Charring Agent For Aluminum Composite Panel

Aluminum Composite Panels (ACPs) are widely used in construction for cladding, signage, and insulation. To improve their fire resistance, Charring agent for technical industry can be incorporated into the polyethylene (PE) core as a natural, non-toxic charring agent, helping meet flame-retardant standards like UL94, EN 13501-1, or NFPA 285. Here’s how Charring agent for technical industry works and its benefits:

Role of Charring agent for technical industry

1.Thermal Stability & Char Formation

• Sepiolite is a naturally occurring magnesium silicate clay with high thermal stability.

• When exposed to fire, Charring agent for fire retardant coating helps form a stable, insulating char layer that protects the aluminum composite panel from heat and flames.

2.Synergy with Other Fire Retardants

• Charring agent for fire retardant coating Often used with ammonium polyphosphate (APP), melamine, and pentaerythritol in intumescent systems.

• Charring agent for fire retardant coating reinforces the char structure, improving mechanical strength and fire resistance.

3.Smoke Suppression

Charring agent for paint Helps reduce toxic smoke emissions during combustion, improving safety.

Advantages in Aluminum Composite Panels (ACPs)

• Enhanced Fire Resistance – Charring agent for paint Slows down flame spread and delays structural failure.

• Lightweight & Cost-Effective – Charring agent for paint Unlike heavy fillers, sepiolite doesn’t significantly increase weight.

• Eco-Friendly – Charring agent for paint Natural mineral, non-toxic, and sustainable compared to synthetic charring agents.

Application in ACP Fire-Retardant Coatings

• Charring agent for paint Mixed into water-based or solvent-based intumescent coatings.

• Charring agent for paint Applied as a top or intermediate layer on ACPs to meet fire safety standards (e.g., EN 13501-1, ASTM E84).
