| Product Introduction | A two-component pre-mixed system for on-site spray molding of rigid PU foam. After Component A (polyether polyol plus functional additives) and Component B (polymeric MDI) are mixed in proportion, the mixture is atomized and sprayed onto substrate surfaces via spraying equipment, and rapidly foams and cures to form a thermal insulation layer. |
| Product Advantages | 1. Convenient Construction, Compatible with Complex-shaped Substrates: High-pressure spray application. The foam adheres and foams onto irregular surfaces such as walls, tanks and pipelines, delivering seamless coverage without dead corners. Especially suitable for thermal insulation projects with complex structures.
Adjustable gel curing time. The material sets within minutes after spraying. Mold-free construction shortens project cycles and fits large-area operations.
Closed-cell rate ≥92% after foaming. The rigid foam features thermal conductivity of 0.018–0.022W/(m•K), providing superior heat preservation and greatly reducing heat transfer.
Firmly bonds to various substrates including metal and concrete. Foam compressive strength ≥200kPa; resistant to cracking and delamination. Maintains stable performance within the temperature range of –50 ℃ ~ +80 ℃. |
