PP

PP or polypropylene is a synthetic thermoplastic polymer belonging to the category of polyolefins. It is a white solid product. PP is obtained by propylene polymerization technology using metallocene catalysts. Polypropylene is produced under pressure of 10 atm.

Main PP qualities:

1. Low moisture absorption. The substance is characterized by good electrical insulating qualities over a wide temperature range.
2. High resistance to alkalis and acids. Polypropylene is resistant to the destructive effects of salt solutions and other inorganic media.
3. Good mechanical properties. High rigidity is one of the main features of the material.
4. Low wear resistance and ease of processing.

Polymeric materials are widely used in various sectors of the economy. PP is used in electrical engineering, medicine, in the manufacture of instruments, vehicles and other areas.

The main reason for the popularity of polypropylene plastic in the industry can be called the expansion of its areas of use due to the displacement of lower quality polymers. PP replaces PVC with polystyrene. This is due to the non-toxicity of the material, so it is considered more environmentally friendly, while being much lighter and recyclable.

In terms of availability, polypropylene also wins. Due to its low cost, PP is used in the production and assembly of electronics, the manufacture of polymer fibers and threads. Increased wear resistance allows the use of polypropylene not only in the automotive industry, but also in mechanical engineering and construction.
