Great Lakes forms flame retardant joint venture Great Lakes Chemical Corporation and Teijin Chemicals LTD are to combine their global brominated carbonate oligomer (BCO) activities as part of a joint venture to market flame retardants for various engineering polymers and blends, including polybutylene terephalate (PBT) and

polycarbonate (PC) resins for use in electronic component applications. Each party anticipates holding a 50% stake in the joint venture, to be headquartered in Japan, which is expected to commence during the second quarter of 2005. Great Lakes will be appointed exclusive sales agent for the joint

venture. Great Lakes currently manufactures brominated carbonate oligomers in its El Dorado, Arkansas, USA, facilities while Teijin produces the materials in Matsuyama, Japan. Great Lakes is a leading producer of flame retardants including bromine-, phosphorus-, and antimony-

based flame retardants and other synergists. These products protect against fire in plastics for consumer applications such as automotive, electrical, building materials and furnishings. Contact: Great Lakes Chemical Corporation Website: www.fr.greatlakes.com.

Chinese oleochemical producer starts export drive UK-based StarChem International Ltd has been appointed as agent for Chinese company Lutianhua Group for sales of Lutianhua's rape seedderived oleochemicals for use as plastics additives. StarChem also has an office in Chengdu, the capital of Sichuan province in China. Lutianhua was founded in 1959. As the biggest fertilizer producer and the largest rape seed oil based oleochemicals manufacturer in China, Lutianhua has been listed as one of the 18 chemical bases in China. It is one of China's 520 key state owned large-scale enterprises and one of China's 100 strongest chemical enterprises. The Lutianhua Group's main products for use in plastics include erucamide, oleamide, stearamide, Behenamide, erucic

the company. According to StarChem, the Lutamide range also includes secondary and bis amides that are effective at high temperatures and have good thermal stability. Lutamides EBS and EBO are used in engineering polymers, such as nylon and ABS. They are both good external PVC lubricants. Their hardness and high melting point provides good mould release and anti-blocking properties to a wide variety of polymer systems. Lutamides work through being evenly distributed through the polymer in the melt phase. As the polymer begins to cool the molecules migrate to the surface and form a thin lubricating layer. This Lutamide layer reduces the coefficient of friction between the surfaces and prevents any unwanted

acid, behenic acid and C18 unsaturated fatty acid. StarChem International adds that it stocks behenic acid, erucic acid and erucamide in Antwerp, Belgium for delivery to European buyers. Lutianhua Group's primary amides include Lutamides ER and OR, which are claimed to be effective slip agents in polyolefin films and other polymers. Lutamides SR and BR are used as anti-blocking agents, where they are often used in conjunction with inorganic anti-blocking agents, such as talc and silica, and are particularly useful when film haze, clarity and gloss are issues. Lutamide ER is the preferred primary amide for use in LDPE, LLDPE and PP film due to its good oxidative stability, low volatility and effective slip and anti-block characteristics, adds

adhesion. The range includes additives with good thermal and colour stability. All Lutamides are permitted for specific indirect food contact applications in the USA in accordance with CFR21. They are all permitted for use as additives in food contact plastics in the EEC. Lutamides can be easily added to the polymer at the processing stage, pre-compounded or included through a masterbatch, says the company. Simple manual mixing prior to processing will normally give an acceptable dispersion, although mechanical mixing is preferable. Dosage levels are around 5002000 ppm in film and 0.2-1.0% in moulding applications. Contact: StarChem International Limited Tel: +44 1892 619724 E-mail: [email protected]
