The low-monomer filling and insulating foam PU EVO 400 B2 is the low-emission alternative to conventional PU foams. Its unique formulation meets high safety standards thanks to its residual free isocyanate content of less than 0.1% and saves commercial users from having to undergo mandatory PU safety training from August 2023. The white, fine-cell EVO foam is ideal for typical installation work, filling joints and insulating cavities. PU EVO 400 B2 adheres perfectly to all common building materials and many plastics and has excellent sound insulation and insulating properties. Thanks to its high dimensional stability of ± 5%, there is no need for time-consuming reworking. The non-stick safety valve allows work to be interrupted for several days.
