Ultradur®: high-tech system for modern profile extrusion

Whether in new buildings as a Passive House Standard or the energy-efficient renovation of existing buildings, windows play a key role in building insulation. In older buildings in particular, windows and window frames, along with the roof, are responsible for the largest amount of heat loss. That is why the potential that can be exploited with new, innovative materials is so large. In combination with other measures, this contributes significantly to energy savings and thus to lower greenhouse gas emissions and better climate protection.

BASF Ultradur® has been used for many years in numerous industrial applications for high-quality technical components. A new grade of Ultradur® B4040 G11 HMG HP green 75074 has been specially developed as a heavy-duty material capable of replacing steel in PVC window profiles. With its 55% glass fibre content, it exhibits not only high rigidity and strength, but also outstanding dimensional and temperature stability: Its melting point is 195° Celsius.

Exelliq has successfully built the first toolings providing the desired high fibre orientation, smooth running capabilities and haul-off speed.
