Product Description
VI-R02 High Density PU Blend Polyols
High-performance polyurethane blend polyols specifically formulated for spray foam insulation applications in building construction. This pale yellow to brown viscous liquid delivers exceptional thermal insulation properties and dimensional stability.
Product Overview
VI-R02 Blend Polyols is a specialized formulation that reacts with isocyanate to produce high-density spray foam insulation. The resulting foam features smooth, uniform cell structure with low thermal conductivity and excellent flame resistance.
Primary Applications
- Building roof insulation projects
- Cold storage facilities
- Large-scale pipeline insulation
- Irregular thermal insulation applications
