    1. Detailed information
    2. Message

    PS series phthalic anhydride polyester polyol products can improve the mutual solubility of various components of the combined polyether, and endow the products with good mechanical properties, no crystallization and no precipitation at low temperature, and excellent quality and stability. It is suitable for polyurethane PUR/PIR continuous hard / soft surface plate, intermittent board, household appliances, cold storage spraying, refrigerated car insulation, imitation wood products and so on.

    Product features:

    1. The polyurethane foam made by PS series phthalic anhydride polyester polyol product has good flame retardancy, uniform foam and fine quality.

    2. PS series phthalic anhydride polyester polyol products with high reaction activity and good adhesive properties;

    3. The series of PS products are heat-resistant, low-temperature resistant and oil-resistant;

    4. the product toughness is good, the sound insulation effect is excellent;

    5. PS series phthalic anhydride polyester polyol product can obviously reduce the thermal conductivity of foam.
