UV Absorber UV-P Chemical Name: *-(2'-Hydroxy*5'-methylphenyl)-benzotriazole CAS No. : ********4 Molecular Formula: C*3H*1N3O Molecular Weight: **5.*5 Solubility: UV-P is particularly effective in styrenic polymers, PVC, unsaturated polyesters, polyurethanes, acrylic polymers and polycarbonates. Attribute: white to yellowish crystal powder Property Specification Appearance white to yellowish crystal powder Melting Point **9 ***2 Deg. C Assay *9% min (HPLC) Transmittance(**0nm) *7% min (**0nm) *8% min Ash content 0.3% max Applications: UV-P is a benzotriazole type UV absorber. Characterized by its strong, broad range UV absorption property, UV-P brings an excellent photostability to polymers against UV light exposure in many ways ***** retarding color yellowing , preventing embrittlement, maintaining of mechanical properties etc. * Styrenic polymers: 0.**0.5wt% for PS based on polymer wt. 0.**0.5wt% for ABS based on polymer wt. 0.**2.0wt% for HIPS based on polymer wt. * Polyvinyl chloride: 0.**0.5wt% for PVC based on polymer wt. * Polyurethane: 0.**1.0wt% for PS based on polymer wt. * Polyacrylate: 0.***0.3wt% for PS based on polymer wt. * Polycarbonate: 0.***0.3wt% for PS based on polymer wt. * Unsturated Polyester: 0.**0.4wt% for PS based on polymer wt. ADVANTAGE * Very high photostability for its strong ability to absorb light especially in UV region(******0nm) * Odorless, does not bring smells to the polymers. * Very stable to heat, and can be used in plastics which require high processing temperature. * Low vapor pressure, very little or no loss during processing. TOXICITY & SAFETY UV-P can be safely handled without irritation caused to the skin. Stability and Storage: In a closed system and dry, dark place without any light exposure. Package: In *5 kg carton drum with inner plastic bag Optional Information - HS Code : ***3 Heterocyclic Compounds With Nitrogen, Nucleic Acids, Their Salts
