BaythermR microcellular foamed polyurethane rigid foam technology developed by Covestro not only has a lower thermal conductivity and better insulation performance, but also can speed up production efficiency without the need to invest in additional equipment. Using BaythermR microcellular foaming technology to make refrigerators is both energy efficient and efficient.
According to the 2018 Food Industry Annual Report of the Ministry of Economic Affairs, the total value of frozen food in 2017 was 70 billion yuan, with an output of 74.1 tons, and the growth momentum continued to rise. Despite the surge in end-consumer demand, the overall frozen food industry still faces the problem of inadequate allocation of low-temperature logistics and refrigeration-related equipment. In addition, during transportation, unstable temperature management and poor freezing efficiency may cause food to spoil, causing dietary safety issues.
More than 95% of refrigerators or freezers in the world use polyurethane rigid foam as heat insulation material. The smaller the pore size, the better the insulation performance. For this reason, Baytherm microcellular foamed rigid polyurethane foam developed by Covestro not only can reduce the foaming pore size by up to 40% compared to traditional polyurethane, but only a few microns in diameter, and can increase the thermal insulation effect by 10%. Yang Zhengyuan, Head of Polyurethane Business Unit, Covestro, Taiwan, said: "Polyurethanes play an important role in global food preservation. We hope to use Covestro to develop new technologies such as microcellular foaming on polyurethane materials to improve thermal insulation and reduce The rate of food loss has further optimized Taiwan's related infrastructure for cold chain logistics. "
Compared with other polyurethane materials used in cold chain equipment, Baytherm polyurethane rigid foam technology can exert different characteristics under different formulations. The cabinet formulation system uses Covestro's microcellular foaming technology, which not only reduces the thermal conductivity and improves the thermal insulation performance. In addition, it can be used in combination with a variety of foaming agents, and has good processability and mold release properties. The box formula system has excellent physical properties such as dimensional stability and mechanical strength. It can also moderately reduce the density of polyurethane foam and reduce the amount of raw materials injected. The door body formula system can moderately adjust the thermal conductivity and density according to customer needs to match different door body applications. Baytherm polyurethane technology can not only improve the performance of rigid foam, but also has won the favor of the home appliance industry because it does not need to invest in additional production equipment.
