Epoxy soybean oil
Properties: The product is a shallow *** viscous oily liquid at room temperature. The molecular formula C57H106O10 has a molecular weight of about 1000, a flowing point of -3 C, a boiling point of 150 (.5 kpa), a viscosity of 325 mpa. s, a refractive index of 1.472 (25 C), a solubility of less than 0.01% (25 C) in water, a solubility of 0.55% (25 C) in water, an organic solvent such as hydrocarbons, ketones, esters and *** alcohols, and slightly soluble in ethanol. This product is the most widely used non-toxic plasticizer and stabilizer of polyvinyl chloride. It has good compatibility with PVC resin, low volatility and small migration. It has excellent thermal and light stability, water resistance and oil resistance. It can give good mechanical strength, weatherability and electrical properties, and is non-toxic. It is an internationally recognized chemical additive for food packaging materials. This product can be used in all PVC products. Such as all kinds of food packaging materials, medical products, all kinds of films, sheets, pipes, refrigerator seals, artificial leather, floor leather, plastic wallpaper, wire and cable materials and other daily plastic products, can also be used in *** ink, paint, paint, synthetic rubber and liquid composite stabilizers.

Usage and dosage: This product can reduce the migration of polyester plasticizer when used with polyester plasticizer. It has remarkable synergistic effect with metal thermal stabilizer. The stabilization effect can be limited by *** and the amount of metal soap can be reduced to one third of the total amount required for the original use alone. Because the compatibility of this product with PVC is similar to that of DOP. And its plasticizing efficiency is better than DOP, and the use of this product can reduce the amount of total plasticizer in products. This not only reduces the cost, but also improves the technical specifications of the product, such as impact strength, transparency, printability, weldability and so on. Using 5 to 10 copies of this product in general soft products can obviously improve its thermal and light stability. Under special conditions, 10-30 phr can be added without other stabilizers under non-open-air conditions. The use of this product can appropriately reduce the amount of other plasticizers, stabilizers and lubricants.
Storage: Under normal storage conditions, it can be kept for more than two years.
Packaging: 200 kg net metal barrel.
