Longxing Chemical Stock Co Ltd

Longxing Technology Group announced that certain models of its sustainable development series carbon black products have passed certification by a well-known large European tire manufacturer and entered bulk supply, with an initial order of nearly ten thousand tonnes. At the same time, the company has reached a sustainable green carbon black product development plan with other prominent large European tire makers, which is being accelerated. This sustainable carbon black is produced by partially or fully replacing coal tar and other raw materials with tire pyrolysis oil, offering better economic returns than traditional carbon black. The company initiated related technology research and development in 2024, obtained environmental impact assessment approval in December 2025, and stated that based on downstream demand, expansion plans are already under consideration and will be gradually advanced according to order conditions.
