Flexsys Develops First Viable Industry Alternative to 6PPD in Major Breakthrough for Tyre Chemistry

- December 02, 2025
Flexsys has created what it says is the tyre industry’s first practical and scalable alternative to 6PPD, marking a major step toward replacing a chemical used for decades but now under regulatory pressure.
The company said the new antidegradant is the result of several years of research and testing with federal laboratories, independent scientific groups and tyre makers. Early results show the material could match the performance and safety of 6PPD while avoiding the environmental risks linked to 6PPD-quinone, a transformation product identified in 2020.
Flexsys said the new chemistry provides the short- and long-term protection needed to stop tyres cracking or ageing. It is also designed to fit into existing rubber compounds with minimal changes, which could help manufacturers adopt it quickly. The company added that the product meets environmental and regulatory benchmarks, including criteria set by the Washington State Department of Ecology.
Importantly, the new molecule is not part of the “PPD” family, meaning it does not form quinone during use. Flexsys said this would remove the environmental impact associated with 6PPD-quinone. The company is also using many of the same intermediate chemicals already used in 6PPD production. This could allow manufacturers to rely on existing factory assets and speed the shift to the new technology.
“This achievement reflects our unwavering commitment to responsible innovation, built on decades of expertise in tire protection chemistry,” said Carl Brech, Chief Executive Officer of Flexsys. “Our solution is formulated to deliver the performance and reliability that tire makers expect and is designed for future environmental and regulatory standards.”
6PPD has been essential to tyre durability for 50 years. But studies published in 2020 showed that 6PPD-quinone could harm aquatic species, including coho salmon. Regulators and tyre producers have been looking for a safer option since then. Flexsys said its new antidegradant meets this challenge without reducing tyre safety.
“Our team set out to develop a next-generation antidegradant that meets the tire industry’s highest performance standards without compromising tire safety, while also reducing toxicity,” said Neil Smith, Chief Technology and Sustainability Officer. “I could not be more proud of the perseverance and dedication of the Flexsys R&D team. Our group has been highly motivated by both the technical challenges of this project as well as the positive societal impact that this work will ultimately have.”
Flexsys acknowledged support from the Sustainable Polymers Tech Hub in Akron, Ohio, part of the U.S. EDA Tech Hubs programme.
The company is now working on process optimisation to allow large-scale production. It is also in discussions with regulators around the world to secure approvals for commercial use. Testing with tyre makers is continuing.
“Flexsys is helping set the direction of the tire industry for the coming decades with this development,” Brech said. “We will continue to work tirelessly to bring this breakthrough to the market as soon as possible.”

Yokohama Rubber And RAOT Hold 10th Joint Seminar For Thai Natural Rubber Farmers

The Yokohama Rubber Co., Ltd. recently conducted an educational seminar for local natural rubber farmers in partnership with the Surat Thani branch of the Rubber Authority of Thailand (RAOT). This marked the 10th such event since the programme's inception in 2020, involving 50 local farm households. Attendees received complimentary fertiliser, developed with RAOT's expertise, as part of the ongoing support.
The seminar curriculum covered essential agricultural topics, including soil and plant nutrition, correct fertiliser application and methods to prevent contamination in natural rubber. To commemorate the 10th seminar, the programme was expanded to include guest speakers from local government, police and healthcare. These guests addressed broader community and safety issues, such as human rights for foreign and minority workers, road safety and occupational health. A particular focus was placed on practical well-being, with the local hospital director offering guidance on preventing injuries during tree tapping and managing encounters with poisonous insects.
Post-event feedback from participants was overwhelmingly positive. Many expressed that they gained new, systematic knowledge about cultivation practices, despite years of experience. Several noted that hearing directly from a rubber manufacturer reinforced the critical importance of purity in their product. Others found the health and safety advice immediately useful. The engaging delivery of the seminar was also highlighted, with one farmer mentioning a desire to recommend the valuable and enjoyable experience to peers.
This initiative is a direct implementation of a memorandum of understanding (MoU) signed between Yokohama Rubber and RAOT in January 2020. The MoU focuses on economic support for farmers and improving supply chain traceability, aligning with the company's Procurement Policy for Sustainable Natural Rubber. Hosted in the region where Yokohama’s Thai natural rubber processing subsidiary, Y.T. Rubber Co., Ltd. (YTRC), operates, the seminar exemplifies the policy's guideline to support small-scale farmers within the supply chain.
As a founding member of the Global Platform for Sustainable Natural Rubber (GPSNR), Yokohama Rubber is committed to advancing these principles. The company views such efforts as integral to creating shared value under its sustainability slogan, ‘Caring for the Future’, and contributes to broader United Nations Sustainable Development Goals through the promotion of sustainable raw material procurement.

In a significant event for India’s rubber sector, Minister for Ports, Co-operation & Devaswoms V N Vasavan inaugurated a ceremony for the transfer of innovative latex-based paint technology. This eco-friendly paint, a product derived from natural rubber, was developed by the Rubber Products Incubation Centre of the Rubber Research Institute of India. The technology was formally handed over to Kerala Paints Industries Private Ltd., with the Minister highlighting the event's historic nature for launching a sustainable product and stressing the importance of increasing domestic natural rubber consumption to improve grower returns.
Rubber Board Executive Director M Vasanthagesan outlined the centre's role in converting research into market-ready goods, reaffirming the Board's dedication to creating innovative, value-added rubber products. The gathering also heard remarks from several key figures, including Mahatma Gandhi University's K V Dayal, RRII Director Dr Debabrata Ray, RRII Senior Scientist Dr Shera Mathew and Kerala Paints' Managing Director Midhun P Pullumettel.

ANRPC Publishes Monthly NR Statistical Report For November 2025

- December 22, 2025
The Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly NR Statistical Report for November 2025, providing an overview of key developments in the global natural rubber sector.
While a modest rise in global production of 1.3 percent is anticipated for the year, this follows a revised, lower output forecast for Indonesia. Concurrently, worldwide demand is projected to grow by a more subdued 0.8 percent, bolstered by an upward adjustment in Indonesia's own consumption figures.

Recent price pressures have emerged due to this combination of uncertain supply, influenced by unpredictable weather patterns and generally muted demand. However, there are sporadic positive indicators, including noticeable recoveries within the tyre sector across some regional markets.
