Application:
>Features: high molecular weight hindered amine light stabilizer (HALS). excellent compatibility, good resistance to extraction, and low volatility.
>944 applications include polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers. It imparts excellent light stability to thin articles, particularly fibers and films. In thick cross sections, it is specifically suitable for polyethylene articles.
>Sulphur or halogen type may affect UV-944 effect when exists.
>It’s concentrations range between 0.1 % and 2.0 %, depending on the substrate, processing conditions and application.
Handling and Safety:
>FDA cleared for use in food contact applications. It is not intended for use in products that may come in contact with mucous membranes or abraded skin or be implanted into the body.
>For additional handling and toxicological information, please consult us for Maternal Safety Date Sheet.
