In the chemical industry, understanding the diverse applications of core compounds is vital for informed procurement and product development. Diammonium Phosphate (DAP), known for its agricultural utility, also possesses significant industrial applications, most notably as an effective flame retardant. As a dedicated manufacturer and supplier of industrial chemicals, NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality DAP suitable for a range of flame retardant applications. This article delves into the mechanism by which DAP functions as a flame retardant and highlights why sourcing from a reliable chemical manufacturer is crucial.

The Flame Retardant Mechanism of Diammonium Phosphate

Diammonium Phosphate (CAS 7783-28-0) is a widely used intumescent flame retardant. Its effectiveness stems from a multi-stage process that occurs upon exposure to heat:

  1. Decomposition and Gas Release: When heated, DAP decomposes into ammonia and phosphoric acid. The release of ammonia gas dilutes flammable gases in the vapor phase, effectively starving the flame of fuel.
  2. Char Formation: The phosphoric acid released acts as a catalyst, promoting the dehydration and decomposition of cellulosic materials (like wood or paper) into char. This char layer forms a protective barrier on the surface of the material.
  3. Intumescence: The char layer, often formed in conjunction with other intumescent agents, swells and insulates the underlying material from heat and oxygen. This physical barrier significantly slows down or prevents combustion.

This mechanism makes DAP particularly effective in treating materials like wood products, textiles, paper, and certain plastics to improve their fire resistance. For manufacturers needing to meet strict fire safety standards, investing in high-quality DAP is essential.

Industrial Applications Requiring Flame Retardancy

The flame-retardant properties of Diammonium Phosphate are leveraged across several industries:

  • Wood Treatment: DAP is used to impregnate wood and wood-based products, rendering them less flammable and suitable for construction or furniture applications where fire safety is a concern.
  • Textile Finishing: Fabrics, especially those used in upholstery, curtains, and protective clothing, can be treated with DAP to enhance their flame resistance.
  • Paper Products: Paper and cardboard intended for specific uses, such as in electrical insulation or packaging for sensitive goods, may incorporate DAP for fire protection.
  • Fire Extinguishers: DAP is a primary component in many dry chemical fire extinguishers (often designated as 'ABC' extinguishers), capable of putting out fires involving ordinary combustibles, flammable liquids, and electrical equipment.

When you buy Diammonium Phosphate for these applications, it's crucial to ensure it meets the required purity and particle size specifications for optimal treatment and efficacy.
