Rigid PU Foam :BLEND POLYOL sd237b
Product Description
sd237b is a kind of blend polyol used for rigid PU foam spray, specially used for the insulation of building external wall. When it combined with isocyanate(PM200) leads to the formation of rigid polyurethane foam by using PU spray machine. The foam formed has the characteristics as following:
1. Zero ozone depleting blowing agent
2. The strong adhesive force, convenient construction and no seams.
3. The low thermal conductivity, low water absorption and good dimensional stability.
4. The long service life

USAGE ATTENTIONS:
1.The thickness of one gun spray foam should not exceed 50 mm. If over 50mm, which may cause foam spontaneous combustion and poor foam performance.
2.It is suggested that spray next layer of the foam after the internal temperature of last spray foam blow 25ºC. And the maximum thickness spray during 24h period is 203mm(8inches).
3. Like most of foam product, foam made by sd237b is combustible. An thermal barrier must be installed in accordance with approved construction standards
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 is 15~25ºC.
SAFTY PRECAUTIONS
Direct contact with sd237b 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.).
