Polyurethane Rigid Foam Used For Household Appliance
1. Introduction
Exceedfoam has good mixing property, stable foaming, excellent
fluidity, commonly used in the production of refrigerators,
kitchen, freezers insulation layer. The foam produced by the
combination of polyether and polymerized MDI has better thermal
insulation performance and low temperature dimensional stability.
