\ud3f4\ub9ac\uc2a4\ud2f0\ub80c(EPS) <\/strong><\/p>

Polystyrene (EPS) is a traditional insulation material. With its low cost, light weight and easy processing characteristics, it is widely used in low-cost insulation demand scenarios in the cold chain industry.<\/p>

EPS accounts for about 25%-35%<\/strong> of the market in low-cost cold chain boxes, refrigerated bags and insulated packaging<\/strong>. This material is mainly used for some simpler insulation needs, especially for more economical application scenarios such as food packaging and drug transportation.<\/p>

In cold chain transportation vehicles<\/strong>, EPS accounts for about 15%-20%<\/strong> of the market. Although the insulation effect is not as good as polyurethane, its low cost advantage makes it still widely used in some transportation scenarios with low temperature requirements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Extruded polystyrene (XPS) <\/strong><\/p>

Extruded polystyrene (XPS) is a high-density, closed-cell foam material with low thermal conductivity, high compressive strength and good moisture resistance.<\/p>

XPS has a certain market share in cold chain transportation<\/strong>, about 10%-20%<\/strong>, and is particularly suitable for applications in cold chain transportation that require high compression resistance, aging resistance and moisture resistance.<\/p>

\uc5d0\uc11c wall and floor insulation of cold storage and refrigerated facilities<\/strong>, XPS has a relatively large market share of about 20%-30%<\/strong>.

Rock Wool and Glass Wool <\/strong><\/p>

Rock wool and glass wool are mainly used in high-temperature insulation and fireproofing requirements. Although they are relatively less used in the cold chain industry, their fireproof performance and high-temperature insulation properties make them still have a certain market share in specific application scenarios.<\/p>

Rock wool and glass wool are mainly used for wall, roof and floor insulation of cold storage buildings<\/strong>. In construction applications, the market share of rock wool and glass wool is about 10%-15%<\/strong>. This type of material is usually used in cold chain storage facilities with high fireproofing and insulation requirements.<\/p>

Due to the higher density and poorer insulation performance of rock wool and glass wool, they occupy a relatively small share in cold chain transportation<\/strong>, about 5%-10%<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

With the development of new insulation technologies, materials such as vacuum insulation panels (VIP) and aerogel have gained some attention in the field of high-efficiency insulation.<\/p>

The market share of these new insulation materials is still small, about 1%-5%<\/strong>, because of their high cost, suitable for high-value, special requirements of cold chain transportation, such as medicines, vaccines, electronic products, etc.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Environmental Impact Comparison<\/strong><\/p>

With the growing global emphasis on environmental standards, there is an increasing demand for eco-friendly materials in the cold chain industry. Below is a comparison of the environmental impact of various materials.<\/p>

\uc7ac\ub8cc<\/b><\/strong><\/p><\/td>

\ud3f4\ub9ac\uc6b0\ub808\ud0c4<\/strong><\/p><\/td>

Traditional polyurethane foam agents use chlorofluorocarbons (CFCs, HCFCs), which have environmental impact. However, recent developments focus on low GWP (global warming potential) or CFC-free agents to meet environmental requirements.<\/p><\/td><\/tr>

\uc8fc\ub2f9 \uc21c\uc774\uc775<\/strong><\/p><\/td>

EPS typically uses inorganic blowing agents, which are relatively eco-friendly, but recycling is difficult. New EPS materials are also exploring eco-friendly blowing agents to reduce environmental impact.<\/p><\/td><\/tr>

VIP<\/strong><\/p><\/td>

VIP does not use chemical blowing agents, and the material itself has minimal environmental impact. However, the energy consumption in production and transportation due to high vacuum technology is significant.<\/p><\/td><\/tr>

\ubbf8\ub124\ub784\uc6b8<\/strong><\/p><\/td>

Mineral wool has minimal environmental impact and is recyclable. However, it has high energy consumption in production and is relatively heavy, which hinders reducing transportation carbon emissions.<\/p><\/td><\/tr>

PVC Foam<\/strong><\/p><\/td>

PVC foam has poor environmental impact, may release harmful gases during production, and is difficult to recycle.<\/p><\/td><\/tr><\/tbody><\/table>

Polyurethane materials face certain environmental challenges, especially with the use of traditional blowing agents. However, with technological advancements, the use of low-GWP blowing agents is gradually making it more environmentally friendly. In comparison, VIP and mineral wool perform better in terms of environmental impact, but their disadvantages in price and weight limit their widespread application.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\ud3f4\ub9ac\uc6b0\ub808\ud0c4<\/strong>\u00a0remains the most commonly used insulation material in the cold chain industry due to its excellent thermal insulation, moderate density, good environmental performance, and high market penetration. Although it is more expensive, its excellent insulation performance can significantly reduce energy consumption and operational costs in the long run, providing a high cost-performance ratio.<\/p>

VIP<\/strong>\u00a0offers the best thermal insulation performance, but due to its high cost, it is suitable for high-end cold chain markets, such as biological products and pharmaceutical cold chain transportation.<\/p>

\ubbf8\ub124\ub784\uc6b8<\/strong>\u00a0\uadf8\ub9ac\uace0 PVC foam<\/strong>\u00a0are suitable for building cold chains and other sectors, but they are relatively heavy, have limited insulation performance, and have poorer environmental characteristics.<\/p>

Ultimately, choosing the right insulation material requires not only considering performance indicators such as thermal conductivity, density, and water absorption, but also comprehensively evaluating the overall cost-effectiveness of the material based on the needs of the actual application, budget, and safety requirements. Overall, polyurethane remains firmly established in the cold chain industry, especially in areas with higher temperature control requirements, and is still the preferred insulation material.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
