Nowadays we owe many beneficial solutions, from the environmental and economic point of view, to plastics. Many branches of industry, especially those that use advanced technologies related to medicine, science and information technology, are rapidly expanding due to the availability of new polymer materials, their use in modern technological solutions as well as in modern design. Moreover, plastics often have the advantage over conventional materials and many new developments would not be possible without them.
The primary advantages are:
The ability to adapt a variety of properties to suit the requirements. Simply select the specific grade of plastic which meets your expectations in terms of hardness, stiffness, impact resistance, insulating properties, colour and weight and the environment in which the finished product will operate.
Ease of processing. Plastics can be shaped and moulded with many methods, such as extrusion, injection moulding, moulding, pressing, thermal moulding, blow moulding, and cutting.
Cost savings. The use of plastics is more cost effective than that of other materials. One of the advantages is their lightness, which means that both the production and the delivery costs are lower due to the lower consumption of raw materials and energy during production, simpler transfer/transport, less fuel for transport, less pollution during transport, and less waste.
Environmental benefits - recycling and suitability for reuse. A significant amount of plastic waste is suitable for re-use after re-granulation; for example, in the production of garbage bags, compost bins, road signs, boxes for drinks and clothing.
Exceptional strength. Plastics are resistant to impact and flexural strength. This means that having the choice between plastic and metal in a situation where low weight and strength are important, plastic is often selected.
Low friction. Plastics have a low coefficient of friction and are therefore ideal material for stable, moving parts such as gears, gear wheels, conveyor belts, and bearings.
Non-conductivity. Plastics are excellent for insulating electrical cables, holders/sockets, switches, panels, electrical equipment, and conductor rails.
Plastics are basically maintenance free. They are resistant to water and weather factors, their surface does not degrade by the effects of sun, frost, and most chemicals, while dirt can be easily removed. Just think about the clothes we wear, the houses we live in or means of transport we use. At work or during our leisure time, we use ever more sophisticated computers, telecommunications and sports equipment. While shopping in a supermarket, undergoing major surgery or simply brushing our teeth - whatever we do, we are surrounded by commodities, products and parts made of plastics.
