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.

Nouryon, a leading supplier of organic peroxides and a developer of organic peroxide solutions, has formally announced the completion of capacity expansion of its organic peroxides manufacturing facility in Ningbo, China.

The company's production capacity for Perkadox 14 and Trigonox 101 organic peroxide products, which are crucial components for altering polymer characteristics and crosslinking rubbers and thermoplastics, has increased to 6,000 tonnes each as a result of this capacity expansion. Furthermore, by improving the qualities of recycled polypropylene (R-PP), these solutions can also allow consumers to employ recycled polymers in applications that were previously exclusive to virgin plastics.

Alain Rynwalt, Senior Vice President – Performance Materials, Nouryon, said, “Nouryon is a world leader in essential ingredients for the polymer industry and this expansion highlights our dedication to supporting our customers’ growth across the entire polymer cycle. Customer interest in improving the properties of recycled polypropylene continues to rise, in line with increased consumer awareness and more stringent regulations.”

Our customers rely on our existing network of manufacturing facilities and innovative technologies, and we are pleased to build more capacity to meet growing customer demand around the world.”

Trinseo, a speciality materials solutions provider, has signed agreements to supply its polycarbonate technology license as well as all proprietary polycarbonate production equipment in Stade, Germany to Deepak Chem Tech Ltd, a wholly owned subsidiary of Deepak Nitrite Limited, a diversified chemical intermediates company based in Vadodara, Gujarat, India.

The combined deals are worth USD 52.5 million. Subject to significant milestones, the business anticipates receiving around USD 9 million by the end of 2024 and an additional USD 21 million in the first part of 2025. The firm has made the decision to leave Stade, Germany, with this disposal of the production assets.

Frank Bozich, President and Chief Executive Officer, Trinseo, said, “While Trinseo recently announced its decision to exit virgin polycarbonate production, our polycarbonate technology is highly valued and the manufacturing equipment in Stade, Germany, can be utilised in India by Deepak. These are the initial steps of a strategic, collaborative partnership with Deepak, as we explore additional opportunities to leverage our technology portfolio and expand in higher-growth areas such as India.”

China's butadiene exports have experienced significant growth in recent years, particularly in 2021 and 2024. According to Sublime China Information (SCI), this surge is primarily driven by supply constraints in key regions, including the US and Southeast Asia.

Export Volume and Price Trends

In 2021, China's butadiene exports reached a historic high due to a supply gap in the US market. According to SCI, this trend continued in 2024 as reduced deep-sea cargo shipments and production challenges in Southeast Asia further tightened global supplies. From January to September 2024, China's total butadiene exports surged by 111 percent year-over-year to approximately 120.8 kilo tonnes.

The average export price of butadiene has fluctuated over the past five years. In 2023, weak demand in South Korea and competition from deep-sea cargoes led to a significant decline in export prices. However, in 2024, supply shortages from key regions drove prices to a five-year high. As of September 2024, the average export price reached USD 1,391 per metric ton, a 35 percent month-over-month increase, added SCI.

Export Destinations and Regional Dynamics

The majority of China's butadiene exports are directed to South Korea and Taiwan. In 2024, South Korea accounted for 74 percent of total exports, a significant increase from the previous year. This surge was driven by factors such as limited domestic supply and increased demand for spot butadiene.

While China's butadiene exports have been strong, the long-term potential for significant growth in deep-sea exports remains limited due to established supply chains and regional demand dynamics. Most of China's exports are currently concentrated in Northeast Asia, with limited opportunities for expansion into other regions.

Future Outlook

SCI added that 2025 China's butadiene supply is expected to be relatively sufficient, and export volumes may increase further. However, the sustained growth of exports will depend on various factors, including downstream demand in key markets, the availability of deep-sea cargoes, and the development of new production capacities in other regions.

Despite these uncertainties, China's butadiene industry is well-positioned to capitalize on global supply-demand imbalances and continue to play a significant role in the global market.
