Polyurethanes are subject to degradation under UV light and thermal exposure, resulting in discoloration, yellowing and loss of physical properties. Even in storage, polyurethane might still interact with Nox, ending up yellowing and shorter service life of products. Everlight Chemical presents a series of additive solutions to protect polyurethane products from light and heat degradation, improving UV and thermal stability, extending service life of polyurethane products.
