Polyurethane foam for water heaters and coolers is applied in layers to the body of the appliances. It helps prevent heat transfer from the body, which increases operational efficiency and reduces energy consumption. The formulated polyols by Baspar Tose’e Davam Shimi Company, used in polyurethane foam for water heaters and coolers, are produced and supplied in various flame-retardant systems such as B1, B2, and B3 (normal). This company has the capability to produce different grades of polyols based on density and flame-retardant properties according to customer-defined needs. Next, we will examine the technical parameters influencing the properties of polyols used in polyurethane foam for water heaters and coolers
