Polypropylene (PP) is a tough, rigid, and crystalline thermoplastic. It is made from propene (or propylene) monomer. This linear hydrocarbon resin is the lightest polymer among all commodity plastics. PP comes either as homopolymer or as copolymer and can be greatly boosted with additives. Polypropylene also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance.

1. In 2022, my country will become the largest oil refining country in the world; 2. The basic petrochemical raw materials are still in the peak production period; 3. The capacity utilization rate of some basic chemical raw materials has been improved; 4. The prosperity of the fertilizer industry has rebounded; 5. Modern coal chemical industry ushered in development opportunities; 6. Polyolefin and polycarbon are at the peak of capacity expansion; 7. Serious overcapacity of synthetic rubber; 8. The increase in my country's polyurethane exports keeps the operating rate of the device at a high level; 9. Both the supply and demand of lithium iron phosphate are growing rapidly.

At about 12:45 on June 8, a spherical tank pump of Maoming Petrochemical and chemical division leaked, causing the intermediate tank of aromatics unit of ethylene cracking unit to catch fire. It is understood that the fault involves 2# cracking unit. At present, 250000 T / a 2# LDPE unit has been shut down, and the start-up time is to be determined. Polyethylene grades: 2426h, 2426k, 2520d, etc. In addition, the start-up time of 1# cracking, which was originally scheduled to start on June 9, is to be determined. LDPE device involves grades 951-000, 951-050, 1850a, etc.

At present, the sources of raw materials and waste packages of three major recycled polymers, recycled PET (RPET), recycled polyethylene (R-PE) and recycled polypropylene (r-pp), are limited to a certain extent. In addition to energy and transportation costs, the shortage and high price of waste packages have driven the value of renewable polyolefins to a record high in Europe, resulting in an increasingly serious disconnect between the prices of new polyolefin materials and renewable polyolefins, which has existed in the r-PET food grade pellet Market for more than a decade.
