Polyurethane Foam Systems for Spraying （（DQT-501A））
Product Introduction
DQT-501A is spray blend polyols, it reacts withisocyanate 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 temperaturedimentional 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 Properties Appearance Pale yellow to brown viscous liquid Hydroxyl Value mgKOH/g 310-380 Dynamic Viscosity (25 ℃) mpa.s 100-200 Specific gravity (20 ℃ ) g/ml 1.12-1.20 StorageTemperature 10-25 ℃ Storage Stability month 6 Recommended Ratio pbw DQT-501A blend polyols 100 Isocyanate 100-105 Reactivity Characteristics (The temperature of the system is 20℃,and the exact valuevaried depending on processing condition) Cream Time s 3-5 Gel Time s 6-10 Foam Performances items Test Method Index Spray Density Closed-cell Rate Initial Thermal Conductivity（15℃） CompressiveStrength Adhesive Strength Elongation at break Dimentional Stability 24h -20℃ 24h 70℃ Water Absorption Oxygen Index GB 6343 GB 10799 GB 3399 GB/T8813 GB/T16777 GB/T9641 GB/T8811 GB 8810 GB 8624≥35kg/m ≥90% ≤24mW/(m.K) ≥150kPa ≥120kPa ≥10% ≤1% ≤1.5% ≤3% ≥26
