Serving the nationwide rubber materials market while expanding global operations

Technical R&D Advantages

Through a corporate partnership with the College of Polymer Materials of Taiyuan University of Science and Technology, Prof. Hongwei He has been appointed as a technical advisor. This cooperation focuses on breakthroughs in two core technology directions: first, the development of mineral fillers using Shanxi coal as a raw material; and second, deepening expertise in waste tire recycling to develop recycled carbon black and high-viscosity, high-elasticity asphalt technologies. At the same time, we customize C series composite fillers for sealing applications to ensure that the technical achievements are precisely aligned with the market demand, while continuously strengthening the product performance barriers.

Product Competitive Edge

Our products offer both “high performance” and “excellent price/performance ratio”: for example, the environmentally friendly TZN550A carbon black replaces the traditional N550 and achieves 95% of the performance at 80% of the cost; and the related products are compliant with EU RoHS, REACH and German PAHS tests, REACH and German PAHS tests, including mineral fillers, recycled carbon blacks and seal-specific composite fillers. This versatility simultaneously meets the requirements of tire manufacturing, seal production and road construction, ensuring strong adaptability.
