Footwear and Plastics Laboratory
CETEC dispone de un completo laboratorio para la caracterización, control de calidad,
desarrollo y análisis de materiales plásticos y elastómeros.
CETEC expands the equipment to offer updated services in line with changing legislative requirements.
Recently, we have incorporated an elemental analysis equipment by X-Ray Fluorescence, designed so that our customers can verify the concentration of heavy metals, in accordance with the requirements of regulations and standards, such as the requirements of the REACH regulation and the criteria for granting the EU eco-label to footwear, which limit the presence of heavy metals, which may be present in different components of footwear, such as leather and leather coatings, some plastic materials (PVC, EVA, TPU), or adhesives used in this sector.
With this technique CETEC can determine the following metals :
Ba, Sb, Sn, Cd, Bi, Pb, Br, Se, As, Hg, Au, Zn, Cu, Ni, Fe, Cr, V, Ti y Cl.
