Refrigerator polyurethane foaming technology shows three major trends by 2025

      Opening the "China Refrigerator Industry Technology Roadmap (2025 Edition)", in the chapter on industrial technology goals, there is a description of conducting research on alternative technologies for polyurethane foaming agents, new foaming technologies with high strength and low thermal conductivity, and continuous optimization and innovation of foaming processes to promote the development and application of high-performance, low attenuation, green and environmentally friendly polyurethane foaming materials. Through these concise phrases, the development trend of polyurethane foam technology in the refrigerator industry is clearly presented - firstly, reducing the thermal conductivity of polyurethane rigid foam, secondly, improving production efficiency, and thirdly, promoting green and low-carbon transformation.

    By 2035, the proportion of green refrigerator products will reach 30%. This is also a specific goal proposed in the new refrigerator technology roadmap.

    Although the use of HFC-245fa and LBA is restricted in the European market by 2026, they still have significant competitive advantages in domestic and other export markets. Recently, with the help of Carbon Balance Technology, Sinochem Blue Sky Honeywell New Materials Co., Ltd. completed the carbon footprint accounting of three core products, HFC-245fa, HFO-1233zd (E), and HFO-1234zd (E), and obtained certification from the authoritative third-party organization TuV Nande, providing support for the low-carbon development of refrigerator manufacturers.
