BIOPURethane® Spray Foam is a highperformance bio-based Polyurethane insulation foam developed for advanced thermal and acoustic applications in the building envelope. The formulation is based on aromatic isocyanates and renewable polyols obtained from vegetable sources, providing a balanced combination of mechanical strength, thermal efficiency, and sustainability.
Its closed-cell microstructure ensures excellent dimensional stability, very low water absorption, and outstanding insulation capacity. Depending on the targeted application, the foam can be adjusted in density, reactivity, and expansion to fit spray, injection, or sandwich processes. bioPUR offers fast installation, excellent adhesion to most construction substrates, and durability compatible with the service life of high-performance façades (30–40 years).
bioPUR insulation foams are based on aromatic polyurethane chemistry, produced from reactive components (isocyanates and polyols) that fully react during foaming, forming an inert solid material free from volatile monomers. Once cured, the foam is non-toxic, emits very low VOCs, and complies with REACH and RoHS regulations.
Standard handling precautions should be followed when processing the liquid components before foaming: use of gloves, goggles, and adequate ventilation is recommended to avoid exposure to isocyanate vapours. After curing, no specific hazards are expected under normal service conditions.
In case of fire, degradation of aromatic polyurethane may release carbon monoxide (CO), carbon dioxide (CO₂), and nitrogen oxides (NO). bioPUR residues and offcuts can be mechanically recycled or chemically depolymerised into polyols for reuse, supporting circularity and reducing landfill waste.
