-PP futures in China fell by 1.4% amid a sharp decline in commodity prices

China’s polypropylene (PP) futures fell 1.4% on May 19, ICIS reported, citing data from the Dalyan Mercantile Exchange (DCE).

Thus, pp futures for September 2022, the most actively traded on DCE, on May 19 were at the level of CNY 8,493 (USD1,312) per ton, which is CNY122 per ton below the level of approval of the previous day.

According to DCE, about 2.5 million tons of polypropylene were sold on Thursday with delivery in September 2022. Polymer-Processing – Recycling-polypropylene

Polypropylene futures prices fell due to a drop in coal futures (a decrease of 1.3%), while more spot transactions were concluded than a day earlier.

Earlier it was reported that the Chinese company Ningbo Kingfa Advanced Materials on May 12 resumed production at the propane dehydrogenation plant in Ningbo (Ningbo, Zhejiang Province, China) after carrying out planned preventive measures. Repair work at this installation with a capacity of 600 thousand tons of propylene per year was started on April 21 of this year.

-Kuraray to increase June prices of polyester staple fiber

Kuraray announces its decision to increase the prices of polyester staple fiber, for shipments commencing June 1, 2022, said the company.

In addition to the significant increase in the cost of key raw materials and utilities resulting from a rise in crude oil prices, Kuraray’s earnings continue to experience pressure from soaring logistics and manufacturing costs, the rapid depreciation of the yen, associated with increased costs for facility maintenance and renewal, which are beyond the scope of cost absorption through the Company’s internal efforts.

Under these circumstances, Kuraray has decided to implement the price revisions set out below to improve profitability and to maintain a steady supply.

As per MRC, Kuraray Co., Ltd. (Tokyo, Japan) has announced its decision to divest operations related to UV-based water treatment and ballast water treatment run by Calgon Carbon Corporation, a Group subsidiary based in the United States.

The divested operations will be transferred to De Nora Water Technologies LLC in Italy. Polymer-Processing – Recycling-polypropylene

As MRC informed before, Kuraray America, a subsidiary of the Kuraray Group and one of the leading international companies in the production of specialty chemicals, fibers, resins and elastomers, has resumed operations at its vinyl acetate monomer (VAM) plant in La Porte, Texas, USA. This plant with the capacity of 335,000 mt/year was shut in mid-February because of the unprecedently low temperatures in the region and restarted on 2 April, 2021.

-The Use of Plastic Gears in Industries

In an article recently published in the open-access journal Polymers, researchers discussed the service and wear life of 3D printed polymeric gears.


In recent years, additive manufacturing has surpassed traditional manufacturing methods in popularity. The most significant downside of additive manufacturing is that it takes longer to produce than traditional manufacturing methods and is not ideal for large production. With a little investment, it is feasible to make goods that have been modeled with a three-dimensional (3D) printer.

Because of their lightness, low cost, corrosion resistance, and silent operation, plastic gears are commonly employed in the electrical, culinary, and textile sectors. The strength of plastic gears printed in three-dimensional printers was investigated by researchers. The mechanical properties of gears created using the 3D printing approach have been investigated both theoretically and empirically under various working situations.

About the Study

In this study, the authors calculated the wear resistance of plastic spur gears made using the fused deposition modeling (FDM) method theoretically. Wear tests were performed in the Forschungsstelle für Zahnrader und Getriebebau (FZG) type test equipment at the same load and rotational speeds to assess the service life of gears. Gears were made from thermoplastic polymer materials such as acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), and polyethylene terephthalate (PETG).

The team determined the wear of plastic gears generated by the FDM process in 3D printers theoretically based on the number of rotations. MATLAB® was used to calculate the equation that was used to describe wear along the line of action.

The researchers evaluated the gears’ service life by repeating the tests with the same load and rotating speeds. PLA, ABS, and PETG polymeric thermoplastic materials were used, which are often utilized in the FDM process. Plastic gears were printed using a BCN 3D Sigma R19 three-dimensional printer. Wear testing was performed with the FZG closed-circuit wear test instrument to observe the wear on the gears.

Complete recycling lines for post-consumer and industrial textile waste to produce fibres for re-spinning and/or nonwoven end-uses are one focus of this product range. Customer awareness and regulations are forcing clothing brands to recycle their textile waste in their own products. Recycled fibers can also be used in the nonwovens industry for various applications, for example in the automotive industry, for insulation, mattresses, and furniture felts.

Andritz Laroche offers a complete process range of tearing lines from 50 up to 3,000 kg/h, which can be used for almost all types of pre/post-consumer textile waste. The aim is to preserve the character of the original fibers, for example cotton, by maximizing fiber length, strength and feel.
