Product Introduction
Polyester polyols are based on the condensation reaction of phthalic anhydride or other polyacids with polyols. These products are specifically designed to improve performance in CASE applications, such as increased adhesion, weather resistance, mechanical strength and chemical stability. They offer good hardness, toughness and yellowing resistance for a wide range of formulation needs.

FAQ
Q: What are the advantages of polyester polyols compared to other types of polyols (such as polyether polyols) in CASE applications?
A: Polyester polyols generally offer better hardness, chemical resistance, and hydrolysis resistance, making the final product perform better in outdoor use or environments where it is exposed to water. They also tend to give products better color stability and resistance to yellowing, especially for applications that require high color stability.
Q: Are CASE products made with polyester polyols environmentally friendly?
A: Polyester polyols can be produced from renewable resources such as vegetable oil, and such bio-based polyester polyols not only reduce the dependence on fossil fuels, but also reduce the carbon footprint of the product, in line with the current market demand for sustainable materials. However, not all polyester polyols are bio-based, depending on the product description.
Q: How to select the right polyester polyol to meet the needs of a specific CASE application?
A: Choosing the right polyester polyol takes into account a number of factors, including the final properties of the desired product (such as hardness, flexibility, chemical resistance), the application environment (such as temperature range, humidity conditions), the cost budget, and whether special certifications are required (such as food safety grade, low VOC). Typically, suppliers provide technical data sheets and application guidelines, and recommend working closely with the supplier's technical support team to conduct a small evaluation to find the best match.
