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.”

Sailun Group, a prominent player in the global tyre industry, has taken a leading role in advancing sustainable natural rubber practices. As a core raw material for tyre manufacturing, natural rubber requires ecological protection and a stable supply, both essential for the sector’s high-quality development. In 2025, the company, as a member of the Global Platform for Sustainable Natural Rubber (GPSNR), initiated a project focused on sustainable livelihoods and ecological education for smallholders in eastern Thailand under the GPSNR Shared Investment Mechanism.

This initiative unites strategic partners across the natural rubber value chain, including the Rubber Authority of Thailand’s Rayong office and Save the Children Thailand. Through multi-stakeholder collaboration, the project aims to foster a more sustainable natural rubber ecosystem. Recently, Sailun Group invited GPSNR Chief Executive Officer Stefano Savi and his delegation to Thailand for a field visit to review the project’s interim achievements, reflecting the company’s ‘eco+’ sustainability strategy and its active role in global governance for sustainable natural rubber.

Eastern Thailand’s natural rubber industry supports millions of smallholder households, and the project directly addresses the needs of 500 such farmers. Targeted training programmes have been delivered on environmentally responsible tapping techniques and regulatory compliance, including guidance on the European Union Deforestation Regulation. An innovative consultation network comprising one central hub, eight fixed stations and five mobile units now provides ongoing support on policy interpretation and practical problem-solving.

A structured and replicable knowledge system has been developed, including training materials on low-impact tapping and compliance. Special emphasis is placed on encouraging women and young people to participate, promoting intergenerational knowledge transfer. During the visit, the delegation held technical discussions with Rayong officials on sustainable tapping and rubber tree management, inspected standardised production lines and logistics facilities and reviewed the consultation stations, praising the integrated technology, services and compliance support model.

To address challenges such as improper tapping and soil degradation, five GPSNR demonstration plots have been established. Smallholders receive free organic soil improvement packages and professional tapping tools, alongside systematic training on sustainable soil management. The delegation observed pH monitoring systems and noted improvements including reduced soil acidity and better growing conditions. Direct engagement with farmers provided insights into practical challenges, and the delegation commended the project’s pragmatic approach to strengthening ecological cultivation and long-term productivity.

Beyond livelihood improvements, the project prioritises education through infrastructure upgrades at three schools attended by rubber farmers’ children. In partnership with Save the Children Thailand, ecological education corners with tailored curricula and drawing competitions have been set up. A scholarship programme supports disadvantaged students. The delegation visited Rayong Guanghua School and Banraijandee School, reviewing improvements and awarding scholarships, while discussions explored future collaboration on integrating sustainable natural rubber development with children’s ecological education.

Since implementation began, notable interim results have been achieved across multiple rubber‑producing communities. Smallholders’ sustainable production capabilities have significantly improved, while more children engage with nature and understand the natural rubber industry. This dual‑impact model of economic empowerment and environmental stewardship guides future efforts. Sailun Group will continue leveraging its industry leadership and the GPSNR platform to deepen collaboration with partners, research institutions and non‑profits, contributing to biodiversity conservation, supply chain resilience and high‑quality sustainable development across the global tyre and natural rubber industries.

Shin-Etsu Chemical has announced a sweeping price revision for its entire range of silicone products, effective for all shipments from 1 May 2026. The adjustment applies to every product handled by the company’s Silicone Division, with increases set at a minimum of 10 percent. Actual revision rates will vary depending on the specific product category.

The decision follows recent developments in the Middle East, which have triggered sharp surges in crude oil and naphtha prices. This has led to a steep rise in the cost of oil-derived raw materials. Additionally, Shin-Etsu Chemical is confronting higher expenses related to manufacturing energy, product containers, packaging materials and logistics, all of which have contributed to the need for a price correction.

Despite exhausting all possible internal measures to reduce manufacturing costs, the company concluded that these efforts alone cannot absorb the mounting cost pressures. Shin-Etsu Chemical is now committed to fully communicating the situation to its product users and securing their understanding of the necessary selling price revisions.
