Fine Particle-Size Carbon Source
Micronized Pentaerythritol for Intumescent Flame Retardant Systems
Fine particle-size powder engineered for stable dispersion and char-forming performance in intumescent systems.
1000 Mesh / 25.4umFunctional Role in IFR Systems
Micronized pentaerythritol is a fine particle-size powder used as a carbon source and char-forming agent in intumescent flame retardant systems, especially APP-based formulations.
Its controlled particle size supports stable dispersion in coatings, plastics, masterbatch and textile coating systems, helping formulators reduce agglomeration and improve processing consistency.
We provide application-oriented grade recommendations, sample support and technical documents to help customers match the right powder specification for testing and production.

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.
APP (Ammonium Polyphosphate)
Decomposes to provide acid source and promote char formation.
Pentaerythritol
Acts as carbon source, generating stable char structure.
Melamine
Releases non-flammable gases to expand and stabilize the intumescent layer.
