QHB-523 Combined Polyether for Household Appliance Refrigeration

1. Description

This product is a special combined polyether for the household appliance refrigeration field, also known as two-component polyether, which is one of the core raw materials for rigid polyurethane foam. It is scientifically compounded with various components, including polyether monomers, foam stabilizers, crosslinking agents, catalysts, and environment-friendly foaming agents. At room temperature, it is a light yellow to brownish yellow viscous transparent liquid without mechanical impurities, featuring excellent fluidity, foaming stability, and demolding performance, which is suitable for the foaming of insulation layers for cabinets and doors of refrigerators, freezers, and other household appliances.

The product adopts an environment-friendly foaming system such as cyclopentane or HFC-245fa, which does not damage the ozone layer and has a low global warming potential (GWP), complying with the Kigali Amendment and the new national energy efficiency standards for household appliances in China. The rigid polyurethane foam formed after foaming has low thermal conductivity, uniform density, and good dimensional stability, which can effectively improve the refrigeration energy efficiency of household appliances and reduce energy consumption.

3. Application

This product is mainly used in the household appliance refrigeration field, and is mainly suitable for the foaming of rigid polyurethane foam insulation layers of various household and commercial refrigerators, freezers, refrigerated display cabinets and other products, including the insulation filling of refrigerator cabinets, doors and liners, as well as the overall insulation structure molding of commercial freezers.

It can meet the requirements of ultra-thin insulation layers (insulation layer thickness ≤30mm) for high-end energy-saving household appliances, and is compatible with the production processes of mainstream household appliance manufacturers such as Haier, Midea and Hisense. It can also be used for insulation foaming of small household refrigeration equipment (such as mini refrigerators and car refrigerators). It is compatible with various production methods such as multi-gun injection and reduced-pressure foaming, and the foaming parameters can be flexibly adjusted according to the production environment.
