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.

Ecolomondo Corporation, a leading Canadian innovator in sustainable scrap tyre recycling technology, has announced that its new milling line at Hawkesbury facility has achieved a major milestone during recent testing by reaching a throughput of approximately 2,700 lbs per hour of recovered carbon black (rCB). This result surpasses the company’s projected target of 2,200 lbs per hour.

When the new milling line is completely operational, it should be able to process 2,200 pounds of rCB per hour and provide a particle size distribution of 96 percent between 10 and 15 microns. It is anticipated that the plant would process more than 1.5 million scrap tyres annually, recovering 1,350 MT of process gas while producing 4,500 MT of recovered carbon black, 5,400 MT of oil and 2,250 MT of steel.

The company expects the commercial production of rCB to start by the end of May 2025. After being contacted, offtake clients told the company that they were eagerly expecting a larger supply of steel, oil and rCB, said the company. Depending on end-product market pricing, the company's yearly income from the sale of these sustainable goods plus tipping fees of USD 145 per metric tonne is expected to reach USD 12.1 million, with an estimated EBITDA of 45 to 50 percent, added the company statement.

Jean-François Labbé, Interim CEO, Ecolomondo Corporation, said, “This is a major achievement that brings the Hawkesbury facility closer to full production and commercialisation.”

Global speciality chemicals company Orion S.A. has launched a new bio-circular carbon black called ECOLAR 50 POWDER to provide coatings manufacturers with a new solution for more sustainable coatings.

ECOLAR 50 POWDER, which is entirely based on bio-circular feedstock, has coloristic qualities that are on par with those of ordinary speciality carbon blacks and includes 100 percent biogenic raw material according to 14C analysis. The coloristic qualities of ECOLAR 50 POWDER, a low to medium colour furnace black, offer moderate tinting strength and medium jetness in mass tone applications. ECOLAR 50 POWDER offers equivalent coloristic performance for full-tone and tinting applications, as well as comparable wetting and dispersion characteristics to conventionally manufactured low-colour furnace blacks.

ECOLAR 50 POWDER outperformed other common specialist carbon blacks in achieving medium jetness in a solvent-borne alkyd/melamine stoving enamel system. It created a similar neutral undertone as well. When tested in a water-borne 1K PU coating system, ECOLAR 50 POWDER created a more neutral undertone and jetness that was on par with other regular speciality carbon blacks.

Tilo Lindner, Vice President Global Marketing – Speciality Carbon Black, Orion, said, “We’re leading the way in advancing carbon black to meet increasing industry demands for sustainable products. ECOLAR 50 POWDER enables coatings formulators to develop truly sustainable products in all kinds of coatings applications.”

LD Carbon has inaugurated Korea’s first and largest waste tyre pyrolysis plant in Dangjin, South Korea.

Located in the Dangjin Hapdeok General Industrial Complex, the plant is expected to begin full-scale operation next month. The plant is spread over 29,800 square metres and features two factory buildings and five silos. The plant has an annual capacity to process 50 kilotonnes per annum (ktpa) of tyre chips derived from end-of-life tyres (ELTs).

At the location, LD Carbon uses a two-step pyrolysis process, first turning ELTs into solid char and pyrolysis oil. After that, the business uses a secondary pyrolysis process to further compress the char and create recovered carbon black (rCB). It is anticipated that the Dangjin facility would generate 20 ktpa of rCB and 24 ktpa of pyrolysis oil, which is a substantial increase above the combined output of 7 ktpa at its current pilot plant in Gimcheon. When compared to traditional carbon black, the rCB generated by the technique is said to lower carbon emissions by up to 32 ktpa.

The company is planning to build plants overseas and intends to join the Asian market soon. It has also struck a 10-year offtake deal with SK Incheon Petrochem for its pyrolysis oil.
