EXTRUSION PROFILE AND METHOD OF PRODUCTION THEREOF

摘要

An extrusion profile comprising a thermoplastic polymer is disclosed. The thermoplastic polymer, preferably polyamide, more preferably reinforced with glass fibers is characterized in that the polymer contains pores, having an average size of about 0.1 to 0.5 mm and that its density is at most 1 g/cm³. The profile is suitable as heat-insulating fastening web, in particular for the production of windows based on metal profiles.
