Synergistic Intumescent Polyol Charring Agent Blend

Name: Synergistic Intumescent Polyol Charring Agent Blend
Brand: Chemzip
Price: 1 USD
Availability: InStock

Synergistic intumescent polyol charring agent blend is a pre-optimized mixture of pentaerythritol, dipentaerythritol, and/or sorbitol co-carbonific agents formulated to deliver superior char yield, cohesion, and thermal stability versus single-component carbon sources. The blend ratio is engineered to provide a broad decomposition temperature window that matches the acid source release profile, ensuring synchronized IFR activation. These blends reduce formulation complexity for coating and polymer compound manufacturers and are offered in grades optimized for waterborne, solvent-borne, and polymer compounding applications.
