Product Description

VI-R02 High Density PU Blend Polyols for Spray Foam Insulation

VI-R02 Blend Polyols is a specialized spray foam formulation appearing as a pale yellow to brown yellow transparent viscous liquid. When reacted 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 (≤0.024 W/m.K)
Excellent flame resistance with oxygen index ≥26
Superior low temperature dimensional stability
High compressive strength ≥3000 MPa
Low water absorption ≤3%
