Grupo Piedade uses the latest technologies available in the cork industry to produce a new generation of cork stoppers, PIETEC.
PIETEC K is a technical cork stopper obtained by individual moulding, using 0.5 to 3 mm granulates. As a result, it is more homogeneous, ensuring proper and uniform behavior at the level of mechanical performance, specifically with regard to elasticity, compression force, resistance to boiling water and liquid seal capability.
