UL94 V0 Flame Retardants for PU Foam: Options and Considerations

There are several flame retardants that can achieve UL94 V0 rating for PU foam, including but not limited to:

1. Phosphorus-based flame retardants such as tricresyl phosphate (TCP), triphenyl phosphate (TPP), and their derivatives.

2. Halogenated flame retardants such as decabromodiphenyl ether (DBDPE), hexabromocyclododecane (HBCD), and tetrabromobisphenol A (TBBPA).

3. Nitrogen-based flame retardants such as melamine cyanurate (MCA), melamine polyphosphate (MPP), and ammonium polyphosphate (APP).

4. Inorganic flame retardants such as aluminum trihydrate (ATH) and magnesium hydroxide (MH).

The selection of a specific flame retardant depends on various factors such as performance requirements, cost, and environmental considerations.
