Charring Agent For Sheet

Flame retardant Charring agent Powder can function as a natural, eco-friendly charring agent in flame-retardant sheets due to its high thermal stability, fibrous structure, and ability to promote char formation. When incorporated into polymer sheets, rubber, or textile composites, Flame retardant Charring agent Powder enhances fire resistance by forming a protective ceramic-like char layer that insulates the material from heat and flames.

Sepiolite as a Flame retardant Charring agent Powder

Key Benefits:

√ Natural & Non-Toxic – Charring agent chemical for formula Unlike synthetic flame retardants, sepiolite is a naturally occurring clay mineral.
√ Thermal Stability – Charring agent chemical for formula Withstands high temperatures (>1000°C) without decomposing.
√ Char Reinforcement – Forms a stable, Charring agent chemical for formula insulating char layer when exposed to fire.
√ Synergistic Effects – Charring agent chemical for formula Works well with other flame retardants (e.g., phosphorus or nitrogen-based additives).
√ Low Smoke & Halogen-Free – Charring agent chemical for formula Suitable for eco-friendly flame retardant formulations.

Mechanism of Action:

When a sepiolite-containing sheet is exposed to fire:

1.Dehydration & Char Formation – Sepiolite releases bound water (~10% by weight), cooling the material.

2.Ceramic Barrier Formation – The remaining Mg-silicate structure forms a rigid, heat-resistant char.

3.Insulation & Flame Blocking – The char layer slows heat transfer and oxygen diffusion.

Applications in Different Sheet Materials

1.Polymer Sheets (PP, PE, EVA, PVC, Rubber)

• Charring agent For PP Sheet Acts as a filler and char promoter in composites.

• Charring agent For PP Sheet Often combined with ammonium polyphosphate (APP) or melamine derivatives for intumescent effects.

2.Textile & Nonwoven Sheets

• Charring agent For PP Sheet Used in flame-retardant coatings for fabrics (e.g., automotive, protective clothing).

• Charring agent For PP Sheet Can be applied via sol-gel treatment or melt blending.

3.Paper & Cardboard Sheets
