For a long time, polyurethane environmentally friendly plasticizers have been mainly o-benzene products. However, as DOP is more and more widely used in the food and pharmaceutical industries, people are becoming more and more toxic to it. Pay more attention to it. Someone found that when people transfused blood stored in polyvinyl chloride plastic bags, DOP products were found in the human body, especially in the lungs.
Plasticizer is one of the plastic additives with the largest production and consumption in the world. my country has become the country with the largest plasticizer production and consumption in Asia. With the improvement of environmental awareness in various countries around the world, plastic products such as pharmaceutical and food packaging, daily necessities, toys, etc. have put forward higher purity and hygiene requirements for the main plasticizer DOP. However, the main plasticizers currently produced by domestic enterprises cannot meet the requirements of environmental protection in many aspects, especially hygiene and low toxicity.
Companies should increase research and development efforts, develop new plasticizer varieties, bypass technical barriers, and re-occupy the international market. The world’s development of environmentally friendly plasticizers obviously lags behind the needs of production and life. With the advancement of science and technology, some traditional materials may be eliminated, and new environmentally friendly plasticizers that are harmless, cheap, and effective as additives are developed. Plastics, as alternative materials, are a key part of the development of the current plastic products industry.
The main types of epoxy plasticizers are: epoxy soybean oil, epoxy acetyl linoleate methyl ester, epoxy butyl furfurate, Oxygen butyl oleate, epoxy octyl soybean oleate, 9,10-epoxy octyl stearate, etc. In PVC products, it is mainly used for its characteristics of both plasticity and stability. Epoxy plasticizer (epoxidized grease) is a type of excellent polyurethane environmentally friendly plasticizer produced by the epoxidation reaction of natural grease with organic peroxyacid. It has minimal toxicity and is compatible with the main plasticizers DOP and DBP. In comparison, its outstanding advantages are non-toxic, heat resistance and light stability, and it is allowed to be used as packaging materials for food and medicine in many countries.
