IFR Synergy

Classic Intumescent Flame Retardant System

Pentaerythritol is a key carbon source in intumescent flame retardant systems.

It works synergiatically with acid source and blowing agent to form a stable, protective char layer.

01

APP (Ammonium Polyphosphate)

Decomposes to provide acid source and promote char formation.

02

Pentaerythritol

Acts as carbon source, generating stable char structure.

03

Melamine

Releases non-flammable gases to expand and stabilize the intumescent layer.
