About this product
Product information from the supplier.
Physicochemical Properties
Hydroxyl Value: 28~56 mg KOH/g (corresponding to molecular weight 2000~4000)
Viscosity (25ºC): 500~5000 mPa·s (higher molecular weight results in higher viscosity)
Glass Transition Temperature (Tg): -70~-55ºC (depends on microstructure; higher 1,2-structure content leads to higher Tg)
Solubility: Soluble in organic solvents such as toluene, acetone, and chloroform; insoluble in water.
Reactivit: Hydroxyl groups can react with isocyanates (-NCO), acid anhydrides, and epoxides, making it a key raw material for polyurethane synthesis.
