Epoxidized soya bean oil(esbo) is a chemical product produced by oxidation of soybean Oil. It is a light yellow viscous oily liquid at room temperature. It is a widely used non-toxic plasticizer and stabilizer of PVC.It has excellent thermal stability and light stability, water resistance and oil resistance, and can give products good mechanical strength, weather resistance and electrical properties, and is non-toxic. It is an internationally recognized chemical process additive for food packaging materials.
Epoxidized soybean oil is a pale yellow viscous viscous oil-like liquid at room temperature. Its solubility in water is less than 0.01 (25℃), and its solubility in water is 0.55% (25°C). It is soluble in organic solvents such as hydrocarbons, ketones, esters and higher alcohols, and slightly soluble in ethanol.The product is one of the most widely used PVC non-toxic plasticizer and stabilizer: good compatibility with PVC resin, low volatility, small mobility.It has excellent thermal stability and light stability, water resistance and oil resistance, and can give products good mechanical strength, weather resistance and electrical properties, and is non-toxic. It is an internationally recognized chemical process additive for food packaging materials.It can be used in all PVC products.Such as all kinds of food packaging materials, medical products, various films, sheets, tubes, refrigerator seals, artificial leather, floor leather, plastic wallpaper, wires and cables and other daily plastic products, can also be used for special inks, paints, coatings, synthetic rubber and liquid composite stabilizer.
In general, the higher the ESO epoxy value, the better the heat resistance, the lower the price of ESO iodine and the better the compatibility with PVC, the less easy to precipitate!
Epoxidized Soybean Oil
Epoxidized soybean oil manufacturers will introduce its characteristics.
Comply with FDA food additive regulations "181.27 and 175.300".It has been approved by JHPA PL specification [b.7 (1)] (approved number: j-7059).Especially suitable for food packaging or medical materials.
(2) low volatility, resistance to extraction and resistance to migration
The molecular weight of b-22 and b-22d is about 1000, and its volatility is 1/5 of that of DOP, and its solvent resistance is much better than that of DOP.The iodine price of b-22 and b-22d is low, so the migration resistance is good.
(3) excellent weather resistance and heat resistance
B-22 is used together with metal stabilizer in PVC products. Synergitism can improve the weather resistance, heat resistance and transparency of PVC resin, and reduce the amount of metal stabilizer and reduce the cost.
In today's environmental awareness, b-22 and ca-zn stabilizers are pollution-free and non-toxic formulations that can replace cd-ba-zn or lead stabilizers.In the refractory formula, b-22 was added, and the stability was greatly improved.
