About wertec gmbh
wertec gmbh is a contract chemical research and development organization (Contract Chemical R&D) based in Vienna. Its team of chemistry experts develops customized, sustainable solutions for manufacturers, in particular plant-based alternatives to petroleum-based additives for rubber and plastics processing. The portfolio includes technical application services, additive and material testing, rheological analysis, formulation and processing, as well as contract-based R&D services. Laboratory processes include compounding of PS, PE and PP, extrusion, film blowing, and lab-scale EPS foaming and molding, complemented by functional, mechanical and fire testing such as tensile strength, puncture resistance and UL 94. The focus is on the use of natural raw materials such as plant-based fatty acids (including TOFA) for hazardous substance substitution, CO2 reduction and cost optimization. The project approach spans concept and design through testing to scale-up and disposal options.
