BLS 531 is extremely effective ultraviolet light absorber for plastics and other organic polymers.
Due to its highly effective broad UV absorption properties and excellent polymer compatibility, BLS 531 offers maximum polymer protection and low color contribution, retards yellowing, and loss of physical properties.
BLS 531 is recommended for polypropylene, polyethylene, PVC, acrylics, polycarbonate, EVA, and polyester.
BLS 531 is also recommended for use in adhesives and sealants where light stability is a concern |
