Insulation board is made of steel coils and polyurethane foam core(high pressure injected process foaming) in the production process through at one time composite.
The processes of Polyurethane insulation panel has improved from the original artificial foaming to use high pressure foaming machine, production processing from cutting, plate, foam molding are made of the processional equipment line, so that ensure the panel with good surface, inner structure, foam density and evenness to meet quality requirements.PPGI both-side PU panels as the common panel for cold room storage,specification as follows:
- Good waterproof performance.
- Anti-aging, chemical properties and stability.
- Low thermal conductivity, good thermal insulation effect, when the polyurethane foam density to 35-40kg/m3, the thermal conductivity of 0.18~0.29w/(m/k), it is the one material for the lowest thermal conductivity insulation by currently.
