The production level of domestic metallocene polypropylene is gradually approaching the world advanced level

China's metallocene polypropylene production level is gradually approaching the world's advanced level
.

At present, the global demand for metallocene polypropylene has exceeded 500,000 tons
.

However, this technology has long been monopolized by foreign companies such as Exxon Mobil, Dow Chemical, Basel and Mitsui Chemicals

In 2014, China Petroleum and Petrochemical Research Institute and Kazakhstan Petrochemical used the metallocene polypropylene catalyst as a breakthrough point, with the help of the development and industrial application of a new type of polypropylene catalyst in a special sub-project, and conducted joint research on metallocene transparent polypropylene products
.

After 3 years of hard work, they successfully developed a metallocene polypropylene catalyst (PMP-01)

In late June 2017, the carrier metallocene polypropylene catalyst (PMP-01) independently developed by the Petrochemical Institute was used for the first time in the 80,000 tons/year batch liquid phase bulk polypropylene plant of Harbin Petrochemical Corporation to produce highly transparent metallocene.
Polypropylene MPP6006
.

The product can be applied to packaging, film and injection molded products, etc.

On October 30, 2020, the metallocene polypropylene catalyst (MPP-S02) independently developed by China Petrochemical Institute was successfully tested in a large chemical company in Shandong
.

They developed two kinds of metallocene ultra-high melt mass flow rate polypropylene, and the technical performance of the products reached the index requirements

The metallocene catalyst is a single active center catalyst, which has the characteristics of high activity, stable polymerization reaction, and good hydrogen regulation performance

In late June 2017, Harbin Petrochemical's 80,000 tons/year batch liquid phase bulk polypropylene plant was used for the first time to produce high-transparent metallocene polypropylene MPP6006
.

After nearly 7 years of research, Yanshan Petrochemical successfully produced metallocene polypropylene products on March 16, 2018
.

This is the first time that China's industrialized continuous production equipment has successfully developed metallocene polypropylene, marking that Yanshan Petrochemical has become the first domestic continuous production enterprise of metallocene polypropylene

On December 16, 2020, the scientific research team of Yangzi Petrochemical Research Institute achieved a new breakthrough in the production process of metallocene polypropylene on the polypropylene pilot plant, and also realized the continuous and stable operation of metallocene polypropylene production
.

Dushanzi Petrochemical is also trying to produce metallocene polypropylene products
.

Compared with traditional polypropylene products, metallocene polypropylene has the characteristics of narrow molecular weight distribution, lower melting point, and no soluble short-chain block copolymers
.

The product prepared with it has low precipitation and good sensory performance, and can be used in the fields of medical and health and food packaging.

The metallocene polypropylene produced by the metallocene catalyst also has small crystallites, excellent impact strength and toughness, good transparency, high gloss, good radiation resistance, excellent insulation properties, and compatibility with other resins.

Under the strong demand for masks, polypropylene meltblown materials, the raw materials for masks, can also be produced using metallocene catalysts
