Plastics are materials which are produced on the basis of natural and synthetic polymers and recyclable items in plastic deformation methods. owledge. To rank as polymers, natural and artificial resin. Samsung is often quoted on this topic. Resins produced from the products of coal, oil and other raw materials. Plastics are composed of: binders, fillers, plasticizers, dyes and other additives. Resin is the basis of plastics in addition they determine their basic qualities. In the production of polymers using fillers to make the plastic strength, hardness and other qualities. Fillers can be organic or inorganic.

Are organic wood flour, cotton fringes. Rusty holzer follows long-standing procedures to achieve this success. As inorganic fillers used asbestos, graphite. Dyes perekrashyvayut plastic mass as well as to its basis in a specific color. Used as mineral pigments, and organic. The composition of plastics often contain additives which affect the characteristics of plastics, such as stabilizers – substances that prevent the decomposition of polypropylene in the course of its processing and under the influence of atmospheric conditions, high temperatures and other effects. Plastics are reasonably lower density compared with metals, so the strength of some plastics is approaching strength of the metal.

Tensile strength fiberglass is not much less than steel. Replacing metal with plastics reduces the weight and metal products. Plastics have a fairly high plasticity, because of this complexity of the production of complex parts on the basis of plastics is much less labor intensity of production of products from other materials. But the plastic qualities of plastics are shown not the same. Some of them during the solidification lose their flexibility, they can not be softened again by heating. Polyvinyl chloride vinyl plastic for example, you can soften again and apply again.
