XINFA Pentane-Based Polyester Polyols Series

Xinfa's pentane-based polyester polyol products, including XF-435, XF-390, XF-2402N, and XF-2020, exhibit excellent compatibility with alkane blowing agents through the incorporation of oily groups in their molecular structure and the selection of appropriate functionality. This results in foaming compounds with superior flow properties. The resulting polyurethane foam exhibits lower thermal conductivity and superior dimensional stability, making it widely used in the production of polyurethane insulation materials for home appliances, panels, pipes, and other applications.
