Description
SD1133 formulated polyol is a kind of spraying polyurethane rigid foam system designed with HCFC-141B as blowing agent. It is specially used for the cold storage insulation. It contains all the raw materials and auxiliaries necessary for the production of rigid polyurethane foam including the blowing agent. It has the characteristics as following:
n The strong adhesive force, convenient construction and no seams.
n The low thermal conductivity, low water absorption and good dimensional stability.
n The long service life and good flame retardant performance.
Applications
SD1133 product is suitable used for fruits and vegetables fresh cold storage, meat and fish freezer, ultra- low temperature cold storage low temperature workshop and cryogenic tanks

Packaging：
The material is normally supplied in iron pail with Zinc coating in standard container, 220kgs/drum.
Storage Recommendations：
The SD1133 is hygroscopic and containers must be kept sealed tightly to prevent absorption of moisture, which can adversely affect processing. 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 10～25℃.
