Why choose polyurethane rock wool board for cold storage?

Polyurethane rock wool board is widely used in cold storage, green, environmental protection, energy saving, health and other industries. The advantages of widely using polyurethane rock wool panels in cold storage are:

1. Rigid polyurethane foam is used as the lining material of the cold storage board. The advantage of polyurethane rock wool board is good thermal insulation performance. The outer wall PU is composed of SII, pvc color steel plate and stainless steel plate. The advantage is that it can prevent the temperature diffusion caused by the excessive temperature difference between inside and outside, thereby saving energy and improving the efficiency of the cold storage.

2. Polyurethane rock wool board is fire-resistant, flame-retardant and high-temperature resistant. After adding the flame retardant, the polyurethane rock wool panel becomes a flame retardant self-extinguishing material, and its softening point reaches above 250, which only decomposes at high temperature. In addition, when the polyurethane rock wool panel burns, ash will form on the surface of the foam, which helps to isolate the foam below, which can effectively prevent the spread of fire. Polyurethane rock wool board will not produce harmful gas at high temperature.

3. Due to the excellent thermal insulation performance of the polyurethane rock wool sandwich panel, under the same thermal insulation requirements, the thickness of the outer protective structure of the building can be reduced and the indoor use area can be increased.

4. The polyurethane sandwich panel has strong deformation resistance, no cracking, smooth, stable and safe surface. PU has a stable porous structure, which is basically a closed-cell structure. It not only has excellent thermal insulation properties, but also has good frost resistance and sound absorption properties.

5. After normal use and maintenance, the service life of the rigid foam plastic foam insulation structure can reach an average of more than 30 years. During the service life of the structure, the unit price of polyurethane rock wool board is higher than that of other traditional insulation materials under normal use conditions of dry, wet or electrochemical corrosion, but the increased cost will be offset by the greatly reduced heating and cooling costs.
