Clariant’s Licocare RBW Vita range is based on rice bran wax feedstocks
than the current GTL technology that was devel- oped in the early 2000s. He went on to say that the ultimate aim is to achieve a net zero carbon footprint by transitioning to alternative feedstocks, and Sasol is seeking development partners to further these ambitions.
Wax lubricants Sasol creates novel lubricant materials by function- alising wax. These chemistry changes alter the functionality and technical benefits for the PVC converter, adding to their use in many other polymer compounds such as polyolefins, ABS, EPS, composites, and as dispersant and viscosity modifiers for colour masterbatch. At NPE 2024, Clariant showcased its latest additive solutions including Licocare RBW Vita waxes which are particularly suited to PVC and said to accelerate the transition to renewable-based products. The waxes are based on renewable bio-based rice bran wax feedstocks, a non-food raw material with at least 98% Renewable Carbon Index (RCI), and are well positioned to drive the chemical industry’s transition from fossil-based to renewable carbon materials. With superior perfor- mance and sustainability features, they are a natural replacement for traditional coal-based montan waxes and offer the same levels of lubrication, dispersion, release, and nucleation as their montan wax equivalents while helping customers achieve their sustainability targets. Clariant introduced Licolub PED 1316 at NPE, which is an oxidised HDPE wax for PVC building

applications. PVC is growing in applications such as PVC siding at a rate of 3-4% per year in the US market, said Carl Crowder, senior account manager at Clariant, and Licolub PED 1316 has been launched as an alternative to products by estab- lished US suppliers. Licolub PED 1316 is available in the Americas and domestically produced to facilitate rapid sampling and supply. US-based Valtris Specialty Chemicals has licensed a key technology in an exclusive arrange- ment to Transfar Huayang in China, as the first step for establishing sustainable alternatives to cadmi- um-based PVC stabilisers in the Asia market. The agreement will allow Transfar Huayang to use Valtris technology to manufacture and sell phenol- free over-based barium stabilisers in Asia. Qu Yaping, president of Transfar Huayang Chemicals, said: “The Valtris phenol-free over-based barium project is a comprehensive strategic cooperation project reached by the two teams’ effort on the basis of enhancing understanding and trust. Transfar Huayang fully recognizes Valtris’ technical strength and China strategy. Transfar Huayang expects more high-quality projects under negotia- tion to effectively develop soon, which will achieve mutual benefits and win-win results for both parties.” The deal involves Transfar Huayang becoming a
production partner for selected products for Valtris in the Asia market.
