Recently, in order to meet the EU's export certification requirements, more and more plasticizers users begin to look for methyl chloride, bio-ester plasticizer.  It can be seen that the development trend of plasticizer is increasingly turning to environmental protection, health, safety. 

Biological plasticizer (epoxy fatty acid methyl ester) is a waste oil (soy acid) production of epoxy plasticizer, characterized in that: the use of waste oil (soybean acidification oil) as raw material, after pretreatment, the resulting glycerol, under the alkali catalysis, with methanol ester exchange reaction, to obtain fatty acid methyl ester, and then with the reaction products of hydrogen peroxide and organic acid-peracetic acid, the direct epoxidation reaction, the epoxy fatty acid methyl ester coarse products, and then washed acid, distillation dehydration to get epoxy fatty acid methyl ester finished products. 

Compared with epoxy vegetable oil plasticizer, epoxy fatty acid methyl ester plasticizer can not only completely or partially replace DOP plasticizer to create a non-toxic, environmentally friendly PVC products for food packaging, medical supplies materials, toys and water supply pipeline, but also used as cellulose resin and synthetic rubber non-toxic plasticizer and softener, in the processing of products, the addition of epoxy fatty acid methyl ester can significantly improve the physical properties of the product and prolong the aging time, and with the use of barium, cadmium, zinc and other metal stabilizers, has a good synergistic effect.  

In addition, because of its good lubricity, compatibility and dispersibility, it can also be used as a surfactant and dispersant for epoxy coatings and epoxy resin production industries, but because of its low temperature crystallization (curing is not complete, migration) and other problems, limiting its application in epoxy resin. 

As the whole PVC industry in recent years, the market downturn, profit is thin, many enterprises are in the pursuit of lower costs, while the price of the plasticizer at the source of petroleum products is still at a high level, so the price of raw materials from the low-priced plasticizer (which is represented by epoxy fatty acid methyl ester), have been identified as having good market prospects.
