What's the Polyether Polyols Used for Refrigerators ?
In polyurethane products, its foaming material accounts for more than 80 % of the total, which has the characteristics of low thermal conductivity and good processing performance. It is very suitable for insulation and insulation. Therefore Hot layer.
The thermal insulation layer is a key component of the refrigerator. Most of the refrigerators manufacturers adopt the field foaming process. The main raw materials are used for polyol, isocyanate and cycloralane. The lower foam forming, and by adjusting the different ratio between the raw materials, control the speed of the foam and the effect of the foam to obtain the ideal thermal insulation effect.
Among the required plastic costs, PUs account for about 40 ~ 50 % of the cost proportion.

The raw material of polyether polyol is abundant, the price of polyether polyol for conventional hard bubbles is low, and polyether -type polyurethane polyurethane has good hydrolysis.
The advantage of polyester polyol is that the foam body is large, good adhesive, high extension, and good oil resistance. The disadvantage is that hydrolysis resistance is not as good as polyether -type foam. Polyether polyol series products are mainly used to prepare hard polyurethane foam plastics, and are widely used in refrigerators, freezer, refrigerator, insulation board, pipeline insulation and other fields.
The product heating coefficients are low and stable in size. It is also an important raw material for preparing a combination of polyether. The production of polyether polyol is mainly used in polyurethane foam plastics in the polyurethane industry. The main varieties include polyoxide acrylyl alcohol and polythexyfurate polyol.
