Product Name:B2 Flame Retardant PU Foam
Typical characteristics:This product is a single-component polyurethane foam sealant filled in pressurized aerosol cans, primarily composed of flame-retardant polyether and polyisocyanates, along with foaming agents, foaming aids, and flame-retardant fillers. It requires a professional spray gun or dedicated nozzle for application. Combining aerosol technology and PU Foam technology, the material rapidly expands upon ejection from the can and reacts with moisture in the air or substrates containing hydroxyl groups, curing into a semi-rigid foam plastic. The cured OCF foam offers flame retardancy, filling, bonding, sealing, thermal insulation, and sound absorption.
Scope of application:Designed for construction projects, this B2-class flame-retardant foam sealant is ideal for: - Filling window/door frame gaps in indoor/outdoor decoration. - Bonding and sealing cold storage insulation panels. - Adhering and filling interior/exterior wall insulation boards.
