MULTRANOL 9139 is a 6,000-molecular-weight polypropylene oxide-based triol, specially modified with ethylene oxide. It is used in the manufacture of flexible, rigid, microcellular and integral skin foams. MULTRANOL 9139 provides excellent flow and leveling properties, good hydrolytic stability and low viscosity. It is suitable for applications requiring high load-bearing capacity and durability. MULTRANOL 9139 based foams have high strength-to-weight ratio and resistance to environmental stresses like temperature fluctuations, moisture etc. making them ideal for applications involving insulation and protection.
