 “Flame Retardant Developments for the FPF Market” Mike Nagridge, ICL Industrial Products

Flame retardants play an important role in meeting code requirements as well as product performance requirements in flexible polyurethane foam (FPF) applications. ICL-IP has developed phosphorus based flame retardant products to meet the ongoing challenges of today’s market where superior performance in fire tests, foam properties, and scorch is required. Product sustainability continues to be a major criterion for product development. A series of evaluations was conducted using lab bench scale as well as some large scale testing to show improvements in flame retardant related properties at low, medium, and high densities. Reactive, polymeric, and non-reactive products were also evaluated to show benefits of each. The results of evaluations of these development products will be presented.

 “Flame Retardation of FPF: Recent Developments and Research in EMPA – Swiss Federal Laboratories” Sabyasachi Gaan, EMPA

Flexible polyurethane foams (FPF) find application in home, transportation and public / business infrastructures. FPF owing to their chemistry and open cell structure pose fire hazards. They have high heat of combustion and heat release rate capacity and also release toxic gasses during thermal decomposition and flaming. This presentation covers recent developments in flame retardants for flexible polyurethane foams and presents work on development of new flame retardant chemistries for FPF. The presentation focuses on effect of addition of these new flame retardants on mechanical, flame retardant and thermal properties of FPF.

 “Risk Assessment Tool to Evaluate TDI Emission and Migration Data in Flexible Polyurethane Foam” Jim Chapman, Bayer MaterialScience

As reported at the May, 2010 PFA conference, recent studies conducted by the International Isocyanate Institute demonstrated problems determining “free” TDI from flexible PU foam (FPF) using solvent extraction techniques. Measuring the emission of TDI from FPF to air and migration of TDI from FPF to surfaces was proposed as better representing the residual TDI that could be “bioavailable” from FPF. That work described the techniques used to measure emission and migration and showed that no detectable emitted or migrated TDI could be found from a model FPF with detectable levels of extractable TDI. This presentation describes the risk assessment approach used to evaluate the results from emission and migration testing.

 “Technology to Separate Fabrics from FPF for Reapplication in Flame Lamination Operations” Tony Gutierrez, Publibordados

This presentation describes the process used to separate rolls of flame laminated vinyl-foam, leather-foam and cloth-foam so that the recovered face material can be reapplied to a different foam substrate.
