Citing the increase in raw material costs, specialty chemicals company Lanxess is raising its prices for 1,6-hexanediol (HDO) globally with immediate effect.
“The increase amounts to EUR 350 per metric ton. The reason for the adjustment is the significant rise in raw material costs over the past months,” said the company.
HDO is an important precursor for high performance coatings, fibers, adhesives, polyurethanes, polycarbonate diols, and as reactive diluent for epoxy resins.
The core business of Lanxess is the development, manufacturing and marketing of chemical intermediates, additives, specialty chemicals and plastics.
A new bio-based cut & chip resin for the most demanding applications.
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™ BIO-TR 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.

Kuraray Co., Ltd. marked its 100th anniversary on 24 June 2026, with a commemorative ceremony at the Tokyo International Forum. The company live-streamed the event to its domestic and overseas locations, enabling employees worldwide to join the celebration simultaneously and strengthening the Group's collective spirit.
The speciality chemical company expressed deep appreciation to its stakeholders and predecessors for their enduring support throughout the century. Leaders also reaffirmed the organisation's determination to pursue new challenges collaboratively as it embarks on its next hundred years.
Hitoshi Kawahara, President, Kuraray Co., Ltd.
President Hitoshi Kawahara called for uniting values across diverse countries, regions, languages and cultures during this pivotal moment. He advocated for realising ‘One Kuraray’ by actively connecting people, technologies and knowledge beyond conventional organisational and business boundaries to co-create fresh value.
Kuraray originated in 1926 in Kurashiki, Okayama Prefecture, with the commercial production of synthetic rayon. Over the past century, the company built its reputation on distinctive technologies, including PVA fiber, PVOH resin, CLARINO man-made leather and EVAL EVOH resin, guided by its mission to achieve what no other company can for people and the planet. Today, Kuraray operates across 32 countries and regions. The company now views its centennial as a launching point for tackling social challenges through innovation and for unlocking new possibilities in the years ahead.
Cabot Secures EcoVadis Platinum Rating For Sixth Straight Year

- June 26, 2026
Cabot Corporation has once again achieved the top-tier platinum designation from EcoVadis, maintaining this elite status for six consecutive years. This accomplishment secures the company’s place among the global elite, as only one percent of all businesses scrutinised by the rating agency receive this highest mark. The outcome reflects the firm's sustained emphasis on driving tangible environmental and social advancements while upholding rigorous disclosure standards across its operational network.
The assessment framework employed by EcoVadis examines more than 150,000 entities worldwide, spanning numerous sectors and geographies, with evaluations rooted in established sustainability benchmarks. Cabot registered its most significant annual performance jump this cycle, with a five-point increase in its cumulative score, driven largely by enhanced results in the ethical conduct segment. Additionally, the company retained its exceptional standing in both environmental stewardship and workforce rights, securing the maximum possible recognition in those two critical areas.
With EcoVadis consistently tightening its evaluation parameters to mirror emerging global norms, Cabot has responded by intensifying its own internal sustainability measures. The organisation has concentrated on elevating operational effectiveness and data visibility, ensuring its practices remain responsive to the increasingly stringent expectations of stakeholders and rating bodies alike.
Underpinning this trajectory is a deeply ingrained organisational culture focused on iterative refinement and long-term value creation. By persistently elevating its sustainability agenda, Cabot reinforces its reputation as a proactive industry participant, dedicated to aligning corporate performance with broader societal and environmental objectives.
Jennifer Chittick, Senior Vice President, Safety, Health and Environment (SH&E) and Government Affairs; Chief Sustainability Officer, said, “We are encouraged by this year’s EcoVadis results, which reflect meaningful progress across our sustainability programme and our largest year-over-year score increase to date. These results demonstrate how greater transparency, stronger cross-functional collaboration and disciplined execution are helping us strengthen how we operate while advancing progress toward our 2030 sustainability goals.”
Nokian Tyres Secures 100th Place On TIME’s 2026 Most Sustainable Companies List
