What Is Light Stabilizer-944?
UV-944 is a high molecular weight hindered amine light stabilizer with excellent compatibility, extraction resistance and low volatility. Feature of light stabilizer 944 are high molecular weight hindered amine light stabilizer, excellent compatibility, good resistance to extraction and low volatility.
Light Stabilizer-944 Usage
1.HALS 944 application 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.
2. HALS 944 Used in polyoxymethylene (POM), polyamide (PA), polyurethane (PU), soft and hard PVC and PVC blends.
3. HALS 944 Usedon styrene elastomers and stickies
4. Sulphur or halogen type may affect UV-944 effect when exists.
5. It’s concentrations range between 0.1 % and 2.0 %, depending on the substrate, processing conditions and application.
