Polypropylene feature and it use in different application The polypropylene is a thermoplastic polymer. It is used in a wide variety of applications like in Plywood industry, stationery, plastic parts and reusable containers of various types, Laboratory equipment, and most recently in the construction industry. In addition to a polymer made from propylene monomer, is resistant to many chemical solvents, bases and acids. The polypropyleneIt is a type of plastic that can be molded with heating only, that is, it is a thermoplastic. It has properties similar to polyethylene (PE), but with a higher softening point. Main features polypropylene: of the Low cost PETG Sheet; High chemical resistance to solvents; Easy molding prismatic sheet; Easy to color; High resistance to fracture due to flexion or fatigue; Good impact resistance superior to temperatures above 15 ° C; Good thermal stability; Increased sensitivity to UV light and oxidizing agents, suffering degradation more easily. Production of film The polypropylene processing can be achieved through molding and extrusion. The most common technique is injection molding, which is used to obtain parts such as glasses, PVC Rod, cutlery, cups, lids, containers, household utensils and automobile parts, such as batteries. Related techniques of blow molding and injection-blow molding and stretching are also used, which involve both extrusion and molding. Advantages and disadvantages of polypropylene Polypropylene has many advantages: it is cheap, usable in the food industry (it is odorless and non-toxic), very resistant to fatigue and bending, very dense, chemically inert, sterilizable and recyclable. It is an excellent electrical insulator. Disadvantages: It is fragile at low temperature, sensitive to UV rays, less resistant to oxidation than polyethylene and difficult to stick. The polypropylene strength can be improved by mixing with EPR or EPDM elastomers. Its mass production is a source of environmental impacts and oil consumption and emissions, flame retardants) can make it difficult or impossible to recycle profitably. The progress of ecological design in plastics could facilitate the classification and recycling of this material. Applications: some of the uses of polypropylene: Toys; Boomerangs; Plastic cups; The containers for food, medicines, chemical products; Clothing and appliances; Fibers; Corkscrew Carpets; Polypropylene Sheet syringe for injection Synthetic meadow Bags and Bags Sterilized hospital supplies; Building materials made in autoclaves; Auto parts (fenders, pedals, battery covers, interior upholstery, lamps, fans, blowers and other various pieces). Parts for washing machines. Some of the innovative applications of polypropylene in construction are the innovative construction systems that allow homes to be made from modules or polypropylene containers that can be stacked to expand the space. Modular system of construction of houses made of Plastic Prototyping that is assembled to assemble modules and houses through the connection with screws. The panels are made of recycled polyethylene and polypropylene and are lightweight, durable and low cost. One-story houses can be put together to build any surface the house is necessary for a family. Currently there is a tendency to only use PP inside cars. This would facilitate the recycling of waste material at the time of the vehicle, since it is known what material it is.
