FP 1398 is a water based flame retardant foam impregnant. FP 1398 is used to manufacture flame retardant, acoustic/thermal insulating impregnated polyurethane foam. Foam impregnated with FP 1398 will meet the requirements UL94 V0 & 94-SV, BS 476 Part 5 and BS 476 Parts 6 and 7 Building Regulations Class “O”.
|Total Solids Content, %||58.0 - 62.0|
|Viscosity, centipoise||200 - 400|
|Specific Gravity||1.45 - 1.49|
|pH||8.0 - 9.0|
The impregnated foam then passes through a drying oven at 140 - 160oC. Drying time will depend on temperature, air flow, running speed and foam thickness. Once the water has been driven off it is important that the dried film of FP 1398 is kept at ca. 150oC for 2 - 3 minutes to cross link the polymer binder to achieve optimum performance.
FP 1398 should be stored in sealed containers between 5 and 30oC. Protect from frost. FP 1398 has a shelf life of 6 months when stored correctly.
