High density foam sheets have an increased mass per unit volume, which increases their strength, rigidity, and load yielding capacity. They can bear heavy weights and pressure with ease, making them convenient for applications that necessitate robust support. In construction, high density foam sheets are used for structural insulation as it offers great thermal insulation and stability. In the furniture industry, they are used as core materials for other constituents like sofa frames and bed bases that are meant to bear heavy loads. High density foam sheets also find use in packaging for heavy machinery parts due to their strength and durability. Even with high density, these sheets are easy to cut, shaped, and fabricated to be customized for design requirements.
