BASF, together with Schill+Seilacher “Struktol” took the opportunity of the Tire Technology 2023 conference and exhibition as a platform to introduce two new product variants representing significant contributions towards saving finite fossil resources and reducing greenhouse gas emissions.
Koresin Ccycled uses the ChemCycling approach to achieve a 100 percent substitution of fossil origin feedstock with certified sustainably recycled raw materials from chemical recycling of plastic waste.
Koresin BMBcert results from a Biomass Balance approach that enables the substitution of 100 percent of fossil-based feedstock with a renewable equivalent to reducing greenhouse gas emissions significantly.
Both products are manufactured using a certified mass balance approach. For this, BASF substitutes the corresponding amount of fossil feedstock with alternative feedstock: recycled feedstock for the ChemCycling approach or renewable feedstock for the biomass balance approach. The alternative feedstock is fed in at the beginning of the value chain and attributed to the final product by means of a certified mass balance method. Koresin Ccycled and Koresin BMBcert are certified according to the REDcert standard, which ensures the correct attribution of alternative feedstock in BASF’s value chain.
Each new Koresin product variant provides end users with important contributions to the circular economy by increasing the use of recycled raw materials or renewable resources. Koresin Ccycled and Koresin BMBcert are “drop-in” solutions: They are identical in quality and properties to standard Koresin, allowing customers to use them in their production without needing adjustments to their existing processes. 
With over 80 years of production, BASF’s Koresin is the industry benchmark with regard to superior tack performance, processing flexibility, reliability, high quality and uniformity. When added to the various rubber compounds during tire production, it creates a surface tackiness of the components - preventing the semi-finished products from shifting when they are joined together. The long-term tackiness also allows for a flexible storage time of rubber compounds. Koresin is applied in the manufacturing of quality and premium tires in OEM, replacement and re-treading as well as industrial and technical rubber goods worldwide.
Both companies eagerly anticipate their important roles in working together to bring these new advantages and their contribution towards advanced sustainability throughout the global rubber industry.

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.

Orion S.A., a global speciality chemicals company, has announced a global price increase for its portfolio of speciality carbon black. These changes, which are set to take effect immediately or as soon as individual contract terms permit, will see prices rise by up to 25 percent.

In a strategic move to address persistent market volatility, the company is also implementing a variable surcharge on top of the base price increase.

German chemical group WACKER has announced a price hike across its global polymers portfolio, responding directly to significant upheavals in international commodity markets triggered by the recent military conflict in the Middle East. This geopolitical instability has created pronounced distortions throughout the supply chain, leading to a sharp escalation in the costs of essential inputs. The company is experiencing substantially higher prices for crude oil and natural gas as well as for various other raw materials and logistics services.

To address this challenging economic landscape and offset the considerable burden of increased raw material and transportation expenses, the chemical group is implementing price adjustments effective 1 April 2026. The updated pricing will apply to several key product categories, specifically including polymer dispersions, a variety of resins and dispersible polymer powders. This strategic move is essential for the company to maintain operational stability and continue delivering its products reliably amidst the volatile market conditions.

The final scale of these price increases is not a fixed, across-the-board figure but will be determined by specific variables. It will largely depend on the original source of the product, with goods manufactured at the company’s European and Asian production sites being most affected. Furthermore, the terms outlined in existing customer contracts will also play a crucial role in defining the exact extent of the adjustment, ensuring a tailored approach to the implementation of this necessary price correction.
