Detailed Description
Yiphos 3032 is a high-efficiency phosphite antioxidant. Appearance: Clear colorless liquid Active Content, %: ≥98 Density, g/ml (25℃): 1.305-1.315 Refractive Index, (25℃): 1.5100-1.5180 Solubility(g/100 g solvent)@25℃ Water <0.01 Methanol <0.1 Toluene >50 The higher active phosphorus content, the less dosage; Hard to decompose at high temperature, superior thermal resistance; Good hydrolysis resistance to avoid the coking; Outstanding color improvement and long-term stability. Yiphos 3032 is widely used in all kinds of applications. The heat stability is superior when at 1/3 dosage of TPP because of the higher active phosphorus content, consequently it can replace the traditional phosphite antioxidants. Yiphos 3032 can not only protect the heat stability of the polymers during the processing and the synthesis, for example, prohibit the color change, maintain the transparency of the product; but also improve the weatherability of the polymers greatly so that their temperature resistance is superior and their storage stability is improved during the processing in the later stage. The effect is excellent in the PVC products, Polyether polyol, Epoxy resins, Unsaturated resins, Polyurethane etc. The advantages are as below when compared to Yiphos 3010 (Weston 600/ Doverphos 1220): 1, Low odor, clear liquid 2, Hydrolysis resistance (no hydrolysis residue) The advantages are as followed when compared with the traditional phosphite antioxidants: 1, No phenol 2, Low dosage: The effect is superior to TNPP / TPP while the dosage is only 1/3 of them.
