STAC presents its recycled polyamide for thermal break profiles for aluminium systems

STAC's new PA 66 25GF RE recycled polyamide achieves a 70% reduction in CO2 emissions, a 60% reduction in water consumption and a 70% reduction in the use of virgin materials. After intensive research and development, STAC has successfully developed a material for thermal break profiles composed entirely of PA 66 and recycled fibreglass, coming from post-industrial streams. PA 66 is an engineering plastic suitable for use as a thermal break material in aluminium systems.

Until now these profiles have been manufactured from virgin material derived from fossil resources. The PA 66 25GF RE designed by STAC gives a second life to a polyamide from clean, homogeneous and reliable sources, which offers high precision extrusion. 25% recycled fibreglass is added to the recycled polyamide, so that the resulting final material is sustainable. The consistency of the sources used and the use of STAC's additives ensures that the same mechanical properties are maintained.

In five years, 40% of STAC’s production will use recycled materials

Currently the sources of PA 66 and recycled fibreglass are scarce. That is why STAC's R+D+i laboratory continues to work in multiple directions, working hand in hand with recyclers to expand and improve the classification of raw materials at entry to the process, with the aim of ensuring that in the next 5 years STAC achieves that 40% of its production uses recycled material.

The goal for 2028 is to reduce the environmental impact caused by the manufacture of STAC's profiles whilst maintaining their quality and reliability, and to increase the sources of recycled material to meet the growing market demand, with the aim of zero waste.

Be part of the change: „more than recycling, it is sustainability”

Sustainability is ever-present in STAC’s philosophy, throughout a product’s life cycle, from its manufacture to the point of recycling or reuse in the production process. As a result of the implementation of the integrated quality and environment system based on the UNE-EN ISO 9001 and UNE-EN ISO 14001 standards, STAC has achieved various environmental product declarations, and quality and zero waste certifications.

If you are aligned with STAC's commitment and the fulfilment of the United Nations Sustainable Development Goals (SDGs), join the company in its change. 

All standard profiles can be manufactured with recycled polyamide PA 66 25GF RE developed by STAC

Sustainability is not a passing trend; it is one of the main criteria governing the future of the market. STAC wants to accompany you in the transformation of your company toward a greater commitment to the planet and with the ever-increasing legislative requirements.
