New flame retardant for flame lamination applications

von Eric Geiger, Jody Ju

Foam to fabric flame lamination is a distinct segment of the automotive and furniture industrial applications for flexible polyurethane foams. Typically, this application requires materials that provide good properties, e. g. air-permeability, high resilience, lightweight in nature, with good adhesion and preferably good flame retardance. Typical performance requirements include meeting at least FMVSS302 for flame performance in addition to other requirements as indicated by customers.

These requirements may include a measurement of the adhesive strength of the laminated fabric upon the foam and verifying that the core physical properties of the materials have also not been affected. A new commercial flame retardant is now available for flame laminating flexible foams. This new product combines the benefit of flame retardance, improved adhesion, and resistance to scorch while providing lower volatility that would result in lower VOC emissions and lower fogging contributions while further enabling the foam to meet its expected physical properties.
