1.Introduction 

Rigid Polyurethane Blend Polyols Foam System  for Packaging Insulation 

DBZ-502

 

 is a mixture of high activity, high molecular weight polyether poyol and different kinds of catalyst,blowing agent and other materials.  

 

React with Isocyanate to produce the foam which can absorb shock when impacted, 

main characteristics as follows:

1) water as foaming agent ,environmental protection

2)  low  density (8-10kg/m3) ,open cell

3)excellent performances of shockproof and shock absorption.

 

It applies to precision instrument, apparatus, medical instrument, optical instrument, crafts, fragile goods, glasswares and other goods foaming in site.
