Extrusion International USA 1-2020

38 Extrusion International 1/2020 MATERIALS Modern insulation is a key to effective climate protection, and this also applies to window profiles in new and renovated buildings. BASF has developed an Ultradur ® (Ultradur ® B4040 G11 HMG HP green 75074) that can be used for co-extrusion with PVC and is now available with a significantly improved property profile. With this new Ultradur ® grade, PVC window profiles can be mechanically stiffened in the co-extrusion process. Compared with steel stiffening, the profile is lighter and can be produced at lower cost without compromising on stability and with improved insulation. Slimmer geometries are also potentially possible For the Windows of the Future – New Ultradur ® Grade improves the Properties of PVC-Window Profiles NewUltradur ® grade improves the insulating properties of window profiles.
