Plastic materials, in the general common term, are considered the artificial materials with a macromolecular structure that under certain conditions of temperature and pressure suffer permanent variations of form. They obtain malleability under the action of heat.
The beneficial characteristics of plastics compared to metal and not metal materials are the great ease of processing; economy; acoustic, thermal, electrical, mechanical insulation and corrosion resistance. Many plastic materials as nylon, teflon, plexiglass etc. are good for industrial production processes with machine tools quite similar to metallic materials.
Over the years many companies have obtained a succesful development in thermoplastic field, proposing a vaste range of products ad the well known products for safety protections.
