Polypropylene is a synthetic thermoplastic non-polar polymer from the class of polyolefins. It is a white solid substance obtained industrially through the polymerization of propylene at medium and low pressures and the obligatory presence of organometallic catalysts. As a result of the copolymerization of ethylene and propylene, propylene copolymers are obtained.
Area of use:
Polypropylene is a synthetic material, that is, a material produced artificially, using oil, coal and natural gas as a raw material. Due to the transformation of these substances, chemical compounds are obtained, the structure of which determines the specific properties of materials widely used in industry.
Polypropylene is formed after polymerization of propylene. In addition, the production technology of this substance allows to obtain propylene with different properties.
Recently, polypropylene, thanks to a wide range of modified materials based on it, the environmental cleanliness of products, the technological efficiency of their utilization and processing, displaces from the world market shock-resistant polystyrene, ABS plastics and polyvinyl chloride plastics. Polypropylene was able to get into all the dominant economic sectors: electrical engineering, electronics, construction, automotive, engineering, transport, instrument making, medicine, and many others. To date, polypropylene in terms of production growth is unrivaled, and this is despite the fact that the entire technical and scientific potential of this polymer has not yet been realized.
Polypropylene is most widely used in the following areas:
– anticorrosive material
– mechanical engineering
Due to its technological and consumer qualities, polypropylene has a fairly wide range of applications and occupies 20.5 percent of world production, i.e. second place after polyethylene.
Polypropylene is intended for the production of: wraps, fibers, tapes, non-woven and packaging materials, sheets, fittings, pipes and other household, technical and medical products.
