Innovating Tire Manufacturing: Changfu Chemical’s Mercapto-Silane Oligomer Boosts Rubber Performance Upgrade

In tire rubber production, the use of silane coupling agents (like KH-590) leads to the release of alcohols. Improper process control may harm rubber denseness and long-term stability. Balancing material performance and process reliability remains an industry focus.

Changfu Chemical’s Solution: The Innovative Value of Mercapto-Silane Oligomers

With years of R&D experience in silane materials, Changfu Chemical has launched a new series of mercapto-silane oligomers to offer better options for rubber composite materials:

Low volatility: By optimizing the molecular structure, it significantly reduces the generation of volatile substances during hydrolysis, improving the internal uniformity of rubber;

Enhanced interfacial bonding: The unique mercapto functional group design promotes chemical bonding between fillers and the rubber matrix. Lab tests show it can enhance the mechanical properties of composites;

Process-friendly: It can achieve efficient coupling reactions at mild temperatures, potentially optimizing production energy consumption.

Lab Data (based on typical formula tests)

- A clear downward trend in bubble defect rate compared with traditional processes

-Significant improvement in dynamic heat generation and rolling resistance indicators

- Potential for improvement in vulcanization efficiency and cost control

Changfu Chemical’s mercapto-silane oligomers meet strict industry environmental standards, with much lower volatile organic compound (VOC) emissions than traditional silane products, helping companies meet the needs of upgrading environmental regulations.

Customer - oriented, Changfu Chemical offers customized technical solutions and full-process support. We look forward to working with global partners to promote the efficient and eco-friendly development of rubber materials.
