China Drying Newsletter “After the excessive incident of plasticizers in alcoholic drinks, domestic plastic hose manufacturers have contacted us to prepare to use our new benzene-free plasticizers for the production of liquor conveying pipes. According to these customers, All of the environmental protection products they produce are exported. If they are not affected by the impact of plasticizers, their domestic orders will not come so quickly.†On December 3, Yan Jianqiang, Chairman of Shandong Wantu Polymer Materials Co., Ltd. stated that .
According to Yan Jianqiang, in 2010, Shandong Wantu cooperated with the State Key Laboratory of Polymer Materials Engineering of Sichuan University and began research and development of environmentally friendly and safe plasticizer products. After more than a year of scientific research, a new type of plasticizer (WT98) came out; this year, Wantu began mass production of WT98 plasticizer with an annual production capacity of 20,000 tons.
It is reported that the company has successfully developed a series of safety plasticizers such as WT98, WT99 and WT108. The performance of the products has reached the international advanced level and passed the inspections of international authoritative testing organizations such as SGS, RoHS and REACH. Phthalates and heavy metals, which can completely replace conventional plasticizers such as dioctyl phthalate (DOP) and dibutyl phthalate (DBP), comply with EU 2005/84/CE environmental requirements and are applicable to Medical infusion tubes, blood transfusion bags, food grade hoses, winery-specific tubes, children's toys, food packaging, and many other applications that require high environmental performance.
Prof. Lei Jingxin, professor of Sichuan University and technical consultant of Wantu Company, said that currently, there are three types of plasticizers in the market, o-benzene, benzene and citric acid esters. The former two categories all contain benzene, and long-term exposure will have a serious impact on health. The citric ester plasticizers, although not benzene, have high volatility, environmental pollution during processing, and are not suitable for use due to their very bitter taste. Medical products, children's toys, food packaging and other fields; there is also a kind of cyclohexane, which is obtained through the hydrogenation of benzene ring and still has low toxicity to the human body. The new plasticizer developed by Shandong Wantu is based on plant extracts as raw materials, environmental protection non-toxic, colorless and bitter.
After the new benzeneless plasticizer produced by Wantu of Shandong Province was listed on the international market, the Brazilian Plastics Industry Association had a keen interest in it and had sent a special trip to the company for inspection and expressed a strong cooperation intention. At the same time, some domestic exporters of medical devices, foods, medicines, toys, etc. have begun to become Wantu's customers in order to meet the standards of developed countries such as Europe and the United States.
