How is the cold storage board insulated?

2022 / 11 / 17

With German BASF pentane B1 foaming agent, Shandong Wiskind Architectural Steel Co., LTD., the foam has high closed cell rate and good stability, and the core material after forming can reach B1 flame retardant level. The mastercard new-generation polyurethane PIR cold storage board bonded by this core material and high-strength steel plate brings the energy-saving cold storage enclosure system with lower heat conduction and higher thermal insulation performance to the user.

How to do the cold storage board insulation? Is to rely on a low thermal conductivity of the sandwich material. Commonly used sandwich materials include polystyrene foam (EPS), extruded polystyrene board (XPS) and polyurethane (PU). Among them, compared with extruded polystyrene, polyurethane has the characteristics of good dimensional stability, low thermal conductivity and better integrity, but its use is also limited by fire resistance. In recent years, polyisocyanurate (PIR) has better fire resistance than polyurethane (PU), which can reach the B1 level stipulated by the national standard. It has strong compressive resistance, low thermal conductivity, excellent dimensional stability, and has a wider application prospect.

Shandong Wiskind Architectural Steel Co., LTD., Ltd. uses a new generation of polyurethane PIR pentane B1 core material with strong thermal insulation performance, lower heat conduction, no chlorofluorocarbon emission, to meet the national B1 level fire prevention requirements, is a new generation of environmental protection quality building materials. Manufacturers who want to buy cold storage board must pay attention to distinguish the core material of cold storage board. As long as the general thermal insulation material reaches level B, it can be tested and put into market use, but the thermal insulation material of cold storage board should be selected with lower thermal conductivity and more advantageous polyisocyanurate (PIR) material.
