Description

Rigid polyurethane foam system for panel insulation

B2 fireproof blended polyol
continuous
Good flowability
Rapid demould

liquid component for fireproof polyurethane foam

B2 class fireproof blended polyol for polyurethane (PU) cored continuous panel

General description

The product is a mixture consisting of polyether polyols, silicone stabilizer, flame retardant and catalys, using HCFC-141b as foaming agent. It is a light yellow liquid at room temperature. It has been developed to produce B2(DIN4102-1) class fireproof polyurethane (PU) cored continuous sandwich panel in conjunction with polymeric MDI.

Typical properties:

Good flowability, density uniform

Fine and uniform cell, high closed-cell rate

High compressive strength

High and low temperature dimensional stability

Rapid demould
