AGRU PVDF used in acid tank construction


Lightweight composite constructions are growing in importance in almost every branch of the industry. Their mechanical properties, low mass and comparatively low manufacturing costs offer great advantages over materials like stainless steel. To ensure the chemical resistance of these constructions, they are lined with fluoropolymers like AGRU PVDF sheets.
