Detailed introduction

Performance and applications

The product is a combination polyether polyol, which contains polyether polyester polyol, blowing agent, homogenizing agent, catalyst, flame retardant. Expanding cross-linking agent, etc., reacting it with isocyanate of the same quality, the foam insulation and flame retardant performance generated are good, and it is suitable for spraying construction of exterior wall insulation and internal insulation

Typical performance

High closed cell rate and good waterproof performance

——— good thermal insulation effect

——— excellent fire performance
