Product Description
VI-R02 High Density PU Blend Polyols for Spray Foam Insulation
VI-R02 is a high-performance spray blend polyol system formulated for building construction insulation applications. This pale yellow to brown viscous liquid reacts with isocyanate to produce rigid polyurethane foam with excellent thermal insulation properties.
Key Applications
- Building roof insulation projects
- Cold storage facilities
- Large-scale pipeline insulation
- Irregular shaped thermal insulation projects
Product Advantages
- Smooth and uniform cell structure
- Low thermal conductivity (≤0.024 W/m.K)
- Excellent flame resistance (oxygen index ≥26)
- Superior low temperature dimensional stability
- High compressive strength (≥3000 MPa)
