Our laboratory performs chemical-physical, thermal, rheological and mechanical analyses on polymer materials, composites and recycled materials.
We provide comprehensive characterization services for R&D, quality control and validation of materials and processes, with prototyping from 250 g to several tens of kilograms and data compliant with international standards.
