Spraying Insulation & Insulated Containers

  • Water Based Open-Cell Spray Insulation DonSpray 501F

    Water Based Open-Cell Spray Insulation DonSpray 501F

    DonSpray 501F is a two-components, spray-applied, open-cell polyurethane foam system. This product is fully water-blown foam system with good performances of low density ( 8~12kg/m3), open cell and fire resistance Class B3.

    During spray process in site, the breathing small open cell filled with air, without producing toxic gas to destroy the Ozone layer( traditional blowing agent: F-11, HCFC-141B), which is environment friendly, low-carbon new construction materials. With highly performance of thermal insulation, moisture & vapor barrier, air barrier, sound absorption, PU foam can give us a quieter, more energy saving buildings leading us to a healthier life.

  • HCFC-141B Based Spray Insulation DonSpray 502

    HCFC-141B Based Spray Insulation DonSpray 502

    DonSpray 502 is spray blend polyols with HCFC-141B as blowing agent, it reacts with isocyanate to produce foam which has excellent performances. It applies to all kinds of thermal insulation projects which use the spray, such as cold rooms, large pots, large-scale pipelines and construction out-wall or inner-wall etc.

    1. Fine and uniformity cells.

    2. Low thermal conductivity.

    3. Perfect fire resistance.

    4. Excellent low temperature dimentional stability.
