Non Toxic Sulfur Antioxidant For Oil Additives ISO9001 Certification
Features:
White crystalline powder. Melting point 63-69 ° C. Soluble in benzene, chloroform, carbon disulfide and carbon tetrachloride, insoluble in dimethylformamide and toluene insoluble in acetone, ethanol and water.
White granular material, molecular weight 683, melting point 63 ° C, acid value ≤ 0.05 mg KOH / g, soluble in solvents such as benzene, acetone or toluene. This product has excellent decomposing peroxide function and can be used as auxiliary antioxidant for PE, PP, PVC, ABS resin, synthetic rubber and grease. It is especially suitable for long-term thermo-oxidative aging protection of resins such as polyolefins because it can revitalize the phenolic primary antioxidants used together. It is non-polluting, non-staining, and low in volatility. It has good synergistic effect with phenolic antioxidants (such as 264, 1010, 1076, 1098, 1790, CA, etc.) or UV absorbers. The general dosage is 0.05-0.5%.
Packaging:
25kg/ PE Drum, 180kg/drum
Storage: Store in a dry, dark, sealed container and avoid storage below 0 °C.
Applications
1. Polyolefin: DSTDP is an effective stabilizer in polyolefins, especially in PP and HDPE, usually mixed with phenolic antioxidants, which can enhance aging stability and light stability. In most cases, the effect of compounding is better than using the primary antioxidant alone, and the initial color of the material will improve. The effect of the compound addition depends mainly on the mixing ratio of the phenolic antioxidant to the DSTDP (which can be compounded according to requirements from 1:1 to 1:6) and the structure of the phenolic antioxidant. Recommended dosage: 0.05~0.1%.
2. HIPS and ABS: DSTDP is especially suitable for the stabilization of HIPS and ABS resins, and also improves the use of phenolic antioxidants. Recommended dosage: 0.2~1%.
3, other applications: DSTDP can also be applied to animal and vegetable oils, lubricants (oil), fat, paraffin, soap and other organic compounds.
