Polyurethane foams can be separated into two distinct categories:

• Polyester
• Polyether

Polyesters are generally more durable and provide a higher load bearing capacity.

Polyethers are typically softer and less abrasive. Additionally, both are available with anti-stat and fire retardant additives for special applications.

Polyurethanes are described in terms of density and IFD or ILD (Indentation Force/Load Deflection). IFD is a measure of the foam’s compressive characteristics. The physical properties of polyurethane foams vary widely. Knowing the requirements of the product and shipping environment allows us to choose the most appropriate material.
