Continental Becomes First Tire Manufacturer to Use LANXESS's Sustainable Rubber Additive

Continental has become the first tire manufacturer to implement LANXESS's new Vulkanox HS Scopeblue rubber additive in its production processes, marking a significant step toward sustainable tire manufacturing. 

The new additive represents a more sustainable version of the proven Vulkanox HS (TMQ) compound, carrying ISCC PLUS certification. LANXESS achieves the reduced environmental impact by incorporating bio-circular acetone and renewable energy sources during production, while maintaining the same chemical structure as the conventional product.

"At Continental Tires, we are continuously working to improve the environmental performance of our products," said Steffen Ryssel, Head of Purchasing at Continental Tires. The company aims to use over 40 percent renewable and recycled materials in its tires by 2030.

The sustainable additive delivers more than 30 percent lower CO2 footprint compared to conventionally manufactured alternatives. Despite the environmental improvements, tire manufacturers can integrate the product without modifying existing production processes, as the overall chemical structure remains unchanged.

Vulkanox HS Scopeblue serves as a protective agent for rubber compounds during vulcanization, shielding materials from oxygen and heat exposure. The additive enhances thermal stability during early processing stages and ensures long-term tire performance. Additional benefits include low volatility and reduced migration tendency.

Dr. Jens-Hendrik Fischer, Head of LANXESS' Rhein Chemie business unit, expressed satisfaction with Continental's adoption of the product. "We are delighted that Continental, a premium manufacturer, has chosen our Vulkanox HS Scopeblue for its products," he stated.

LANXESS developed the additive under its Scopeblue label, which identifies products with particularly low carbon footprints or high proportions of circular raw materials. Production occurs at an ISCC PLUS-certified facility in Germany using mass balance methodology.

The company calculates carbon footprint using the cradle-to-gate approach, encompassing direct emissions (Scope 1), indirect energy emissions (Scope 2), and other indirect emissions (Scope 3).

LANXESS, a leading specialty chemicals company, reported EUR 6.4 billion in sales for 2024 and employs approximately 12,000 people across 32 countries. The company has achieved recognition in sustainability indexes including the Dow Jones Best-in-Class Index and MSCI ESG ratings.
