Abstract
A flexible foam composition includes a flexible foam body having a surface, which flexible foam is polyurethane and/or latex flexible foam, and an expandable graphite layer on the surface or within the foam surface adjacent to the surface. The flexible foam composition with the expandable graphite layer imparts improved flame retardant properties to the composition.
Claims20
A flexible foam composition comprising:
- a cured flexible foam body having at least one surface, the flexible foam body selected from the group consisting of polyurethane flexible foam, latex flexible foam, and combinations thereof;
- and
- an expandable graphite layer applied to the cured flexible foam body on the at least one surface, wherein the expandable graphite layer includes an adhesion agent comprising a water-based binder, water, and a surfactant;
- the adhesion agent adhering the expandable graphite layer to the cured flexible foam body;
- wherein the flexible foam composition further comprises an antimicrobial package, aluminum trihydrate, and at least one plasticizing agent.
