Weight reduction as a means of conserving our resources is a fundamental constituent in the contemporary design and dimensioning of technical components in many industries, and particularly so in the automotive and aviation sectors. Polyamides with reinforcing materials such as glass fibres, carbon fibres and minerals are becoming increasingly important in the automotive industry above all. Using the LUVOBATCH PA BA 1001/1002 blowing agent system, it is now possible to reduce the weight of these materials by up to 30% and simultaneously maintain the loss of mechanical properties at a low level. As an example, foamed components produced with this system exhibited a performance factor for bending stress in the range from 1 to 1.3. Consequently, the change in flexural strength is smaller than the reduction in weight.
In addition to reducing weight, this endothermic blowing agent system specially adapted to polyamides enables sink marks and contraction cavities to be avoided. Delamination in components subject to high mechanical stress, which may arise during the addition of masterbatch based on polyethylene or universal carriers, is reduced or prevented by the use of a special polyamide as the carrier system in LUVOBATCH PA BA 1001/1002. The system can be used in all common processing techniques.
