Product Description
VI-R02 High Density PU Blend Polyols for Spray Foam
VI-R02 Blend Polyols is a pale yellow to brown yellow transparent liquid designed for spray foam applications. When reacted with isocyanate at specific ratios, it produces high-performance polyurethane foam ideal for thermal insulation projects.
Primary Applications
- Building roof insulation systems
- Cold storage facility insulation
- 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
