Groupe Maine and Benvic team up to raise the performance of PVC profiles

Benvic has developed PVC compounds resistant to high temperature. It meets an increasingly demanding market for profiles with larger windows, darker glazing or double or triple glazing. The compounds avoid shrinking, warping or cracking under temperatures exceeding the softening point for PVC. The challenge was to devise a new formulation that can be extruded on existing tools. Benvic used PVC resins with a higher Vicat point, and glass fibre to add to the stiffness to fight shrinkage and linear expansion.
