BASF develops material for window shapes with high thermal insulation

 BASF SE has developed new a material for window profiles with high thermal insulation based on engineering plastic Ultradur.

Ultradur (PBT, polybutylene terephthalate), modified for co-extrusion with PVC, that replaces steel in PVC windows as the stiffening element.

The outcome is impressive because the window is equally strong while being lighter and more cost-effective. Its insulation performance is also superior, with the Uf value being significantly reduced by 0.1 W/(mK).

Ultradur simplifies production and cuts costs

The BASF plastic Ultradur is put to use in numerous industry applications in high-grade and highly stressed technical components. The material specially developed from an Ultradur blend reinforced with glass fibres offers profile manufacturers and window constructors numerous advantages.

“With its simplified production and cost-effectiveness, our new Ultradur gives both profile manufacturers and window constructors a competitive edge in the marketplace,” said Dr Kay Brockmuller, project manager construction at BASF.
