Introduction
Clariant has unveiled its new titanium-based catalyst solutions for polyester polymerization, set to launch in 2026. This innovation aims to enhance sustainability and performance in polyester production.
Technological Advancements
The new technology reduces processing temperatures and energy consumption, while improving color value, product quality, and production efficiency. It acts as a transesterification/polycondensation catalyst across the entire polyester family, including PET, PETG, PCT, PBT, PTT, PBAT, TPEE, and emerging polyesters like PEF.
Addressing Supply Chain Challenges
Clariant's solutions address the growing market concerns over antimony availability, following China's export restrictions. By eliminating dependence on antimony, the technology offers a more sustainable alternative to traditional catalysts.
Environmental and Economic Benefits
The titanium-based catalysts are safer for the environment, with lower toxicity and reduced risk of bioaccumulation. They also offer economic benefits, such as potential CAPEX and OPEX savings through increased production capacity, reduced energy consumption, and lower wastewater treatment costs.
Industry Impact
This innovation is particularly valuable for polyester resin manufacturers, fiber producers, PET recyclers, and technology licensors. It supports brand owners in meeting evolving consumer demands and regulatory requirements for heavy metal-free polyester production.
