PP-based plastic waste, is cleaned after partitioning then being processed into small pieces from 16 to 20 mm and granulated through a melt extruder machine.
Polypropylene obtained from naphte that of crude oil derivatives, is a natural white material obtained by polymerization of propylene molecules (process to obtain the largest molecules by splicing of molecules)
Packaging materials like cap of detergent boxes, margarine containers, textile and food packages are produced with polypropylene which is a thermoplastic polymer. Also to be durable, due to recyclability find important uses areas in the automotive sector.
Polypropylene has very good resistance to fatigue, it is cost-effective, has a good impact resistance. Coefficient of friction is low, provides a very good electrical insulation, has good chemical resistance and is suitable for all thermoplastic processing. The melting temperature of polypropylene is around 160 degrees centigrade.
However, UV light resistance is less, shows high thermal expansion, paints and coatings are difficult, less resistance to outside weather conditions, it is clear to oxidation. Polypropylene is flammable and it interacts with chlorine containing solvents.
97% average crude oil derivatives are used for the production, availability and price situation is directly proportional to crude oil reserves and prices in the world. This means that when the oil is ended polypropylene will be ended. Synthetic carpets floor, various plastic bathroom, kitchen and office materials are produced from recycled polypropylene.
