EXTRU-PUR

The construction industry uses more than 8 million tonnes of extruded plastic materials each year, but they often suffer from premature failure due to weathering, mechanical stress, and high temperatures. The EU-funded EXTRU-PUR project has designed and patented a disruptive extrusion technology to produce the first ever extruded products made of thermoset polyurethane. Incorporating this material is expected to increase extruded plastic durability by at least 50 %, thermal resistance by 200 %, thermal and acoustic insulation by 100 %, and mechanical strength by 30 %. Moreover, through the use of biobased Polyurethane (BioPUR) with 40-50 % of biobased content, and a novel low energy-consuming extrusion technology, a carbon footprint decrease of 60-70 % is expected.
