are polyethylene and polypropylene.
Polyurethanes are synthetic resins or plastics. Depending on how they are produced, they may be soft and elastic or brittle and hard. The elastomers, in particular, are extremely tear-resistant.
