1.Chemical name: Bis (2,2,6,6-tetra methyl-4-piperidyl) sebacate Chemical Formula: C28H52O4N2 Structure: Molecular weight: 480.8 CAS NO.: 52829-07-9 2. General Specification: Appearance: white powder crystalline Melting point: 80-86degrees centigrade Content: 99% min ASH: 0.1% max Loss on Drying: 0.5% max Transmission: (10g/100ml toluene) 425nm≥98% 500nm≥99% 3.Uses: Samsorb 770 is sued as photostabilizer for PP, HDPE, ABS resin, PMMA, SAN, PVC, nylon, polyester, POM, etc. It has excellent light stabilization than others. Heat resistance can be improved when it's used with antioxidant. It can further improve photo stabilization in combination with UV absorber. And lightfast effect won't be reduced, using with paint. Its dosage is 0.1-0.5% based on polymer weight. Otherwise, it can preserve macromolecule products, such as PU, Polystyrene, Polyamide, coating, adhesive, rubber, etc. 4.Packing and Storage: Nontoxic, non-flammable, non-explosive, non-corrosive and good storage stability. Cardboard drum inner lining plastic bag, each drum 25kg net weight. Or according to customers' requirements
