Croda Polymer Additives has launched a new type of inorganic ultraviolet absorber.
The Goole, England, company says its Solasorb series delivers high UV protection and improved transparency compared to conventional nano-powders.
Solasorb is based on ultrafine metal oxides that allow greater dispersion and clarity. Unlike conventional organic UV absorbers, the new Croda materials have low migration and long-term UV protection. Croda makes Solasorb using patented technology.
Croda is aiming Solasorb at clear film and bottle applications. Such packaging can protect against the harmful effects of UV light, improving shelf appeal and protecting nutritional values. The product is available in a fully dispersed liquid form or in a polymer carrier suitable for polyethylene and polypropylene.
