    Low hydroxyl value polyester polyols PL series

    • The PL series is a modified aromatic polyester polyol with higher primary hydroxyl content, higher benzene ring content and higher functionalization.
    1. Detailed information
    2. Message

    The PL series products improve the mechanical properties of the products, such as tear strength, flexibility, elasticity and so on. They are suitable for leather, elastomer, binder, coating, soft foam, paving material, etc. Two-component adhesive, building sealant, self-skinning and other fields.

    Product features:

    1. This product has good solubility with polyether polyol and other components, and its composition is not stratified. It can replace or partially replace polyether polyol. It can be widely used in many fields such as high springback, self crust, elastomer and adhesive.

    2. this product can improve the tear strength and compression properties of foam;

    3. This product improves the flame retardancy and fire resistance of foam;

    4. with good thermal stability and mechanical strength, with steel, plastics and other substrate adhesion is extremely strong.

    5. the product improved the hydrolysis resistance, alkyd resistance and chemical properties of polyester, storage performance is good;
