Polyols - Polyester

Name Description Acid value [mg KOH/g] Hydroxyl value [mg KOH/g] Viscosity [mPas] Intended use
Polyesterol 250 Contains hydroxyl groups almost exclusively at the chain ends and is characterised by low viscosity, good miscibility with polyethers, polyesters and isocyanates. It improves resistance of products vis-à-vis hydrolysis and UV radiation. max. 2 220 - 270 2000-3500 Manufacture of various polyurethane products, such as rigid PUR foams, PUR adhesives and others.
