Polyurethane Foaming Machine

Polyurethane foaming machines are compact, easy-to-use systems designed for on-site insulation, waterproofing, and protective coating applications. Unlike industrial PU foaming machines, these small units provide flexibility, mobility, and reliable spraying performance for localized construction, renovation, and energy-saving projects.
