MULTRANOL 4050 is a 360-molecular-weight amine-based tetrafunctional polyether polyol. MULTRANOL 4050 is primarily used to manufacture rigid foams which provides excellent thermal insulation and durability in construction applications. As a tetrafunctional polyol, MULTRANOL 4050 reacts with diisocyanates to form highly crosslinked polymer networks with superior mechanical strength and chemical resistance. The rigid and closed-cell structure of foams made with MULTRANOL 4050 exhibits high load-bearing capacity and protects against moisture, making it suitable for flooring, panels and coatings where dimensional stability and water resistance are important.
