Nylon

                Nylon was the first purely synthetic fiber, introduced by DuPont Corporation at the 1939 World's Fair in New York City. In 1927, DuPont Corporation had begun a secret development project name Fiber66. Wallace Carothers the Harvard Chemist and  Elmer Keiser Bolton is the department chemist as director. Carothers was hired to perform pure research, he worked to understand the new materials molecular structure and physical characters.

                 And he was found synthetic nylon fiber, which was very strong and also very flexible. The first application was for bristles toothbrushes. However, Du Pont's real target was silk, particularly silk stockings. It took DuPont twelve years and US$27 million to refine nylon, to synthesize and develop the industrial processes for bulk manufacture. With a major investment, it wasn't surprise that Du Pont spared little expense to promote nylon after its introduction, creating a public sensation, or "nylon mania".

                   Nylon was stop at the end 1941 because of America had World War II. After 1946 DuPont Corporation was promote Nylon again to public .Nylons still important plastics, and not just for use in fabrics. In its bulk form it is very wear resistant, particularly if oil-impregnated, and it used to build gears, plain bearings, valve seats, seals and because of good heat-resistance, increasingly for under-the-hood applications in cars, and other mechanical parts.

Polyvinyl chloride

         Polyvinyl chloride, commonly abbreviated PVC, is the third-most widely produced plastic, after polyethylene and polypropylene. PVC or Polyvinyl chloride has a stiff resistance properties, strong, heat and weather, the nature of the recommended use for pipes, ditches, walls, enclosures for computers and other electronic equipment. PVC can also be softened through a chemical process, and at the present time can be used in the form of shrink-wrap, food packaging, and rain gear (raincoats).
form Pure polyvinyl chloride is a white, brittle solid. this things insoluble in alcohol, but slightly soluble in tetrahydrofuran.

          In 1835 PVC was found by French chemist Henri Victor Regnault and then in 1872 by German chemist Eugen Baumann.

                The relatively low cost PVC been tested either through biological and chemical processes that lead to PVC pipes are used for disposal of waste, door frames, wire insulators, etc.

Pipe

                 Pipes, which are lightweight, low maintenance costs can be accounted for 66% in the American market are usually planted in the ground and used as a waste dump, the distribution of clean water.

Electric Cables

                   

                 PVC uses the electrical wiring is a good barrier to prevent sparks that shorted can be minimized.

Sign
 

                  Polyvinyl chloride is formed from a flat sheet with a variety of shapes and colors. usually in the form of lines of the car body.

                  

Clothing and furniture 

                  PVC has been used as well as clothes to replace materials such as leather, rubber, and latex. Besides pvc also waterproof so can be used for coats, ski equipment, jackets, aprons, and bags.

 Medical Equipment

                One-third of the medical equipment is made ​​of PVC for example scissors, knives, cutter, clamp, blood bags, etc.     

  

Flooring

               PVC can be used as flooring because besides cheap, shiny and easy maintenance suitable for homes, hospitals, offices, schools, etc.

Other Apllications

                PVC can be used on kids toys, interior clauding, custom truck troppers, green house, kids play ground, etc.
