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.

Scandinavian Enviro Systems AB publ has signed a letter of intent with an undisclosed partner to explore the possibility of licensing its advanced tyre pyrolysis technology for deployment in North America.

The collaboration will focus on conducting a comprehensive feasibility study to evaluate the technical and commercial viability of establishing one or multiple facilities dedicated to processing end-of-life tyres using Enviro’s proprietary method. This study is designed to provide the potential licensee with the necessary insights to assess the prospects of entering into a long-term commercial arrangement and formal technology licensing agreement.

It is important to note that any definitive agreements will depend entirely on the study's outcomes and subsequent negotiations. At this stage, there is no guarantee that the evaluation will lead to binding commitments or that the proposed transaction will ultimately materialise.

Fredrik Aaben, CEO, Scandinavian Enviro Systems, said, “We continue to see strong international interest in Enviro’s technology, and this letter of intent is yet another proof of this.”

Kraton Corporation, a leading global producer of speciality polymers and high-value bio-based chemicals derived from pine wood pulping co-products, a global price increase for all polymer products with effect from 1 April 2026. The price hike will range from USD 440 per MT to USD 700 per MT, or as individual contract terms permit, with the exact price change varying according to the polymer type and production location.

The driving forces behind these significant pricing actions are multifaceted, rooted in substantial disruptions to global supply chains. These disruptions are largely attributed to the ongoing conflict in the Middle East, which has had a cascading effect on logistics. Compounding this issue are the sharply rising costs associated with transportation and essential raw materials.
