Chemical name: 2',4'-di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate Physical Properties: Appearance: White crystalline powder Melting point (C): 192.0-197.0 Heating loss (%): <0.50 Ash (%): <0.10 Molecular Weight: 438.7 CAS registry: 4221-80-1 FDA Section: 178.2010 Package: 50kg or 100kg fiber drum Feature and Use: Although it absorbs short wave UV light (λmax 267nm), its structure will change to Benzophenone after photo-Fries rearrangement, and it works well as UV absorber. Works synergistically in combination with Hindered Amine Light Stabilizer and exhibits an excellent performance. Suitable for almost all synthetic resins, especially for PE and PP.
