Product Introduction

RIGID POLYURETHANE BLEND POLYOLS FOAM SYSTEM FOR PIR CONTINUOUS PANELS DBC-402C

blended polyols reacts with isocyanate to produce PIR foam, which has good fire resistance, temperature resistance, good heat insulation, low weight and compressive strength and other advantages.It is widely used for producing continuous panels, also suits for produce fire resistance slab stock, suits for high and low pressure foam machine. the main characteristics are as follows,

1. good fire resistance

2. excellent temperature resistance and heat insulation

3. low weight

4. compressive strength

It is widely used for producing continuous panels, also suits for produce fire resistance slab stock, suits for high and low pressure foam machine.
