Zhejiang Shunda New Material Co., Ltd. disclosed that the food-grade polyisobutylene (PIB) product produced by the company's own research and development of 6,000 tons/year with boron trifluoride as the catalyst obtained the sanitation license of Zhejiang food additive production enterprise. Products are approved for mass market launch. The company has thus become China's first producer of food-grade polyisobutylene using boron-based technology, breaking the monopoly of the domestic food-grade polyisobutylene market that is completely monopolized by imported products, with product prices 30% to 40% lower than imported products.

It is understood that with the help of the national polyisobutylene experimental center of Zhejiang University, through long-term technical breakthroughs, the company built the first food grade polyisobutylene pilot plant in 2007. After continuous improvement, its technology has matured. Obtained a series of invention patents.

In February 2010, the company invested 100 million yuan to build the first domestic food-grade polyisobutylene project using boron-based technology. The designed capacity was 6,000 tons/year, and it was completed in June 2011, making the company a successor to the company. After BASF, the world’s second company to master the production of polyisobutylene using boron trifluoride as a catalyst system. Its product quality is stable and reliable, all aspects of the indicators have reached the world's advanced level, the product has a narrow molecular weight distribution, solvent residue is small, and compared with similar products, prices fell by 30% to 40%.

According to reports, due to high technical barriers, there are currently only three companies in the world that can professionally produce food-grade polyisobutylene, namely BASF, Zhejiang Shunda and Japan's Shinrishi Corporation. Shunda's current production capacity ranks second in the world. . The industrial grade polyisobutylene industrialization project developed in cooperation with the National Laboratory of Polymerization Reaction Engineering of Zhejiang University was once included in the National Torch Plan, but the product was upgraded from the industrial level to the food grade, replacing imported products to break the international monopoly, from the technology It is a great leap forward and is also the goal pursued by the company over the years.

Polyisobutylene is polymerized from isobutylene. This reporter learned that food grade polyisobutylene can be widely used in chewing gum, gum and food packaging and other fields. In recent years, the market demand for global food grade polyisobutylene has been increasing at a rate of more than 15% every year, and the market prospect is very broad. However, due to technical constraints, the domestic food grade polyisobutylene market has long been monopolized by BASF and Japan's Shin-Rishi Corporation.
