SPC-10072 Rigid Closed-Cell Spray Polyurethane Foam for Insulation

SPC-10072 rigid closed-cell spray PU foam (HFC-245fa) for thermal insulation of cold stores, walls, roofs and steel buildings. Density >=35 kg/m3, closed-cell >=90%, thermal conductivity <=24 mW/mK, compressive strength >=140 kPa, flame retardant. Two-component polyol + isocyanate, supplied with TDS/MSDS and matched spray equipment.

SPC-10072 is a fully-formulated rigid closed-cell spray polyurethane foam (HFC-245fa blown) for thermal insulation. Pre-blended with polyether polyols, surfactants, catalysts, blowing agent and flame retardant, it sprays in place to form a seamless, high-R-value insulating layer with high closed-cell content (≥ 90%), low thermal conductivity (≤ 24 mW/m·K), high compressive strength and good flame retardancy — ideal for cold stores, walls, roofs and steel buildings.

Key Features

High R-value insulation
Low thermal conductivity (≤ 24 mW/m·K) for excellent energy savings.
≥ 90% closed cells
Resists moisture and acts as a vapour / air barrier in one layer.
Seamless, gap-free
Sprays into every cavity and contour — no joints, no thermal bridges.
Strong & lightweight
Compressive strength ≥ 140 kPa adds rigidity while staying light.
Flame retardant & stable
Built-in flame retardant; dimensional stability ≤ 1.0% (−20 °C) / ≤ 1.5% (100 °C).
Fast, on-site spray
Applied with two-component spray equipment for quick, large-area coverage.
