Continuous Sandwich Panel Blended Polyol

Continuous Sandwich Panel Blended Polyol

Polyurethane panel primarily consist of rigid foam as the core material, with both sides customizable for different composite materials. Classified by application, they include building insulation panels, industrial insulation panels, and decorative panels. Surface treatments encompass color-coated steel composite polyurethane panel, aluminum composite polyurethane panel, and stainless steel composite polyurethane panel. Shapes are categorized into flat panels and sandwich panels (e.g., corrugated panel). Production processes feature batch and continuous methods, with flame retardant ratings B1, B2, and B3 available as required. QHB-1201 is two components used Rigid Foam system formulatd with B2 flame retardant which is application for Continuous Curing Sandwich Panel. The foam produced has the characteristics as following: (1).Good Flatness (2).Strong Adhesion (3).Good Process Property.

Those data can be adjusted according to the customer’s request.

The above testing data have been generated in lab or field conditions which are typical for this application. They are believed to be correct but data variations due to varying processing or ambient conditions can not be excluded. The customer remains responsible for making his own interpretation of data and suitability of the chemicals to his particular operation.

Handling and Storage

220kg/drum for ZHD-8007® and 250kg/drum for Basf Isocyanate.

QHB-1201 should be protected from moisture by keeping containers sealed when not in use. Drums have to be stored indoors to protect the material from water ingress, frost and direct

heat from the sun. Under temperature conditions and in properly sealed containers,the storage life of the Polyol is 6 months and Isocyanate is 12months. The optimum storage temperature should be 10-30℃.
