Zhong Guo Hua Gong Bao·2026-02-09 03:03Group 1 - The 2025 Shandong Province Top Ten Technological Innovation Achievements were announced, featuring high-performance citral developed by Wanhua Chemical Group and high-end tire barrier materials led by Shandong Daon Polymer Materials Co., Ltd [2][3] - Citral is a high-value fine chemical used as a key raw material in synthetic fragrances and nutritional chemicals, with applications in daily chemicals, feed, food, and pharmaceuticals. Wanhua Chemical has developed a production technology that breaks the foreign monopoly, achieving a purity greater than 99%, which is 2 percentage points higher than similar foreign products [2] - The global largest single-set industrial citral production facility has been established, which does not generate solid waste and employs inherently safe design for greener manufacturing. The product has generated sales revenue of 500 million yuan and is expected to reach an annual output of 40,000 tons and an annual output value of 2 billion yuan in three years [2] - The high-end tire barrier material developed by Shandong Daon, in collaboration with Beijing University of Chemical Technology and Linglong Tire, has achieved breakthrough technology in cross-linked dynamic vulcanization and composite membrane preparation, becoming the second company globally to master this technology [3] - This material has a gas barrier performance 7 to 10 times better than traditional vulcanized butyl rubber, allowing a weight reduction of about 1 kilogram per tire and a 5% increase in vehicle range. It is expected to generate an annual output value of 1 billion yuan within two years, driving nearly 10 billion yuan in upstream and downstream output [3] Group 2 - The selection of the 2025 Shandong Province Top Ten Technological Innovation Achievements was conducted by over 60 academicians and experts from within and outside the province, representing the latest achievements and highest levels of technological innovation in Shandong [3]
