NEW DEVELOPMENTS IN STABILIZER SYSTEMS FOR FLEXIBLE POLYURETHANE INTEGRAL SKIN APPLICATIONS

摘要

UV resistance and thermal stability have always been key performance requirements for flexible polyurethane integral skin foam. A good combination of these two properties, along with low fogging characteristics, is especially important in the wide and fast growing field of (interior) automotive applications. In contrast, for outdoor uses such as shoe soles, thermal resistance is of lesser importance and the main performance criterion is UV resistance. This paper examines the performance of two new stabilizer packages, LOWILITE~(~R)UV B1211 and LOWILITE~(~R)UV B1260, specifically designed to meet the above mentioned applications. It is shown that LOWILITE~(~R)UV B1211 is preferably for interior automotive integral foam applications, while LOW1LITE~(~R)UV B1260 gives a superior protection in outdoor applications. Both systems give superior performance compared to the commercially available products used as comparisons.
