Product Description

CAS No.: 68333799 Ammonium Polyphosphate Intumescent Flame Retardant AP422 CROS484 Equal Type

 

TF-201, it is equal to Clariant Exolit AP422 for intumescent coating. is used for intumescent fireproof coating. It is widely used for paint and fire coatings on wood and construction steel, and plywood, andwood plastic composites.

 

Flame retardant mechanism of Phosphorus series flame retardant


Ammonium polyphosphate (Phase II) is a non-halogen flame retardant. It acts as flame retardant by intumescence mechanism. When APP-II is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphateester. Following dehydration of the phosphateester, a carbon foam is built up on the surface and acts as an insulation lay.

 

Charateristics:

1. Halogen-free and environmentally friendly flame retardant

2. Low water solubility, extremely low aqueous solution viscosity, low acid value

3. Good thermal stability, migration resistance and precipitation resistance

4. The particle size is extremely small, especially suitable for occasions with high particle size requirements, such as high-end fireproof coatings, textiles

Coating, polyurethane rigid foam, sealant, etc.;

5. Biodegradable into phosphorus and nitrogen compounds
