Important plastics characteristics are their technical properties, such as mouldability, hardness, elasticity, breaking strength, temperature and heat resistance and chemical resistance.
Resistance, which can be varied within wide limits by selecting the macromolecules, manufacturing processes and usually by adding additives. Plastics are divided into three major groups in accordance with their physical properties: Thermoplastics, duroplastics and elastomers.
Plastics are further processed into moulded parts, semi-finished products, fibres or films. They are used as packaging materials, textile fibres, thermal insulation, pipes, floor coverings, components of paints, adhesives and cosmetics, in electrical engineering as material for insulation, circuit boards, housings, in vehicle construction as material for tyres, upholstery, dashboards, petrol tanks and much more.
