Properties of PU Foams
Their properties are categorized based on the foam structure. The foam has two types of structure:
(1) Open-cell structure (2) Closed-cell structure. Open-cell structured foam is as soft as like a cushion. The cell walls, or surfaces of the bubbles, are broken up and is filled up with air that fills up all the spaces in the material.

Foam in place polyurethane foam for packaging
Polyurethane foam packaging is an open cell material, has a density of from about 8 to about 15 kilograms per cubic meter, which is primarily used to protect and support lighter weight, delicate product with high fragility. The purpose of polyurethane foam in packaging is to act as a shock absorber, protecting a moving packaged object from damage as it meets impact resistance.
