A new environmentally friendly non-toxic calcium-zinc compound stabilizer has recently been successfully developed and put on the market in Shandong Novista Chemicals Co., Ltd.
At present, lead-salts and metal soaps are used as stabilizers in the production of PVC products in China. Due to the large amount of lead salts used in the formulation, environmental pollution, high plasticizing temperature, poor fluidity, and discoloration in case of sulfur are caused. With the increasing environmental protection requirements for plastic products, the development of environmentally friendly non-toxic PVC compound stabilizers has attracted more and more attention.
Since 2014, Shandong Novista Chemicals has invested more than 15 million yuan to carry out technical research with the strong support of scientific research institutions. It has successfully developed environmentally friendly calcium-zinc-free PVC compound stabilizers. The product has the characteristics of non-toxic and odorless, good plasticizing performance, and smoothness of the product. Its metal content is greater than or equal to 8%, its initial melting point is greater than or equal to 95°C, and its technical indicators have reached the foreign product standards. At present, this product has been used in Shandong, Tianjin, Zhejiang and other places of food packaging materials and profiles, pipe, plate manufacturers, products in addition to selling at home and abroad, but also exported to the United States, Europe and other markets.
