The Dispersion Challenge
Agglomeration weakens performance.
Particle size makes the difference.
Poor dispersion leads to stress concentration, surface defects, and reduced mechanical and flame-retardant performance.

Intumescent Flame-Retardant Mechanism
Synergistic Formula. Superior Protection.
Pentaerythritol (PER) works in synergy with APP and MEL to form a stable, intumescent carbon layer, effectively insulating the substrate and inhibiting heat and mass transfer.
APP
(Acid Source)
Decomposes to generate polyphosphoric acid under heat.
+
Key Component
Pentaerythritol (PER)
(Carbon-Forming Agent)
Dehydrates and forms a carbonaceous backbone, providing structural integrity to the char layer.
+
MEL
(Blowing Agent)
Releases non-flammable gases to expand the carbon layer.

Efficient Intumescent
Carbon Layer
Dense, continuous char layer is formed to protect the underlying polymer.

Four Core Benefits
Engineered for performance.
Proven in compounding.
1
Preserved Mechanical Properties
Maintains high tensile strength and impact performance even at high loading.
Typical retention: >90% tensile strength, >80% impact strength
2
High Thermal Stability
Withstands high processing temperatures without degradation.
Processing stability up to 280-300 °C (depending on grade)
3
Anti-Blooming / Low Exudation
Excellent compatibility and low hygroscopicity minimize blooming and surface defects.
Cleaner surfaces, better aesthetics, fewer rejects.
4
Intact Char Formation
Promotes cohesive char layer that insulates and protects the underlying polymer.
Improved flame retardancy and fire safety.
