Sista Polyurethane Foam is a high-performance, single-component polyurethane mounting foam. It expands and hardens upon contact with air, offering excellent adhesion properties and can be effectively used on various surfaces (concrete, metal, wood, plastic). This product provides water resistance, sound insulation, and thermal insulation capabilities. Its low expansion ratio ensures optimal filling and sealing performance. During use, it cures rapidly, enhancing work efficiency. With a temperature resistance range of -40°C to +80°C, it maintains its effectiveness across a wide temperature spectrum.
