Used as a reactive polyol in the production of polyurethane elastomers, coatings, adhesives, and sealants. Its low glass transition temperature and high flexibility make it ideal for applications requiring durability and elasticity, such as in automotive parts, footwear, and medical devices. It also enhances hydrolysis resistance in polyurethane systems, making it suitable for use in humid or wet environments. Due to its biodegradable nature, it is particularly valued in biomedical applications, including controlled drug release systems. Commonly employed in one-component moisture-curing systems due to its terminal hydroxyl groups that react with isocyanates.
