What is the thermal insulation and fire prevention performance of polyurethane cold storage plate? Now there is a freezer that wants to use this plate.

This question is answered by Ya Bu Machinery-Cold Storage Polyurethane Field Spraying Equipment and Polyurethane Foam Material Supplier:

The thermal conductivity of polyurethane is 0.0 17-0.024, and its thermal insulation performance is better than that of extruded board and polystyrene board, so it is the best thermal insulation material at present.

The flame retardant grade of polyurethane can reach B 1, and the general requirement for cold storage insulation is B2.

At present, the thermal insulation of cold storage generally adopts on-site spraying polyurethane technology, which is faster than sticking polyurethane cold storage plates and has no joints.
