The Extrusion Challenge
Traditional pentaerythritol causes processing issues.
Micronization delivers the solution.
Traditional Pentaerythritol
Coarse particles lead to screen clogging and strand breakage.
- Screen clogging and back pressure
- Irregular strands and breakage
- Poor dispersion and surface defects
- Lower loading, higher cost
Micronized Pentaerythritol
Fine, uniform particles enable smooth extrusion and stable production.
- Clean screens, stable output
- Zero strand breakage
- Excellent dispersion and surface quality
- High loading, better cost efficiency
How It Works
Strong Char. Stronger Protection.
Pentaerythritol acts as a carbon source in intumescent systems. Under heat, it promotes dehydration and crosslinking, forming a stable, expanded char that insulates the substrate and blocks heat and mass transfer.
1. Acid Activation
Under heat, Ammonium Polyphosphate (APP) decomposes to release phosphoric acid, triggering the IFR reaction.
2. Dehydration & Crosslinking
Our Pentaerythritol reacts rapidly with the acid, acting as a crucial carbon backbone to form a dense ester network.
3. Foaming
Blowing agents (like Melamine) release non-combustible gases, expanding the softened carbon layer into a thick, porous structure.
4. Char Layer
A stable, highly insulating char layer is formed, completely blocking heat and oxygen transfer to the underlying polymer.
