  • Introduction

    DQT-501C is spray blend polyols blowing agent is 365mfc/245fa instead of HCFC-141B it reacts with isocyanate to produce foam which has excellent performances which are as follows
    1) fine and uniformity cells
    2) low thermal conductivity
    3) perfect flame resistance
    4) good low temperature dimensional stability.
    It applies to all kinds of thermal insulation engineering which uses the spray technology such as cold rooms pots large-scale pipelines and construction metope etc.
