Polypropylene is one of the most widely used and basic polymers used in the world. Polypropylene The polymerization of propylene is performed at relatively mild temperatures and pressures in the presence of the famous Ziegler-Nata catalyst. The presence of this catalyst forms an isotactic polymer that is able to crystallize up to about 90%.
Its characteristics include tensile strength, low density, colorlessness, hardness, resistance to acid, base and solvents. Its low production cost compared to other thermoplastics creates a special place for PP polypropylene in the industry. has done
