Flexsys, a prominent entity in material science and advanced tyre additives, has announced two significant advancements in its quest to develop a substitute for the chemical 6PPD. The company is progressing towards a new era in tyre manufacturing, having identified two primary molecular candidates that will undergo extensive evaluation. This development follows a prior announcement in November 2025, where Flexsys revealed it had created the first viable alternative to the established antidegradant.

The two finalist molecules have successfully passed rigorous internal and external testing, meeting stringent safety, performance and environmental standards. Significantly, neither compound belongs to the PPD chemical family, and crucially, they do not produce a quinone transformation product during usage. With the initial screening phase complete, Flexsys is now concentrating on expanded testing for these candidates, with the ultimate goal of selecting a definitive replacement for 6PPD in tyre production.

In a parallel effort to ensure environmental safety, Flexsys has formalised a Cooperative Research and Development Agreement with the U.S. Geological Survey. This collaboration is designed to independently and thoroughly assess the potential effects of the two molecules on aquatic ecosystems. Building upon a previous CRADA with the U.S. Department of Agriculture, this new agreement with the USGS represents a critical phase in determining the complete aquatic toxicity profile. The research will employ novel testing methodologies that extend beyond standard chemical registration requirements.

Under the agreement, scientists from the USGS Western Fisheries Research Center, alongside other USGS divisions, will study the molecules and their breakdown products. The focus will be on the impact on Pacific salmon and other aquatic species, utilising innovative cell-line research to pioneer new testing methods. This approach aims to create alternative assessment tools applicable to a wide range of chemicals. The CRADA formalises and expands upon preliminary testing that had already commenced at the research centre.

Flexsys acknowledged the support from the Economic Development Administration’s Tech Hubs Program, as a member of the Akron Sustainable Polymers Tech Hub. Concurrently, the company is optimising the process chemistry for both candidates to facilitate efficient, large-scale production. Both molecules utilise intermediate chemistry similar to that used for 6PPD, allowing the industry to leverage existing manufacturing assets. This strategic approach is expected to promote faster adoption and reduce overall investment costs while Flexsys continues its engagement with global regulatory agencies for commercial approval.

Carl Brech, Chief Executive Officer, Flexsys, said, “The tyre industry has been waiting for two things: a molecule that actually works and independent proof that it is safe. As of today, both are in hand or in motion. With tyre and environmental safety testing underway, the focus has shifted from finding a potential replacement to thorough validation, regulatory approval, scale-up and industry adoption.”

Neil Smith, Chief Technology and Sustainability Officer, said, “This marks a significant milestone for our team, and we’re pleased to announce we’ve narrowed our efforts to two final molecules that continue to meet our strict targets for in-rubber performance, scalability, toxicity profile and environmental sustainability. The selected alternative must be reliable and safe, not only today but for decades to come. USGS expertise provides independent evaluation with a level of rigour we could not execute on our own. We are proud to help pioneer novel toxicity-testing methods and eager to see the results.”

Michael Schmidt, Center Director, U.S. Geological Survey Western Fisheries Research Center, said, “USGS has spent the past five years studying the effects of 6PPD on aquatic species and developing innovative methods to screen the safety of potential alternatives. For nearly a century, the Western Fisheries Research Center has provided objective science to support management of aquatic species across the Western United States.”

The Association of Natural Rubber Producing Countries (ANRPC) published its Monthly Natural Rubber Statistical Report for August 2026, noting firmer prices in several markets. Supply constraints, stable downstream demand and persistent geopolitical and macroeconomic uncertainty shaped the month. Renewed conflict and disruptions to major shipping routes added further pressure.

Physical prices for major grades moved in different directions. SMR-20 in Kuala Lumpur averaged USD 2.31 per kg, up 4.25 percent from July, while STR-20 in Bangkok rose 1.40 percent to USD 2.39 per kg. RSS-3 dropped 4.18 percent to USD 2.80 per kg, but RSS-4 in Kottayam gained 0.57 percent to USD 2.92 per kg. Latex-in-bulk fell 4.73 percent to USD 1.73 per kg. Brent crude averaged USD 91.08 per barrel, driven by concerns over possible restrictions on oil shipments through the Strait of Hormuz and wider Middle East instability, which raised energy supply risks and strengthened the oil market risk premium.

On trade, China's imports climbed 3.39 percent month-on-month, while India fell 10.18 percent and Malaysia dropped 8.24 percent; Viet Nam rose 5.08 percent. Exports advanced 5.63 percent in Viet Nam but declined in Thailand (-5.24 percent), Indonesia (-5.36 percent), Malaysia (-1.48 percent) and Cambodia (-1.88 percent).

Global production is projected to rise 0.6 percent to 15.039 million tons in 2026 from 14.952 million tonnes in 2025, after revisions to Thailand's 2025 output and updated 2026 estimates for Thailand, Malaysia and Indonesia. Weather, including erratic rainfall and drier Southeast Asian conditions, affected output. August 2026 production was estimated at 1.396 million tonnes, down 4.51 percent from 1.462 million tonnes a year earlier. Demand is forecast to grow 0.4 percent to 15.356 million tonnes in 2026 from 15.301 million tonnes, with the largest consumption gains expected in China, Malaysia and Cambodia. Prospects depend on vehicle sales, tyre production, shipping conditions and weather-related supply disruptions, while steady EV-linked demand supported modest growth led by China and India. The ringgit traded between RM4.02 per USD and RM4.09 per USD, and the baht between 32.68 and 33.34. The SHFE January 2027 contract averaged 18,109 CNY per tonne, up 7.78 percent month-on-month, while the SGX November 2026 contract averaged USD 2.24 per kg, up 4.32 percent.

Kumho Petrochemical Group is steering its business towards research-driven, higher-value outputs as oversupply and soft demand continue to weigh on the worldwide petrochemical sector. The Seoul-based group outlined plans to boost spending on speciality chemicals, sustainable materials and novel production methods, a push intended to lift profits while building a foundation for future expansion.

Underlying the move is a deliberate evolution in the group's identity, from a bulk materials vendor to a provider of technology-backed solutions that address shifting customer requirements and stricter environmental rules. A central element of that effort involves widening the speciality lineup, exemplified by added capacity for solution styrene butadiene rubber, a synthetic rubber that enhances durability, rolling resistance and tread wear in high-performance electric vehicle tyres.

Environmental initiatives form another pillar. Facilities built by the company can trap approximately 76,000 metric tonnes of carbon dioxide each year, while separately developed technology turns recycled acrylonitrile butadiene styrene sourced from scrapped household appliances into automotive-grade interior components that satisfy performance standards and generate fewer emissions than conventional methods. The group has also joined forces with POSCO Future M and BEI on anode-free lithium-metal battery development.

Parallel technology-focused programmes are underway at affiliated units. Kumho P&B Chemicals is formulating water-based epoxy resins that curb volatile organic compound releases while incorporating more bio-based inputs to reduce carbon intensity. Kumho Mitsui Chemicals is advancing bio-based polyurethane systems and electric vehicle materials, alongside debottlenecking work to add 100,000 tonnes of annual methylene diphenyl diisocyanate capacity. Kumho Polychem, meanwhile, is targeting ethylene propylene diene monomer through low-temperature polymerisation paired with energy-efficiency improvements.

Birla Carbon has confirmed a price increase of up to 15 percent for its Speciality Materials products across Asia, scheduled to take effect on 1 October 2026. The company pointed to significant and sustained rises in feedstock costs, driven partly by ongoing geopolitical instability and disruptions in global feedstock markets, as the reason behind the adjustment.

Although Birla Carbon pursued operational efficiencies, supply chain optimisation and disciplined cost management to soften the impact, the scale and persistence of the cost escalation left a price adjustment unavoidable. The company's sales teams will engage customers directly to explain the details and help them navigate the transition.
