    COPOLYMER POLYOL LHS - 50
    General Properties and Applications:
    LHS - 50 is an inactive polyether polyol modified with a styrene - acrylonitrile (SAN) polymer with a solid content of approx 45% by weight. It effectively combines a high solid content with low viscosity. LHS - 50 can also be used for the production of conventional slabstock foams with very high load - bearing properties.
    Sampling:
    Moisture access must be prevented when taking product samples.

    Handling Precautions:
    Flash point is above 200℃(open cup method), flammable but non - explosive. In case of fire, put out with foams, dry powder, steam or water.
    When handling polyols, avoid exposure to eyes or prolong contact with the skin. If eye contact occurs, flush with plenty of water. If skin contact occurs, wash exposed areas thoroughly with soap and water.
    STORAGE:
    Recommended storage temperature (℃): 10 - 35
    Shelf life (ex works): 12 months if stored in sealed, moisture - tight containers.
    Partially used containers should be tightly resealed due to the hygroscopic nature of the product.
    Recommended temperature for processing (℃): 20 - 25.
