Chemical name: 1,1,3-tris(2-methyl-4-hydroxyl-5-tert-butylpenhyl)butane CAS No.：1843-03-4                                Molecular formula：C37H52O3 Molecular weight：544.82                                                                                                              Appearance: White powder Melting range，℃：181 – 190 Loss on heating，%：3.0 max. Ash content, %：0.05 max. Fe content, 10-6: 20 max. Color value, APHA:  100 max. Grain size (1mm): 100%                                                             ANTIOXIDANT HONOX-CA is a high efficient phenolic antioxidant. It used as stabilizer and antioxidant for polymers (PS,PP,PE,PVC,PAN,ABS and fiber plastics). It has low volatility, no pollution，discoloration and it won’t decompose under high temperature process. It can improve the heat resistance and oxygen resistance of the products significantly. Additionally, it can inhibit copper damage and apply in polyolefin cable production. The synergism will be realized when it is combined to use with DLTDP, DSTDP and UV absorber. info at hhochem. com
