Product Description

BLEND POLYOL SD2102
RIGID PU FOAM FOR PIPE INJECTION INSULATION
DESCRIPTION
SD2102 is a kind of blend polyol used for pipe insulation system for city heating or cooling. When it combined with isocyanate(PM200) leads to the formation of rigid polyurethane foam by using PU injection foam equipment .The foam formed has the characteristics as following:

1. The thermal conductivity is low, which can meets the requirements of city heating and energy saving.
2. Service life of the foam is very long, over 30 years.
3. High temperature resistance and good dimensional stability of the foam, the highest temperature range is 140 ºC.

ADDITIONAL INFORMATION

1. Before foaming,The ratio column of the two components must be checked,Moreover, The operator should reset the radio for a period of time.t
2. SD2102 and Polymeric MDI should be controlled temperature, Prevented the summer temperature being too high,and heated in winter.
3. Exhaust before operation, and to avoid polyurethane foam escaped from cracks.

PACKING SPECIFICATION
220KGS/drum, blue paint or zinc coating drums (Drum Weight: 18-23kg)
STORAGE RECOMMENDATIONS:
The blend polyol should be stored in the sealed container to avoid the absorption of water vapor. During the transportation, it should avoid serious shake and strong sunlight. It should be stored in ventilated place, avoiding light, water and fire.
Recommended storage temperature: 15~25ºC.
Shelf Life: 12 months

SAFETY PRECAUTIONS:
Direct contact with SD2102 type blend polyol can lead to moderate eye irritation and mild skin irritation, which can cause skin allergies. Repeated inhalation of high concentration of volatile gas will cause respiratory allergy, and should be treated immediately. Anti- inflammatory and anti-allergic treatment measures should be taken.
Please be careful in the operation to prevent contact with the skin and splash into the eye, please wear the necessary protective equipment (gloves, protective goggles, working clothes, etc.).
Once splashed on the skin or the eye, rinse with water immediately for at least 15 minutes, and the skin is washed with soapy water. Please seek medical treatment immediately after swallowed.
