- August 13, 2025
Japan's Kuraray Co Ltd reported a 42 percent plunge in first-half operating profit as its rubber and speciality chemicals business grappled with weakened European demand and inventory valuation losses, prompting the company to slash its full-year earnings forecast.
The Okayama-based manufacturer, known for its synthetic rubber and speciality polymers used in automotive and industrial applications, posted operating income of 26.3 billion yen for the six months ended June 30, down from 45.5 billion yen a year earlier.
Net sales slipped 2.7 percent to 400.0 billion yen, with the company's flagship vinyl acetate segment - which includes rubber-related products - bearing the brunt of the downturn as volumes declined across key markets.
"Sales volume did not increase as much as expected due to the European economic stagnation and other factors, and overall segment income decreased due to the negative impact of inventory valuation differences and higher raw material and fuel prices," the company said in its earnings statement.
The vinyl acetate division, Kuraray's largest revenue contributor, saw operating income tumble 31.9 percent to 29.9 billion yen despite maintaining sales of 202.9 billion yen. The segment includes the company's EVAL barrier resins used in food packaging and automotive fuel tanks, as well as polyvinyl alcohol (PVOH) resins with rubber-like properties for industrial applications.
Kuraray's isoprene chemicals and elastomers business, which produces synthetic rubber compounds, showed signs of recovery with operating losses narrowing to 1.3 billion yen from 4.0 billion yen a year earlier. Sales volumes increased as demand remained firm, particularly in Europe and the United States, whilst operations at the company's Thai manufacturing base stabilised.
However, the broader economic malaise weighed heavily on performance. Rising natural gas costs in the US and Europe - key raw materials for rubber production - further squeezed margins. US natural gas prices averaged USD 3.69 per MMBtu compared with USD 2.21 a year earlier, whilst European gas costs climbed to 41 euros per MWh from 30 euros.
The disappointing first-half results prompted Kuraray to revise down its full-year operating income forecast to 75.0 billion yen from an earlier projection of 90.0 billion yen, though it maintained its annual dividend at 54 yen per share.
Chief Financial Officer Hitoshi Kawamura highlighted inventory valuation differences as a significant drag on earnings, particularly affecting the company's rubber and polymer segments, where raw material price volatility has been pronounced.
Looking ahead, Kuraray expects second-half performance to improve, with operating income projected at 48.7 billion yen compared with 26.3 billion yen in the first half. The company is banking on a gradual recovery in European demand and the benefits of recent capacity optimisations.
The firm is also pursuing strategic shifts in its portfolio, including plans to expand its optical-use PVOH film production line and the acquisition of US-based Nelumbo Inc, whilst discontinuing production of certain acrylic polymers and polyester-related products.
Pirelli-Led Partnership Launches European Tyre-To-Tyre Recycling Initiative

Pirelli, Pyrum, Synthos and BASF have launched a European tyre-to-tyre recycling initiative aimed at increasing the use of recycled materials from end-of-life and scrap tyres in the manufacture of new tyres. The project, coordinated by Pirelli, is designed to establish an industrial ecosystem that supports a circular economy while reducing reliance on virgin raw materials.
The initiative uses end-of-life tyres collected across Germany from selected Driver retail outlets and motorsport activities, together with scrap tyres from Pirelli's Breuberg manufacturing plant. These materials are processed into secondary raw materials, including synthetic rubber, certified under the ISCC PLUS scheme to ensure traceability throughout the value chain before being reintroduced into the production of new Pirelli tyres.
Under the process, Pyrum converts end-of-life and scrap tyres through pyrolysis into recovered carbon black (rCB) and tyre pyrolysis oil (TPO). The recovered carbon black is upgraded and used in Pirelli's European tyre production, replacing part of the virgin carbon black requirement.
The tyre pyrolysis oil is supplied to BASF, where it is co-fed with fossil-based feedstock in the production of chemicals including butadiene and styrene. Using a mass balance approach, the recycled content is allocated to ISCC PLUS-certified Ccycled® products. Synthos then uses these materials to manufacture ISCC PLUS-certified synthetic rubber for high-performance tyre applications, which is supplied back to Pirelli, completing the material loop.
The companies said the project demonstrates that large-scale product circularity requires collaboration across the value chain rather than action by a single company. The partnership combines material science, certified processes and industrial capabilities to recover, process and reuse materials within a structured system.
According to the companies, the project represents the most comprehensive application of a tyre-to-tyre circular model in Europe to date, showing how end-of-life tyres can be transformed into raw materials for new tyre production through a traceable industrial process.

NaugaShield BIO-TR 30: A New Bio-Based Cut & Chip Resin For The Most Demanding Applications
- By TT Bureau
- July 16, 2026
NaugaShield BIO-TR 30 is SI Group’s latest advancement in bio-based performance resins designed to significantly improve cut and chip
resistance in high-severity rubber applications. With approximately 75 percent bio-based content, this innovative material delivers on sustainability targets while exceeding the performance typically associated with petroleum-derived resins, making it a strong choice for applications such as OTR tyres in mining, construction and agriculture, mining conveyor belts, rubber tracks and mill linings.
Cut and chip resistance is a complex set of material behaviours, including static mechanical strength, dynamic response under deformation and ability to withstand sharp impacts and abrasive environments. In demanding applications such as mining or agriculture, materials
must tolerate repeated high-strain loading and resist the initiation and propagation of tears. NaugaShield™ BIOTR 30 was developed precisely to meet these conditions, demonstrating notably low dynamic heat buildup and excellent tear strength – characteristics closely tied to enhanced cut and chip resistance and long-term durability under cyclical loads.
To evaluate its performance, NaugaShield BIO-TR 30 was benchmarked in an Off-road Rib Tread formulation against two widely used industry references: a gum rosin/ semi-aromatic C5/C9 resin combination and a styrenated DCPD resin. All materials were tested at an equal loading of 10 phr to provide a direct and unbiased comparison. Under these conditions, the bio-based resin consistently outperformed both alternatives, offering a stronger balance of reinforcing behaviour, improved tear propagation resistance and superior resistance to thermal degradation during dynamic flexing. Further improvements were achievable by reducing the amount of free extender oil in the compound, underscoring the resin’s adaptability in formulation design and its ability to unlock even greater performance when optimised.
These laboratory indicators were corroborated through extended Coesfeld Cut & Chip testing (see chart), in which compounds were subjected to up to 3,000 cycles at 200 rpm under a 200N applied force. Formulations containing NaugaShield BIO-TR 30 exhibited substantially lower mass loss and maintained tread surface integrity more effectively than the hydrocarbon and gum rosin-based-benchmarks. The performance advantage was even more pronounced in compounds adjusted for lower free oil content, confirming that the resin can be tailored to meet the durability requirements of the most challenging operating conditions.
The strong performance of NaugaShield BIO-TR 30 in OTR tread compounds can be readily transferred to other rubber goods that encounter similar wear mechanisms. Applications such as mining belts, agricultural and construction tracks or mill linings benefit from the resin’s ability to reinforce the rubber matrix, reduce crack growth under repeated impact and maintain structural cohesion under high-strain deformation. This versatility allows manufacturers to integrate a 75 percent bio-based resin that supports sustainability by reducing fossil-based content and helping end products last longer while maintaining – and often improving – operational performance across multiple product lines.
NaugaShield BIO-TR 30 is currently available in commercial quantities, enabling compounders and manufacturers to move directly from laboratory evaluation to pilot- and production-scale trials.
