GRANDO offers its customers a complete range of technical foams that can easily be identified by their product reference, which starts with the letters GFOAM. This range of flexible products contains all the cellular rubbers and expanded plastics most frequently used in industry.

These can be divided into two categories according to their basic chemical composition (cellular rubber or expanded plastic) and, each one, into two sub-categories according to their type of cellularisation (closed cells or open cells).
