According to BASF, Uvinul 3030 has unusuallyhigh thermal stability and low volatility, makingit highly suitable for use in plastics that areprocessed at high temperatures, such as polycar-bonate, polyethylene terephthalate and polyethersulfone. Excellent compatibility with polycar-bonate also means it is ideal for high-transparen-cy applications, such as window panes.

In other news, BASF reported sales growth of7.2% for the first quarter of 2003, while incomefrom operations before special items rose by15.4%. The sales climb was due to significantincrease in volumes, particularly for theChemicals and Plastics & Fibers segments, and ahigh oil price.
