Higher mechanical properties with lower density make polypropylene an interesting alternative to polyethylene for a large number of applications. New catalysts and production processes offer a wider range of products. Monolayer films and recycling are under development. In the meantime, China consumes almost one-third of the PP produced worldwide.

The ReOil pilot plant at OMV AG in Schwechat, Austria, converts plastic wastes with poor recycling properties into cracker raw material, and hence into potential monomers

The Danish company Plastix recycles old fishing nets and ropes. The granules produced are used by JSP International, among others, to manufacture expanded polypropylene (EPP).

11 % of the plastic waste in the sea comes from the maritime industry. For the recycling of old fishing nets and ropes, accurate sorting is very important

Weight reduction is one of the major requirements of automotive components. Regardless of the vehicles in which they are used. One of the lightest materials that can be considered is polypropylene (PP).

To ensure better stability of expanded polystyrene insulation panels on the house wall, they are fastened with an additional polypropylene (PP) anchor. However, the fact that two different materials are used results in thermal bridges due to different thermal conductivities (TC), which can be seen visually as the formation of mold and algae, but also cause energy losses. The motivation for this work was to adjust the WLF of the two materials by using a filler, but not to negatively influence the mechanical strength of the anchor.

Batteries in electric vehicles must be specially protected to counter the risk of fires. Battery trays made from aluminum frequently offer insufficient protection.

Vehicle weight reduction requirements today pose great challenges not only to automotive manufacturers and suppliers but also to material producers. The materials used must cut weight while at the same time withstanding the mechanical and chemical stresses encountered in service. This can be achieved, for example, with blends of polyamide and polypropylene. These blends also offer other useful advantages.

Until now, only metal has been used for the tailgates of VW cars. In its top of the line electric model, the ID.3, Volkswagen is now using a plastic-metal composite for the first time. One of the materials used for its production is a long glass fiber-reinforced polypropylene from Celanese. The material was required to not only satisfy the mechanical demands, but also enable an attractive appearance.

The ID.3 is Volkswagen’s first car with a tailgate made partly of plastic.

ExxonMobil Doubles PP Production at Baton Rouge

The new unit in Baton Rouge, LA/USA, increases polypropylene (PP) production capacity along the Gulf Coast by 450,000 t per year.

The new unit in Baton Rouge, LA/USA, increases polypropylene (PP) production capacity along the Gulf Coast by 450,000 t per year, meeting growing demand for high-performance, lightweight and durable plastics, particularly for automotive parts that can improve fuel efficiency and reduce vehicle emissions.

Polypropylene, a polymer with several applications, is also used to improve the safety and efficiency of everyday products like medical masks and food packaging.

“With the start-up of this new production unit, we are well positioned to responsibly meet the growing global demand for these high-performance polymers,” said Karen McKee, president of ExxonMobil Product Solutions. “The ingenuity of our people and our investments in technology enable us to produce high quality products that are essential to daily life.”

The company maintained its investments in this advantaged project through the Covid pandemic and related economic downturn. The total capital investment was more than USD 500 million. The unit started operation according to planned cost and schedule.

During construction, the project employed more than 650 workers and with full operational status, requires an additional 65 full-time ExonMobil jobs.

ExxonMobil’s integrated operations in Baton Rouge include a more than 500,000 barrel-per-day refinery, as well as chemical, lubricants, polyolefins and plastics manufacturing. The company has more than 5500 employees and contractors in the Baton Rouge area.
