The Technical Service department of Shin-Etsu in Rotterdam and Cires, Shin-Etsu’s PVC factory in Portugal, jointly developed a new PVC product with a high molecular weight. This PVC grade is mainly used for frame seals in the window profile industry. The demand for this product is high because it offers several advantages. It does not stick, so that the glazing can easily slide into the profiles. Furthermore, with this PVC type the entire window profile is made of PVC, which makes recycling much easier in due time.
