Arlanxeo, a world-leading synthetic rubber company, recently launched its Keltan Ultra-High Mooney 100+ Innovation Platform. Based on the novel Keltan ACE catalyst technology and the excellent finishing process, this platform is primarily focused around the development of new grades with high Mooney viscosity, to optimize physical properties and cost, thus to satisfy the demand for the upgrade of applications across industries, including automotive, construction, and transportation.

Currently, markets are calling for better EPDM products. A major challenge in this has been finding the balance between improved physical properties and reasonable production costs. To satisfy the tight requirements from domestic clients, Keltan Ultra-High Mooney 100+ Innovation Platform has launched three new grades – Keltan 13561C, Keltan 10660C, and Keltan 10950C. Each of these grades has adopted Keltan Controlled Long Chain Branching (CLCB) technology, achieving good mechanical and processing performance. Meanwhile, this platform is about to launch a new Ultra-High Mooney oil-extended grade – Keltan 10675C (50 phr of extender oil).

Keltan 13561C has Mooney viscosity of 130MU at 125℃. Its ultra-high molecular weight enables higher mechanical property that is the same as or even higher than crystalline grades, but without issues of inferior low-temperature performance, high shrinkage, etc. Keltan 10660C reaches 100MU at 125 ℃ and possesses both ultra-high molecular weight and a combination of processing and mechanical properties. With this, Keltan 10660C can be applied to general mixing devices. Both grades are able to bring reduced costs through increasing compound loading without influencing the mechanical property. By virtue of the advantages of ultra-high Mooney, non-crystalline, fast vulcanization, higher elasticity and compound loading, Keltan 13561C and Keltan 10660C can adapt to strict standards of production and application and are widely applied to produce automotive seals and hoses, seals for construction, and rubber products for rail systems.

Sponge grade Keltan 10950C reaches Mooney viscosity of 100MU at 125 ℃. Due to the high Mooney viscosity, the grade also enables a reduced cost with increased compound loading while still maintaining the same mechanical property and compression set. Compared with the previous sponge grades, Keltan 10950C has a larger molecular weight, higher elasticity and non-vulcanized compound strength, and excellent extrusion performance, like outstanding flowability, better collapse resistance, and good profile appearance, offering an alternative for producing high-performance sponge seals. Major applications of the grade include auto sponge profiles, window sponge profiles, and insulation materials for construction.

 “Arlanxeo Keltan Ultra-High Mooney 100+ Innovation Platform is committed to fulfilling the customers’ demand for products with higher performance and lower cost. Facing the new challenges and opportunities ushered by the industrial upgrades, we will stay innovative, close to the local market, and customer-centric, and continually innovate to provide excellent products and services”, said Dr. Baojia Cheng, Head of TSAD and R&D, HPE Asia, ARLANXEO.

The three Keltan grades above are all produced by Arlanxeo Changzhou plant and are available in the market.

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 Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly NR Statistical Report for October 2025, providing an overview of key developments in the global natural rubber sector.

According to the report, the global natural rubber market in October was characterised by a distinct bearish trend in pricing. This decline can primarily due to a significant surge in production and export activities, which were initially stimulated by the higher prices seen earlier in the year. Meanwhile, overall demand has remained relatively subdued.

Looking ahead to the full year, projections indicate a modest 1.3 percent increase in global production for 2025, a figure that follows a recent downward revision for Indonesia. On the demand side, consumption is anticipated to grow by a slight 0.8 percent, influenced by an upward adjustment to Indonesia's consumption data. Despite the current price pressures, market sentiment shows some mixed signs of improvement, particularly within the tyre trade of certain specific markets.
