Medium and low polyol resins offer distinct performance profiles suitable for different industrial requirements. Medium polyols provide harder, more chemical-resistant materials, while low polyols deliver superior flexibility and elongation. Selection depends on the desired balance between mechanical strength and elasticity in the final application.
