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.”

The German Rubber Industry Association (wdk) has sounded an alarm over an exceptionally difficult economic situation facing the rubber sector. Soaring raw material prices and persistently high energy costs, exacerbated by the Iran war, are coinciding with weak industrial demand. wdk Chief economist Michael Berthel noted an almost unprecedented economic disparity, as raw material costs approach historical highs from 2011 and 2022 while a lack of demand prevents any offset for manufacturers.

Since the final quarter of 2025, prices for key inputs have risen sharply. Natural rubber has jumped more than 40 percent within months, while butadiene-based synthetic rubbers have increased over 30 percent. EPDM synthetic rubber, carbon black and oil-based plasticisers have all risen more than 20 percent, with some individual chemicals exceeding 40 percent cost growth in just a few weeks.

Energy prices remain a major burden, with Middle East developments fuelling market uncertainty. Risks to international transport and supply chains persist, and German rubber companies are closely watching potential impacts on raw material availability and global logistics flows.

Berthel warned that firms face mounting pressure from high costs, geopolitical instability and structural disadvantages in Germany, with no short-term relief in sight. The industry depends heavily on fair and reliable partnerships across the value chain, as processing companies alone cannot absorb the current strain. He called for fair solutions and a shared understanding of this exceptional situation.

The Rubber Board of India has confirmed the continuation of all existing central sector schemes for the 2026-27 fiscal year at unchanged rates. Financial aid for new planting will be restricted to estates utilising poly bag or root trainer plants sourced solely from Board-approved nurseries, with applicants required to submit the original purchase bill. This mandatory verification step aims to ensure quality and authenticity of planting materials used across the sector.

Support for rain guarding and spraying operations will be channelled exclusively through Rubber Producers’ Societies. These societies must include GST bills for all acquired materials when applying. The official timeline for submitting applications will be announced separately by the Board, giving producers adequate time to prepare documentation and coordinate with their respective societies before the deadline.

Bekaert has officially finalised its acquisition of Bridgestone’s tyre reinforcement operations in China and Thailand, after securing all necessary regulatory approvals and meeting standard closing conditions. The deal, now fully completed, marks a significant step in the Belgian company’s expansion strategy.

The transaction brings under Bekaert’s control two production facilities: Bridgestone (Shenyang) Steel Cord Co., Ltd. in China and Bridgestone Metalfa (Thailand) Co., Ltd. in Thailand. These plants specialise in manufacturing high-quality tyre cord products exclusively for Bridgestone tyres, and they will continue to supply Bridgestone under the new ownership, further deepening the longstanding partnership between the two firms.

Financially, the acquisition is expected to add roughly EUR 80 million to Bekaert’s annual consolidated sales. The EUR 60 million cash consideration for the deal was funded from the company’s available cash reserves.

Curd Vandekerckhove, CEO Rubber Reinforcement, said, “With the completion of this acquisition within our Rubber Reinforcement division, we are pleased to officially welcome the plant teams in China and Thailand to Bekaert. Our immediate focus is on a smooth transition and operational continuity while continuing to serve Bridgestone as a key strategic partner. The completion of the acquisition further strengthens the position of Bekaert in the tyre cord market, expands the global manufacturing footprint and deepens our longstanding partnership with Bridgestone. A long-term supply agreement ensures continued delivery of high-quality tyre reinforcement within a trusted supplier model.”
