Alcan to double production of superfine ATH
June 1997
outside Japan because of the strength of the Japense ‘Yen and the need to be closer to its European customers, from whom there is a growing demand. If the project is sanctioned, the plant will be built at Veendam, alongside the Nedmag Industries magnesium oxide plant (which will supply feedstock extracted from local deposits of magnesium salt). Investment will be about NLG 70 million ($47 m) and the plant will come into operation in 1999. It will produce synthetic hydrotalcite initially, with magnesium hydroxide in a second phase. According to Kyowa, synthetic hydrotalcite, Mg,Al,(OH),,CO,.4H,O, can be used as a halogen scavenger in polymers and as a PVC stabilizer It has three times the acid neutralizing capacity of calcium stearate but does not suffelr from water carry-over or stearate bleed. ThLecompany has been a leading producer of magnesium hydroxide, and the planned investment could signal an intention to return to world top-level ranking. Contact: Kyowa Chemical Industry Co.

Alcan to double production of superfine ATH Over 520 million will be invested over the next 2-3 years by Alcan Chemicals Europe in more than doubling its production of Superfine alumina trihydrate powders at the plant at Burntisland, Scotland. These are widely used as flame retardant additives and smoke suppressants in plastics and rubbers. The decision follows a major strategic review by Alcan Chemicals in conjunction with its parent, the Canadian group, Alcan Alminium Ltd. ‘The objective is to strengthen market position and substantially increase world market sh.are, with the ultimate aim of being the lowest-cost producer in the world. Alumina trihydrates are tine white powders, produced with close control over particle

size and shape. When incorporated in thermoplastic cable sheathing they will delay onset of burning and, in the event of tire, will reduce emissions of smoke and toxic fumes. Damage to electrical and electronics components from acid gas emissions is also limited. Alcan reports growth of its product has been especially strong in electrical transmission applications, where the potential cost of fire damage is substantial. There are also widespread applications in thermosetting compounds, where the additive also allows a high standard of surface finish to be achieved.

Ciba and Great Lakes resolve TB Blends patent dispute The six-year dispute between Ciba Specialty Chemicals and Great Lakes Chemical Corporation regarding an additive which imcolour resistance of polyolefin proves systems has been settled. It was inherited by Great Lakes when the company purchased the polymer additives and associated speciality chemicals business of EniChem Synthesis SpA, in April 1994. Ciba had earlier filed a suit against EniChem alleging that its TB-Blends - a unique combination of phosphites, phenolic antioxidants and thioester - infringed its own European patent. Great Lakes was granted an application patent for them in the USA in 1992. Great Lakes’ Polymer Stabilizers business unit produces and markets antioxidants and ultraviolet stabilizers incorporated in a range of polymer systems with wide-ranging applications The parent company is the world’s leading producer of certain speciality chemicals for applications such as polymer stabilizers, flame retardants and other products.
