CORALIGHT® 600: Durable, high-performance innovation in high-density polyurethane produced by upcycling

DUNA Corradini marks a significant stride in the polyurethane industry with the introduction of CORALIGHT® 600. This innovative board is manufactured via upcycling high-quality secondary production products, thus melding technical performance, sustainability, and aesthetics. The upcycling process, aligned with the 2030 Agenda, transmutes production waste into valuable resources, yielding new products with superior performance. DUNA has established a dedicated facility for industrial upcycling for the production of CORALIGHT® 600, thus actualizing a genuine circular economy.

As for its performance, CORALIGHT® 600 excels with some notable features such as excellent screw retention, low water absorption, and significant resilience.

what is upcycling?


Upcycling, also referred to as creative reuse, is a process aimed at recovering materials or products no longer in use, in order to transform them into materials or products of superior quality or utility. Unlike recycling, which often degrades the quality of materials, upcycling enhances the quality of recovered waste, giving it new life in a creative and innovative manner.

Within the context of the environment and sustainability, upcycling is a key element of the circular economy as it helps reduce the amount of waste ending up in landfills and minimizes the need for the production of new materials. This thereby contributes to reducing the ecological footprint and promotes a more responsible and sustainable consumption.


Key Advantages of CORALIGHT® 600


  • Excellent Screw Retention: Superior to wood and other recycled materials.
  • Water Resistance: Minimal water absorption, with less swelling compared to other materials.
  • Resistance to Bacteria and Chemicals: Immune to bacteriological agents, mold, and chemicals.
  • Aesthetics: High homogeneity and excellent finish for high aesthetic value applications.
  • Thermal Insulation: Ability to reduce heat dispersion and eliminate thermal bridges.
  • Ease of Machining: Easy to machine, cut, drill, cover, glue, and paint.
  • Fire Resistance: Class B2 – Euroclass E, for improved fire resistance.

Potential Applications of CORALIGHT® 600


  • Carpentry and Building Frames: Window frames and counter-frames, exterior door panels.
  • Thermal Coverings and Building Insulation Solutions.
  • Refrigeration System Panels: Sandwich panels and reinforcement panels for refrigerated vehicles.
  • Technical and Outdoor Furniture: Ideal for yachts, motorhomes, and outdoor furniture.

In sum, CORALIGHT® 600 boards epitomize a revolution in the polyurethane industry, demonstrating a success of the circular economy and a significant stride towards more sustainable production.
