Tiangang® UV-360

Very Low Volatile Benzotriazole UV Absorber 

Chemical name 2,2'-methylenebis(6-(2H-benzotriazol-2-yl)-4-1,1,3,3-tetramethylbutyl)phenol)
CAS number 103597-45-1
Molecular Weight 659 g/mol
Description Tiangang® UV-360 is a benzotriazole UV absorber, particularly suitable for complex moldings, fibers, sheets, twin wall sheets, thin films, adhesive layers and laminated or co-extruded semi-finished parts, where high loads, low volatility and good compatibility are required to achieve high UV-screen performance and minimize sublimation through vents and prevention of deposits on molds, chill-rolls or calibrators.
Its applications include acrylic resins, polyalkylene terephthalates, polycarbonates, modified polyphenylene ether or sulfide compounds, polyamides, polyacetals, polyolefins, styrenics, elastomers and high performance plastics.
