1.Building materials Grade Charring agent is a non-toxic, mineral-based alternative to synthetic charring agents, making it suitable for environmentally friendly flame-retardant sheets. 2.When exposed to fire, Building materials Grade Charring agent dehydrates (releasing water for cooling) and forms a ceramic-like char layer, insulating the material from heat and flames. 3.Building materials Grade Charring agent Effective in polymer sheets (PP, PE, EVA, rubber), textiles, and paper—used as a filler, coating, or in composites.

Because‍‌‍‍‌‍‌‍‍‌ of its thermal stability, fibrous nature, and its ability to encourage the formation of char, Flame retardant Charring agent Powder can act as a natural and environmentally friendly char marker agent in flame-retardant sheets. In polymer sheets, rubber, or textile composites, the addition of Flame retardant Charring agent Powder results in a fire-resistant material that forms a ceramic-like char layer which keeps the underlying material insulated from heat and flames.


Sepiolite as a Flame retardant Charring agent Powder

Key Benefits:

√ Natural & Safe – Unlike artificial flame retardants, Charring agent chemical for formula is a natural clay mineral.

√ Thermal Stability – Charring agent chemical for formula Can tolerate high temperatures (>1000°C) without breaking down.

√ Char Reinforcement – Produces a strong, insulating char layer upon exposure to fire.

√ Synergistic Effects – Charring agent chemical for formula Works well with other flame retardants (e.g., phosphorus or nitrogen-based additives).
√ Smoke Low & Halogen Free - Ideal for green 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.Heat Insulation & Flame Blocking – The char layer acts as a barrier to the heat and oxygen.


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 used along 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

  • Charring agent For PP Sheet Enhances fire resistance in packaging materials.
