SDB2237 is a two-component rigid polyurethane foam (blend polyol + PM200 isocyanate) designed for discontinuous sandwich panel insulation. It offers:
Ultra-low thermal conductivity (0.021 W/m·K) for energy efficiency.
High compressive strength (200 kPa) and 94% closed-cell content for durability.
Fast curing (20-30s rise time) and uniform density.
Eco-friendly (LBA foaming agent, no CFCs).
Ideal for cold storage, construction, and industrial insulation.
