    Reaction properties (hand test)

    Item Unit Specification
    Cream time sec 15-30
    Gel time sec 100-180
    Free rise density kg/m3 27-29

    Processing information

    Item Unit Specification
    Component temperature 22±3
    Mold temperature 55±3
    Dynamic pressure kPa 125±10
    Demold time Min >30

    It is recommended to utilize high pressure foaming machinery. The chemicals should be adjusted to the correct temperature between 20-24℃ to ensure reactivity and viscosity suitable for processing.

    The mixing pressure has to be set for both components at 120-130 bar.

    The mould temperature recommended is 50-55℃ to guarantee good foam performances.

    Foam properties

    Item Unit Specification Test standard
    Core density kg/m3 ≥40 ASTM D1622-08
    Thermal conductivity, 20℃ W/(m.k) ≤0.024 ASTM C518-10
    Compressive strength kPa    ≥140 ASTM D1621-10
    Closed cell content     % ≥90 ASTM D6226
    Water absorb % ≤3 ASTM C209-12
    Thermal stability, -30-80℃ % ≤1.5 ASTM D2126-09
    Flammability   B2 DIN 4102

    The above testing data have been generated in lab or field conditions which are typical for this application. They are believed to be correct but data variations due to varying processing or ambient conditions can not be excluded. The customer remains responsible for making his own interpretation of data and suitability of the chemicals to his particular operation.

    Handling and Storage

    DIMONDS® P1812/PIR should be protected from moisture by keeping containers sealed when not in use. Drums have to be stored indoors to protect the material from water ingress, frost and direct heat from the sun. Under temperature conditions and in properly sealed containers ,the storage life of the polyol is 6 months.

    The optimum storage temperature should be 10-30℃.

    Package

    220kg/drum or 1100kg/IBC for polyol, 250kg/drum or 1250kg/IBC for isocyanate.
