Foam Selection and Compatibility with Lamination Processes
topic
Polyurethane foam type including flexible, semi-rigid, and memory foam variants determines compatibility with flame lamination through the foam cell structure, skin thickness, and combustion characteristics that govern the melt behaviour under flame, with ester-based PU foams being preferred for flame lamination from their cleaner melt and better adhesion compared to ether-based foams, while FR-grade foams modified with flame retardant additives require adapted lamination conditions from their altered thermal properties.
Role
Determines the achievable flame lamination bond strength and process conditions through foam polymer chemistry and cellular structure that govern how the foam surface responds to flame heating, with foam specification being the primary material variable in flame lamination process optimisation that must be established before the flame intensity and speed settings can be correctly determined for each foam-textile combination in automotive and garment padding laminate development.
