PE is one of the most widely used kinds of plastic. It was discovered by chance in 1933, when chemists Eric Fawcett and Reginald Gibson in Norwich, England, in the chemical industry, Imperial (Imperial Chemistry Industries), made a white, waxy material mother of plastic , which was eventually, because of it s possibilities, processed and improved. Production began in 1939. At that time polyethylene was used in military purposes, until the middle of the last century, when plastic entered into everyday life, along with global economic boom.

History of polypropylene began in 1954, when German and Italian chemists Karl Rehn and Giulio Natta, made the first polymerization. Commercialization began three years later. Polypropylene represents the most versatile polymer. It is used for the production of strength, flexible, light weight and resistance to heat products. Also polypropylene can be used for fibers and in the industrial and agricultural sector.

After polyethylene, PVC is the most important plastics. It was first discovered by Henri Victor Regnault in 1835, and after him one more time Eugen Baumann in 1872. Both times the polymer appeared as a white solid substance in the bottle vinyl chloride which are left in the sunlight. There were a few attempts of PVC commercialization, however, the material was difficult to process. Scientists Valo Semon s experiments have led to the creation of plasticization methods, by mixing PVC with various additives. The result was a material, which was easy to handle, and commercial use was wide. PVC is mostly produced with method called the suspension polymerization process. The polymerization is carried out at a low pressure of below 1 MPa, and temperature of 30 to 80 °C in the presence of an inorganic or organic peroxide activator.

Polycarbonates are a special group of thermoplastics. Processing, molding and thermoforming are easy, such plastics are plastics which are widely used in the modern manufacturing sector. It is one of the most important engineering plastics which is transparent, corrosion resistant, self-quenching when it does, time and temperature, and its dimensions are changed very little and all these have very good mechanical properties. Polycarbonate is suitable for both injection molding and extrusion.

POM is a widely used material in a wide variety of engineering applications in all industries. Easy to process, chemical resistance and high deformation under load; Resistant to abrasion, good dimensional stability and low moisture absorption, as well as an easily processable material.

Ethylene vinyl acetate (EVA) is the copolymerof etyhlene and vinyl acetate. It s an extremely elastic material that can be sintered to form a porous material similar to rubber, yet with excellent toughness. The porous elastomeric material is three times as low density polyethylene (LDPE), showing tensile elongation of %750 with a peak melting temperature of 250F (96 C). This flexible porous plastic material has good barrier properties, low temperature toughness, stress crack resistance, hot melt adhesive, and waterproof properties. Porous EVA has little or no odor and is competitive with rubber and vinyl products in many electrical applications.

Nylon (polyamide), is synthesized by Gariel and Maass in the lab in 1889, and commerializd by Dupont in 1930s. Dupont name the fiber Nylon. Commercially available the most popular nylons include nylon PA 6, nylon PA 66, nylon PA 11 and nylon PA 12. The numerical nomenclature for nylon is derived from the number of carbon atoms in the diamine and dibasic acid monomers used to manufacture it. The ratio of carbon atoms is what gives each nylon type its unique property characteristics.

PVC is mild and powerfull plastic. PVC is manufactured more softer and flexible with the help of plasticizers. In addition to that, Soft PVC can be found in different range of stiffness.

Crystalline form of calcite calcium carbonate in the hexagonal system. The density of calcitine is 2.75 g / cm3. The melting point is 1339 ° C under 1.025 atmospheres pressure. Calcite is the main element of the limestone. The pure crystal contains 56% calcium oxide (CaO), 44% carbon dioxide (CO2). In impure crystals, some of the calcium may have been replaced by Fe, Mg and Mn. Calcite is in the form of mineral veins in nature and is often formed with lead, zinc, silver and other ores. Calcite is a crystallized calcium carbonate whose chemical formula is CaCO3. It can be transparent, white, yellow, rustic green and bluish color. Strength is 3, specific weight is 2.71. Cold and dilute hydrochloric acid (salt spirit) decomposes with severe foaming. It is drawn with a knife. It dissolves in CO2 water to make Ca (HCO3)2. It is rarely found primarily in erectile rocks, especially in pegmatites. It is usually a secondary mineral. There are plenty in the country. It is usually the main component of carbonated sedimentary rocks (eg limestones) and marbles. It is processed in various forms and used as filling material in paint, paper, plastic sector. Calcite used in the plastic industry; There are 2 types, covered and uncoated.
