SDG2104 is an environmentally friendly, water-blown rigid polyurethane (PU) foam designed for pipe insulation in heating and cooling systems. Unlike traditional foams, it uses Carbon di oxide as a blowing agent (0 ODP), making it ozone-safe and compliant with GB/T29047 standards.
Key Benefits:
Zero Ozone Depletion (0 ODP) - 100% eco-friendly, no harmful blowing agents.
Superior Thermal Insulation (≤0.033 W/m·K) - Reduces energy loss in pipelines.
High Compressive Strength (≥0.35 MPa) - Durable for long-term use.
Closed-cell content ≥90% - Excellent moisture resistance.
Fast curing (30-40s rise time) - Speeds up installation.
| Property | SDG2104 (Blend Polyol) | PM200 (Polymeric MDI) | Foam Performance |
|---|---|---|---|
| Appearance | Light yellow liquid | Brown liquid | Rigid, closed-cell foam |
| Density (25°C) | 1.08±0.10 g/cm³ | 1.22-1.25 g/cm³ | Core density: ≥60 kg/m³ |
| Viscosity (25°C) | 800±100 cps | 200±50 cps | Smooth injection process |
| Thermal Conductivity | - | - | ≤0.033 W/(m·K) (GB/T 10294-2008) |
| Compressive Strength | - | - | ≥0.35 MPa (GB/T 8813-2008) |
| Close Cell Content | - | - | ≥90% (excellent moisture barrier) |
| Shelf Life | 6 months | 12 months | Store at 15-25°C |
Eco-Friendly Advantage - Uses water-based blowing agent (Carbon di oxide), unlike competitors using harmful chemicals.
Better Thermal Efficiency - Lower thermal conductivity (≤0.033 W/m·K) than standard PU foams.
Higher Compressive Strength (≥0.35 MPa) - More durable than average pipe insulation foams.
Faster Installation - Rise time: 30-40s | Gel time: 130-220s (reduces labor costs).
| Parameter | Summer | Winter |

| Material Temp | 24-28°C | 24-28°C |
| Steel Tube Temp | 18-25°C | ≤35°C |
| Machine Pressure | ≥10 MPa | ≥10 MPa |
Important:
Mixing Ratio: SDG2104 : PM200 = 1:1.5-1.55 (weight ratio).
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 Carbon di oxide/foam fire extinguishers (non-flammable).
Storage Recommendations:
Keep in sealed, zinc-coated drums (220kg/drum).
Avoid direct sunlight & moisture.
