As part of the trend towards a circular economy, the search for lightweight materials has become a fundamental strategy in recent years. Lighter plastics mean lighter finished products. Which become even more important in the rapid transformation occurring in the automotive industry, where the reduction of weight mirrors significant improvements in fuel economy or in the building sector, where insulation comes out as highly cost effective. In the search for lightweight materials, an interesting opportunity is given by the use of sandwich structures with a foam core, in particular with polymers and advanced masterbatch solutions.
