Chemical Name: 2-(2'-Hydroxy-5'-methylphenyl)-benzotriazole CAS No. : 2440-22-4 Molecular Formula: C13H11N3O Molecular Weight: 225.25 Structural Formula:
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 129 -132 Deg. C Assay 99% min (HPLC) Transmittance(440nm) 97% min (500nm) 98% 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 i.e. retarding color yellowing , preventing embrittlement, maintaining of mechanical properties etc. * Styrenic polymers: 0.2-0.5wt% for PS based on polymer wt. 0.3-0.5wt% for ABS based on polymer wt. 0.5-2.0wt% for HIPS based on polymer wt. * Polyvinyl chloride: 0.2-0.5wt% for PVC based on polymer wt. * Polyurethane: 0.3-1.0wt% for PS based on polymer wt. * Polyacrylate: 0.15-0.3wt% for PS based on polymer wt. * Polycarbonate: 0.15-0.3wt% for PS based on polymer wt. * Unsturated Polyester: 0.2-0.4wt% for PS based on polymer wt.
ADVANTAGE * Very high photostability for its strong ability to absorb light especially in UV region(270-340nm) * 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.
