The cold chain is a key link to ensure food safety, drug quality and biological product activity. The logistics process of keeping goods within the appropriate temperature range by means of refrigeration, freezing, heat preservation, etc. In the cold chain logistics, the choice of insulation materials is very important, because it directly determines whether the goods can maintain the appropriate temperature during transportation, affecting the quality and safety of the goods.

In the selection of insulation materials, we need to consider factors such as insulation performance, durability, cost and actual application environment. The following are several common cold chain insulation materials and their characteristics:

1, rubber and plastic insulation material

Rubber and plastic insulation materials have excellent thermal insulation performance and low thermal conductivity, and the material is light, strong flexibility, good formability and other advantages, in the cold chain logistics is widely used to make thermal insulation boxes, thermal bags, thermal insulation pipes and so on.

2. Glass wool

Glass wool has good thermal insulation and corrosion resistance, which is suitable for thermal insulation needs in high temperature environment. Its thermal insulation effect is stable, strong compression performance, suitable for some industries with high quality requirements, such as medicine, food and so on.

3. Rock wool

Rock wool is an inorganic fiber material, not only good thermal insulation performance, but also has excellent fire performance, so it is especially suitable for places with high fire protection requirements, such as refrigerated trucks, cold storage and so on.

4. Aerogel products

Aerogel products are composite materials made of fiber and aerogel, which have the advantages of low thermal conductivity, light material, thin thickness, fire resistance, good tensile performance, etc., and can be used in cold chain insulation layer, refrigerated truck, cold storage, refrigerator, etc.

When choosing cold chain insulation materials, we also need to consider the actual application environment. For example, in high temperature and humid environments, it is necessary to choose insulation materials with good corrosion resistance; In long-distance transportation such as sea transportation, it is necessary to choose insulation materials with better seismic performance.
