Intumescent Coating Flame Retardant Performance
topic
Intumescent textile coating performance testing evaluates the expansion ratio, char quality, and heat insulation provided by ammonium polyphosphate, pentaerythritol, and melamine intumescent systems under standardised cone calorimeter and vertical flame spread exposures, measuring peak heat release rate reduction, char height, and time to ignition relative to uncoated fabric controls.
Role
Validates halogen-free intumescent flame retardant coating systems on technical textiles as effective and environmentally preferable alternatives to halogenated treatments for architectural textiles, FR upholstery, and industrial curtaining where both fire performance and chemical safety certification are simultaneously required.
