Australian alumina ban disrupts Rusal production -- Australia's ban on exports of alumina and aluminium ore to Russia, including bauxite, will further disrupt supply chains and production at leading aluminium producer Rusal, consultancy Wood Mackenzie said on Monday.
The Australian government announced the ban on Sunday as part of its ongoing sanctions against Moscow for its aggression in Ukraine, saying Russia relies on it to meet one-fifth of its alumina needs. WoodMac senior manager Uday Patel said in a statement that the ban would make it difficult for Rusal to maintain normal primary aluminum production.
Rusal said it was assessing the impact of Australia's move and would make further announcements if necessary. "It is increasingly likely that UC Rusal's only option for alumina procurement will be through a Chinese entity." The Australian alumina ban has also had an impact on foaming agent prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.
Introduction to Protein Foaming Agents
Protein foaming agents are produced from naturally hydrolyzed proteins. They are combined with foam stabilizers (metal salts), fungicides, corrosion inhibitors, antifreeze additives and solvents to form foam concentrates. In some more advanced protein based foam agents, like fluoroprotein foams (FP) and film forming fluoro protein foams (FFFP), fluorochemical additives are added to improve the performance of the foam.
Performance of Protein Foaming Agents
Foam formed by protein based foaming agents are very stable with a high heat resistance and good burnback resistance. Due to the excellent foam stability, the poured foam cement can reach more than 1.5 meters without collapse. Therefore, protein foaming agents are suitable for the production of foamed brick, light plate and light wall.
Compared with the vegetable foaming agents, the form cement made by protein foaming agents has better sealing performance and heat preservation performance, and higher strength.
Applications of Protein Foaming Agents
Protein foaming agents are widely used for building roof insulation, floor heating and industrial pipe insulation.
Besides, due to the characteristics of high heat and good burnback resistance, protein foams are often used for hydrocarbon fuels by the petroleum industry, such as various of crude oils, gasolines, diesel fuels and jet fuels.

Since February, gold has enjoyed a smooth upward run on the back of surging US inflation and the brewing of war. While expectations of rate rises have also risen in tandem over this period, gold had been largely pre-priced and the underlying driver of tightening expectations had come from inflation continuing to rise to record highs. The risk aversion caused by the continued tension in the war also provided an important short-term support for gold. This will have a certain impact on the price of the foaming agent and the market of the foaming agent.
