A new energy-saving solution for home appliances – multi-component mixed foam combination polyether

With the continuous development of the home appliance industry, low cost, high performance Advanced products have also become the driving force for companies to compete for development. As the pioneer of China’s energy-saving home appliances, the task of the refrigerator freezer industry is even more arduous. Starting from October 2016, the national mandatory energy efficiency standard – “Limited Power Consumption and Energy Efficiency Levels of Household Refrigerators” will be officially implemented, which puts forward stricter technical index requirements for refrigerator freezer enterprises.

At present, most cold manufacturing industries mainly use multi-component mixing and foaming technology to solve similar problems, and the effect is better. The multi-foaming technology combines the advantages of different foaming agents, significantly improves the thermal insulation performance of polyurethane foam, and optimizes the overall cost. After a lot of research in the early stage, Wanhua Rongwei has made great progress in the technology of multi-component mixed foam composite materials. Based on the original CP foam system, it has launched a new multi-component foam composite polyether system Wanefoam RCB series products. Many important refrigerator freezer customers have successfully used it. Let’s experience the high-energy features of this type of product with everyone.

1. Excellent thermal insulation performance: Wanefoam RCB system reduces the cell size and enhances the stability through the reasonable combination of formula, which can reduce the thermal conductivity of polyurethane foam, and the thermal insulation performance advantage at low temperature is It is more obvious, so as to effectively reduce the energy consumption of refrigerator freezer products and achieve the purpose of energy saving.

2. Superior economic benefits of the product: Although the blowing agents such as 245fa or LBA in the multi-component system are expensive, the foam has higher strength due to the unique high vapor pressure characteristics of the multi-component mixed blowing agent. The Wanefoam RCB system further reduces the perfusion volume of the product through skin thinning technology and enhanced foam flow properties. After being applied to refrigerator freezers, it can achieve the purpose of reducing the overall cost of foam.

3. Improving the production efficiency of refrigerator freezer enterprises: due to the introduction of unique patented monomers into the Wanefoam RCB system, the cross-linking density of molecules has been increased; and by optimizing the combination of catalysts in the system, the release performance of the system has been improved to the greatest extent , so that customers can speed up production tempo and improve production efficiency. Lay a solid foundation for customers to increase production, reduce costs, and increase market competitiveness.

Manufacturing high-performance products and providing customers with efficient and low-cost solutions has always been the corporate purpose of Wanhua Rongwei. The use of Wanefoam? RCB series multi-component foaming system can reduce the power consumption of refrigerators and freezers by about 5% at low cost. With the gradual localization of multi-component mixed foaming agent raw materials, the cost of multi-component foaming system will be further improved. Optimization, the application on the refrigerator freezer will create higher economic benefits.
