Changhe Tianze: Injecting Fresh Momentum into the Rubber Industry

Shanxi Changhe Tianze Synthetic Material Manufacturing Co., Ltd. was founded on December 28, 2021, located in the south side of Xiuyi Street, Xiahe Industrial Park, Jinzhong Development Zone, Shanxi Demonstration Zone, Jinzhong City, with a registered capital of RMB 10 million.

The company holds the national high-tech enterprise certification and has passed ISO9001, ISO14001 and ISO45001 system certification. Its tire filler products comply with EU RoHS, REACH and German PAHS testing standards.

Its core business covers mineral fillers for tires and rubber products, Changhe carbon black, recycled rubber, and C series compound fillers dedicated to NR, NBR and EPDM rubber sealing applications. These products significantly enhance the performance of rubber products, and the company maintains in-depth cooperation with well-known tire and rubber companies at home and abroad.

The company maintains industry-academia-research cooperation with the School of Polymer Materials of Taiyuan University of Technology and employs Prof. He Hongwei as a consultant. This cooperation has achieved remarkable results in the research and development of related products, and a number of projects are under field testing, showing broad market prospects.

Changhe Tianze Carbon Black: Where Green and Performance Converge

Shanxi Changhe Tianze focuses on the core needs of the rubber industry and develops a diverse portfolio of high quality products. The core products cover three categories:

1. Specialized mineral fillers for tires and rubber products;

2. Changhe Carbon Black and Reclaimed Rubber, utilizing waste tire recycling technology to achieve a combination of environmental sustainability and practicality;

3. C-01 to C-08 series compound fillers, customized for a wide range of applications in natural rubber (NR), nitrile butadiene rubber (NBR), ethylene propylene diene monomer (EPDM), and other rubber products.

All products are rigorously tested. Tire fillers are compliant with EU RoHS, REACH and German PAHs standards and significantly improve air tightness, surface gloss, heat dissipation and reduce specific gravity of rubber products. Widely used in tire manufacturing and sealing production, we provide stable and reliable material support for domestic and foreign partners.

Renewed vitality from waste tyres, Green carbon black's fresh value

The TZN550A eco-friendly carbon black series, co-developed by our company and Taiyuan University of Technology for sealing component market demands, replaces traditional N550 carbon black. It delivers over 95% of conventional carbon black’s performance at only 80% of traditional N550’s cost.

Mineral filler is mainly manufactured from coal through purification and modification process. It is widely used in various natural and synthetic rubbers as filler, bulking agent and reinforcing agent, mainly in industrial rubber products such as tire innerliners and sidewalls.

High-precision design utilises advanced moulding technology to ensure dimensional accuracy and consistency.Offers multiple materials including nitrile rubber (NBR), fluorocarbon rubber (FKM), and silicone rubber (VMQ) to suit varied operating conditions.

The product portfolio spans multiple rubber industry applications, precisely meeting the performance requirements of diverse sectors.

Mineral fillers, Changhe carbon black and recycled rubber enhance tyre airtightness, improve heat dissipation and structural stability. Suitable for passenger car, commercial vehicle and other tyre production, they contribute to reduced tyre weight and increased durability.

C-01/C-02/C-03/C-08 series composite fillers, customised for NR, NBR, EPDM and other rubber sealing materials. Widely applied in automotive seals, mechanical seals, pipeline seals and similar scenarios, enhancing weather resistance and sealing efficacy.

Reclaimed rubber and carbon black products, suitable for manufacturing rubber hoses, conveyor belts, and vibration dampers. Balancing cost and performance, they meet industrial transmission and equipment vibration reduction requirements.
