Title
(EN) TRANSLUCENT POLYURETHANE FOAMS
(ZH) 半透明聚氨酯泡沫材料
Abstract
(EN)
The present invention relates to specific translucent, preferably lightfast, polyurethane foams which have a high light transmission and are therefore suitable e.g. for producing translucent polyurethane foams or multilayer composite elements, for example for producing structural components, more particularly as roof elements such as strip lights and light domes, as wall elements such as a panel,in vehicles, in lamps, as furniture, as partitions and in sanitary facilities.
