Product Description Open/closed PU Polyurethane Foam for Building Wall Spray foam Insulation PU Foam Chemicals for Spray InsulationDQT-501C is spray blend polyols, blowing agent is 365mfc/245fa instead of HCFC-141B, it reacts with isocyanate to produce foam which has excellent performances, which are as follows, 1) fine and uniformity cells 2) low thermal conductivity 3) perfect flame resistance 4) good low temperature dimensional stability. It applies to all kinds of thermal insulation engineering which uses the spray technology, such as cold rooms, pots, large-scale pipelines and construction metope etc.Physical PropertiesAppearance Hydroxyl Value mgKOH/gDynamic Viscosity (25 oC) mpa.sSpecific gravity (20 oC ) g/mlStorage Temperature oCStorage Stability monthPale yellow to brown viscous liquid200-300100-2001.12-1.2010-256Recommended Ratio pbwDJD-105 blend polyolsIsocyanate100100-105Reactivity Characteristics(The temperature of the system is 20oC,and the exact value varied depending on processing condition)Cream Time sGel Time s3-56-10Foam PerformancesitemsTest MethodIndexSpray Density Closed-cell Rate Initial Thermal Conductivity(15oC) Compressive StrengthAdhesive Strength Elongation at breakDimentional Stability 24h -20oC 24h 70oC Water Absorption Oxygen IndexGB 6343GB 10799GB 3399GB/T8813GB/T16777GB/T9641GB/T8811 GB 8810GB 8624 >40kg/m3 ≥90% ≤24mW/(m.K)≥150kPa ≥120kPa ≥10% ≤1% ≤1.5% ≤3% ≥26
