For businesses involved in the production of polyurethane products, the procurement of high-quality polyols is a fundamental step that directly impacts the performance and cost-effectiveness of their final items. As a dedicated manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers insights into the critical considerations for manufacturers when purchasing these essential chemical components.

When you intend to buy polyols, understanding the specific requirements of your application is the first and most important step. For instance, rigid polyurethane foam used in insulation demands polyols with a particular set of characteristics. These typically include a specific hydroxyl value, which determines the degree of cross-linking and thus the foam's structural rigidity and thermal insulation capabilities. Our range of two-component polyurethane rigid foam spray blend polyols, for example, is precisely engineered with hydroxyl values in the 170-220 GKOH/G range to facilitate superior foam formation.

Beyond hydroxyl value, other specifications such as acid value, viscosity, and moisture content are critical. A low acid value (<2 mgKOH/G) is desirable to prevent unwanted side reactions that could compromise foam quality or processing. Viscosity, often in the 800-1200 CPS/25°C range for spray applications, dictates how easily the polyol can be handled and dispensed, impacting manufacturing efficiency. Low moisture content (<0.15%) is essential to avoid the premature generation of carbon dioxide, which can lead to foam defects.
