Product Description
SDB2237 is an environmentally friendly rigid polyurethane foam polyether specially used for the production of discontinuous panel.It used together with isocyanate(PM-200) to make rigid PU foam through PU injection foam machine. The foam produced has the characteristics as following:
Using LBA as a foaming agent is energy-saving and environmentally friendly.
Low thermal conductivity and good thermal insulation.
High compressive strength, good filling properties and uniform density distribution.
Good heat resistance and long service life.

Usage Attentions
It is recommended to control the temperature during foaming,Including mold temperature, material temperature, environmental temperature and so on.
It is recommended to place the finished sandwich panel in an environment of no less than 20 ºC for at least 24 hours to avoid significant thermal expansion and contraction caused by excessive temperature changes in the environment.
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.
Safety Precautions
Direct contact with SDB2232 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.
