Abstract: Flame laminable additive, flame retardant, and polyester polyol were added to polyether flame bonding foam to improve the bonding strength and flame laminable properties. The mechanism of flame lamination was also investigated. The research showed that the reactive flame laminable additives provided excellent adhesion properties and bond strengths with no negative influences on the other physical and mechanical properties. It was also found that the types of additives and fabrics, flame intensity, TDI index had impact on the peeling strength.

Key words: flexible foam, flame laminable additive, peeling strength, polyether polyurethan
