Product Name：Ammonium polyphosphate (APP)

Product Description：CAS号：68333-79-9

Product Details:

CAS: 68333-79-9

nature:

Ammonium polyphosphate, also known as ammonium polyphosphate or polycondensation ammonium phosphate (referred to as APP), is a high quality, high efficiency, non-toxic tasteless non-corrosive gases, moisture absorption, high thermal stability, excellent performance of non-halogen flame retardants . Is a variety of intumescent fire retardant coating and flame retardant products will increase the fire additive. I plant the use of international advanced multi-layer microcapsule coating process, phosphorus content, high nitrogen content, with good thermal stability, water-soluble small, nearly neutral, high flame-retardant advantages. The product is a white powdery solid, non-hygroscopic, non-flammable, crystalline II, and has a high molecular weight (n> 1000) and high stability, it can also be used as intumescent flame retardant thermoplastic main active ingredient. Our products do a surface treatment, anti-hygroscopicity stronger, PH value was alkaline, water-soluble lower (less than 0.1g / 100cm3 water 25 ℃).

The flame-retardant principle:

APP dehydration at high temperature dehydrogenation to produce polyphosphoric acid or metaphosphoric acid, can be used as a strong dehydrating agent and carbonization in the flame retardant system, dehydration and the formation of elemental carbon layer through the gas source generated by the role of non-flammable gas expansion Carbon layer to cut off the air, block the fire source, to achieve the purpose of flame retardant.

Features:

1. High degree of polymerization of phosphorus and nitrogen, flame retardant effect.

2. High degree of polymerization, water solubility is low, moisture absorption is small.

3. PH close to neutral, good thermal stability, good compatibility.

4. Increase the flow of powder.

5. Thereby improving the swellability at the time of burning.

use:

1. For the preparation of a variety of high-performance intumescent fire retardant coating can be used for high-rise buildings, ships, trains, cable fire treatment;

2. For wood, plywood, fiberboard, paper, fiber flame retardant treatment;

3. Main flame-retardant additive for intumescent flame retardant (IFR) of plastics, resin and rubber;
