Polyurethanes are an important component in major appliances that consumers use every day. The most common use for polyurethanes in major appliances is rigid foams for refrigerator and freezer thermal insulation systems. Consumption of rigid foam in production of household and industrial refrigerator, further to reduce the amount of required energy for maintaining fridge temperature, would play an important role in environmental stability and conservation. Rigid polyurethane foam can be a cost-effective material that can be used to provide desired energy for refrigerators and freezers. The good thermal insulating properties of rigid polyurethane foams result from the combination of a fine, closed-cell foam structure and cell gases that resist heat transfer. In addition to this specification for polyurethanes, adhesion feature would help to build a strong and constant bond between internal and outside of refrigerator wall and it will prevent heat transferring from the internal of refrigerator and outside of it.
