CORALIGHT® 600

CORALIGHT® 600 is the new high-performance polyurethane board by DUNA Corradini, in line with the concept of Upcycling, the enhancement of high-quality production by-products. Thanks to the high percentage of recycled raw materials, the high-density CORALIGHT® 600 slabs combine sustainability, technical performance and aesthetic requirements. In addition to the insulation properties typical of polyurethane, CORALIGHT® 600 offers excellent physical and mechanical performances in terms of resistance, screw retention, low water absorption and workability, which make this sheet a good solution for a multitude of applications spanning from building to furnishing, including reinforcement of structural elements and of refrigerated systems.

The new CORALIGHT® 600 polyurethane boards are the most recent entries in the DUNA product range, within the broader “SFRIDO ZERO” project officially launched in 2015. The increasing commitment to sustainability has prompted us to revise our production processes and to invest in state-of-the-art technologies with a view to optimising the use of raw materials and implementing a real circular economy through the UpCycling of secondary products of production.

Perfectly aligned with the goals of the 2030 Agenda, the UpCycling process is intended to convert production waste into a valuable resource that can generate new products from waste materials, otherwise be disposed of, giving them superior properties and performances. To fully embrace this philosophy based on recovering and giving new value to by-products, the DUNA Group has developed a new industrial upcycling plant, dedicated to the production of CORALIGHT® 600 and inaugurated in July 2021.

Thanks to the minimisation of virgin raw materials waste and the reduction of the environmental impact caused by waste disposal, DUNA can now implement a comprehensive circular economy based on the conversion of its by-products into new sustainable and high-performance polyurethane materials. Blending technique and sustainability, CORALIGHT® 600 represents a win-win solution conceived to respond to the most challenging technical requirements and to support international customers in a variety of industrial sectors.
