Details:	Chemical Name: Tri nonyl phenyl phosphite (TNPP) Molecular Formula: C45H69O3P or (C9H19C6H4O)3P Molecular Weight: 688 CAS No.: 26523-78-4 Specification: Appearance: Colorless or light yellow transparent viscous fluid Hue (Gardner or APHA) ≤ Gardner 2 or APHA 100 Content of phosphor %: 3.8 - 4.5 Degree of acidity mgKOH/g ≤ : 0.3 Refractive index: 1.5230-1.5280 Viscosity 25 Pas: 2.5-5.0 Density 25 g/cm3: 0.9800-0.9920 Application: This antioxidant has the characteristics of nonpolluting, heatproof, which is applied by the rubber-plastic elastomer of SBS, TPR, IPS, PVE, PE, PP and ABS etc, because of its high stability of thermal oxidant, not fading during operating and processing, special suitable for the use as non-fading stabilizer without influence to the color of products. Therefore, it is widely applied by the products in white of bright colors, another characteristics is that the antioxidant can increase the heat resistance and the resistance to oxidation and to prevent the resinification phenomena of polymer during its processing and storing as well as to inhibit from the phenomena of gelling and viscosity-increasing and to prevent the thermal oxidative aging and yellowing of rubber-plastic products as well. Packing: Net 200kgs galvanized iron drums or net 1000kgs IBC containers or as the buyers request.
