How can I prevent colour change in polyurethane foam or sponge? The colour changes from yellow to dark yellow? Does anyone have any idea?
Many techniques are available.. UV absorbers or quenchers or photo-active fillers like ZnO... also there are many stabilizers available in market to mitigate yellowing.
Thank you so much.do you have any article this subject?
