Rigid polyurethane foam: Technical Article
Delta Poliuretani, led by a young and dynamic staff, has specialised for years in the production of materials composed of rigid Polyurethane Foam, meeting the needs of its customers in the perfect synthesis of design style and practicality of its products.
Rigid polyurethane foam
IRigid polyurethane foam is a plastic material. This gives it special characteristics, such as its incredible versatility, surprising lightness and remarkable strength. Polyurethane is technically obtained by a chemical synthesis reaction between polymers that causes them to merge into a polymer chain. Specifically, this material is derived from the chemical reaction between polyols and polyisocyanates, with the help of catalysts that speed up the chemical reaction itself, additives and surfactants. The latter lower the surface tension, resulting in the formation of foam. Depending on the density of rigid polyurethane foam, different characteristics can be identified for different purposes.
At low density, blocks, slabs, packaging and refrigeration materials useful for thermal insulation are produced.
At high density, on the other hand, there is a significant increase in mechanical strength, making the material suitable for numerous application solutions in the fields of handicrafts, modelling, design and prototyping.
Rigid polyurethane foam is rated as a Green material because it is produced with one of the lowest energy consumptions, conserving resources. It is also recyclable and reusable, which goes to help the planet and environmental sustainability
Polyurethane foams are characterised by a closed-cell structure that gives them excellent physical-mechanical properties and equally excellent thermal insulation; in addition, the foams have high adhesion properties to most materials, which makes them one of the most widely used materials and of fundamental importance for the development and industrialisation of countless products. The density of the most effective foam is about 30/35 kg per cubic metre
