Ammonium Polyphosphate
Ammonium Polyphosphate (APP) is a highly effective, environmentally friendly, and non-halogenated flame retardant. Its unique intumescent properties, stemming from its inorganic salt structure of polyphosphoric acid and ammonia, allow it to form a protective char layer when exposed to heat. This char acts as a barrier, preventing the spread of fire and reducing smoke emission. Available in different phases (I and II) with varying thermal stability and water solubility, APP is a versatile additive for enhancing the fire resistance of numerous materials.
- Enhance fire resistance in plastics and coatings by utilizing APP's excellent intumescent properties for superior char formation, a key benefit when working with plastics and coatings.
- Achieve superior fire safety in textiles and construction materials with this non-halogenated flame retardant, a crucial aspect for meeting stringent safety standards in textiles and construction.
- Leverage the synergistic effects of APP with other flame retardant components for optimized fire protection in advanced material applications, an important consideration for synergistic effects of APP.
- Benefit from the high thermal stability and low water solubility of Phase II APP, making it ideal for demanding applications where durability and resistance to moisture are critical, reflecting the advantages of high molecular weight ammonium polyphosphate.
