Product Description
VI-R02 High Density PU Blend Polyols for Spray Foam
VI-R02 Blend Polyols is a specialized spray foam formulation appearing as a pale yellow to brown yellow transparent liquid. When combined with isocyanate at specified ratios, it produces high-performance polyurethane foam ideal for thermal insulation applications.
Primary Applications
- Building roof insulation projects
- Cold storage facilities
- Large-scale pipeline insulation
- Irregular-shaped thermal insulation projects
Key Performance Advantages
- Smooth and uniform cell structure
- Low thermal conductivity for superior insulation
- Excellent flame resistance properties
- Outstanding low temperature dimensional stability
