        01/HY Series Composite polyether >>

        HY series polyurethane hard foam combination polyether is widely used in refrigerators, freezers, plates, garage doors, containers, cold storage site spraying, beer cans, water heaters, building insulation and other fields, as insulation materials.

        According to hydroxyl value and viscosity, the products are divided into cyclopentane LBA type combination polyether, cyclopentane 245FA type combination polyether, cyclopentane type combination polyether, Appearance: brown-yellow viscous liquid, no solid impurities.

        The manual foaming conditions of refrigerators and freezers are shown in the table
