SDG2102 is a high-performance rigid polyurethane (PU) foam designed for city heating and cooling pipe insulation. When combined with PM200 isocyanate, it forms a durable, energy-efficient foam with low thermal conductivity (≤0.033 W/m·K) and excellent compressive strength (≥0.3 MPa).
Key Benefits:
30+ years lifespan - Long-term insulation solution
High-temperature resistance (up to 140°C) - Ideal for heating systems
Closed-cell structure (≥88%) - Prevents moisture absorption
Energy-saving & eco-friendly - Reduces heat loss in pipelines
| Property | SDG2102 (Blend Polyol) | PM200 (Polymeric MDI) | Foam Performance |
|---|---|---|---|
| Appearance | Light yellow liquid | Brown liquid | Rigid, closed-cell foam |
| Density (25°C) | 1.10±0.10 g/cm³ | 1.22-1.25 g/cm³ | Core density: ≥60 kg/m³ |
| Viscosity (25°C) | 300±100 cps | 200±50 cps | Smooth injection process |
| Thermal Conductivity | - | - | ≤0.033 W/(m·K) at 50°C |
| Compressive Strength | - | - | ≥0.3 MPa (radial) |
| Close Cell Content | - | - | ≥88% (excellent moisture resistance) |
| Shelf Life | 6 months | 12 months | Store at 15-25°C |
Longer Lifespan - Competitors often offer 20-25 years, while SDG2102 lasts 30+ years.
Better Thermal Efficiency - Lower thermal conductivity (≤0.033 W/m·K) than standard PU foams.
Wider Temp Range - Works in -30°C to 140°C, ideal for extreme climates.
Faster Reactivity - Cream time: 10-30s | Gel time: 60-210s (reduces installation time).

Important:
Check mixing ratio before foaming.
Avoid foam leakage by proper sealing.
Store in ventilated, dry conditions (15-25°C).
Safety Precautions:
Wear gloves, goggles, protective clothing.
Rinse immediately if contact with skin/eyes occurs.
Use CO di oxide/foam fire extinguishers (non-flammable).
Storage Recommendations:
Keep in sealed, zinc-coated drums (220kg/drum).
Avoid direct sunlight & moisture.
