Antioxiant With Three Functional Groups
Chemical name:1,3,5-Tris(3,5-di-tert-butyl-4-hydroxy benzyl)-s-triazine-2,4,6-(1H,3H,5H)trione
Physical Properties: White Crystalline Powder Assay: ≥98% Melting range: 218-224℃ Ash: ≤0.006% Light Transmittance:425nm≥95% ,500nm≥97% Volatiles: ≤0.5%
Introduction: The product is soluble in solvents like acetone,chloroform and amide, and insoluble in alkane and alcohols. Flash point:289.4℃kindling point:302℃.
Applications:The product is a kind of tri-function group phenolic antioxidant, without pollution and coloring up. Dependent on high molecular weight and melting point, it has low volatility, low transferring,and good water extraction resistance, white equips plastics with resistance to thermo-oxidation and light-oxidant. AT-3114 suits for PE,PP,PS,ABS,nylon,PVC,PU,cellulose and synthetic rubber, especially effective for polyolefin.When used with UV absorbent and phosphite ester,a synergistic effect can be reached, thus enhancing the thermo-stability and light stability.
This product can be used to contact food polyolefin products(contact fatty and non-fatty foods).The photo-thermal stability can be further improved by synergism with UV absorber or phosphates.It can prevent the aging of the polymer by heat and oxidation, and also has anti-light property. It is mainly used as an antioxidant for polypropylene and polyethylene, which has the functions of heat and light stabilization. There are synergistic effects with photostabilizers and adjuvant antioxidants. The product is low in toxicity. POLYOLEFIN products available for food exposure at a dosage not exceeding 15 % of the main materials.
