Polypropylene (PP) is a white granular polymer - product of the polymerization of propylene. Among all plastics it has the lowest density of 0.90 g/cm3, is resistant to abrasion, is almost not exposed to corrosion spreading and more heat-resistant than polyethylene. However, polypropylene has greater sensitivity to light and oxygen, which decreases with introduction of stabilizers.
There are such main types of polypropylene as homopolymer, block copolymer and random copolymer.
Homo-polymer of propylene (homo-PP) has a crystalline structure. The main advantage of homo-PP is the presence of highly hard mechanical properties. Homo-polymer has high stiffness, but at low temperatures it becomes very fragile. At low temperatures, it is recommended to use the block copolymer.
Block copolymer (block-PP) is characterized by improved impact resistance, which explains the increased frost resistance of the material. Improving the impact resistance is accompanied by decrease in hardness and stiffness of the material.
Random-copolymer (random-PP) has good insulating properties, although slightly worse than the homo-polymer and, especially the block copolymer, but these properties are maintained in a wider temperature range. Mechanical properties of random copolymer have an intermediate position between homo - and block-copolymers, characterized by a balance of stiffness and impact resistance.
Processing of polypropylene is implemented by means of injection molding, film blowing, sheet extrusion, blow molding extrusion, injection blow molding, injection molding, compression molding.
The main products of polypropylene: films, pipes, bags, items of technical equipment and vehicles, household items, non-woven materials.
