Refined Castor Oil – Low Moisture Grade (LM)

Refined Castor Oil – Low Moisture Grade (LM) is a specialized grade of castor oil designed for applications that demand exceptionally low moisture content. This high-purity oil is ideal for processes where even trace amounts of moisture can affect chemical performance or product integrity. It is widely utilized in the manufacture of urethane blowing agents, urethane molding compounds, and the synthesis of polymers and polyurethanes.

This grade can also be derived from Pale Pressed Castor Oil, known for its light color and low acidity, ensuring both visual clarity and chemical stability.

Key Applications:

  • As a base ingredient in urethane coatings
  • In the production of polyurethane casting resins
  • Used in adhesives and printing inks
  • Functions as a chemical intermediate
  • Acts as a lubricant in industrial formulations
