环氧增塑剂（Epoxy plasticizer） Study on the application of epoxy plasticizer [8] Epoxy plasticizers are less toxic and have been allowed to be used in food and pharmaceutical packaging in many countries and are the only epoxy plasticizers approved by the U. S. Drug Administration for food packaging materials. PVC is commonly used as an auxiliary heat stabilizer. They are used in combination with heat stabilizers and have a high synergistic effect. They are suitable for soft, especially soft PVC products exposed to sunlight. They are not normally used in hard PVC products. Epoxy plasticizer is a kind of plasticizer with low toxicity. Also a detailed study for the carcinogenicity of Maxwell epoxy compounds, most of the research is epoxidized soybean oil, in foreign countries can be used for plastic products in contact with food, in many countries have been allowed for food and pharmaceutical packaging materials, and has the light stability, water resistance and the advantages of non-toxic, and has a good synergistic effect with metal soap, organic tin stabilizer. M.T.Benanibaa will be added to the epoxy sunflower oil containing different metal soap salts (Ba/Cd and Ca/Zn) in PVC, by measuring the thermal stability of the materials, found that the sunflower seed oil and metal soap salt has a good synergistic effect, can enhance the thermal stability of PVC materials, and analyzed the reason of the synergy: degradation the HCl absorption of sunflower oil and metal soap salt, the concentration of HCl decreased, while reducing the PVC removal rate of HCl, improves the thermal stability of PVC. Plasticizer adjacent benzene two formic acid ester, straight chain ester, epoxy, phosphate, its comprehensive performance, DOP is a good variety, can be used for a variety of PVC products in the formula of straight chain esters (such as DOS) is a hardy plasticizer commonly used in plastic sheeting, it good compatibility with PVC, generally not more than 8. In addition, from the processing
