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 layer.
Use :
In plastics(pp, pvc, pe, etc. ), polyester, rubber, and expandable fireproof coatings.
Packing : 25kg woven bag with plastic liner.
Is a nitrogen containing halogen-free environmentally friendly flame retardant, which is a type II polyphosphate. This product has a high degree of polymerization, good thermal stability, low moisture absorption, and low addition amount, can help reducing costs.
It is different from halogenated flame retardants. During the combustion process, the product expands the carbon layer to achieve heat insulation and air isolation, to achieve the flame retardant effect. It is low smoke, low toxicity, and no melting droplets. It is an efficient inorganic environmentally friendly flame retardant material.
The pH value is close to neutral, without corrosion to production equipment, reducing equipment maintenance costs. It can work synergistically with aluminum hydroxide, resulting in better results
Type II polyphosphate has a wide range of applications, including fireproof coatings for buildings, ships, trains, and cables. It is also the main raw material for compounding flame retardants such as plastics and rubber. It is also suitable for materials such as plastics (PP, PE, PVC, etc.), polyester, rubber, and various high-end intumescent fireproof coatings.

Key properties:
1, low water solubility gd-app101 has low water solubility which makes it useful in application where the product is exposed to high humidity conditions or water.
2, high phosphorus content -gd-app101 contains 72.5% phosphorus (as p2o5) which makes it a very effective fire retardant.
3, nearly neutral ph-gd-app101 can be neutralized or brought to the alkaline side by the addition of small amounts od ammonium hydroxide.
4, non-halogen-gd-app101 is a highly effective non-halogen fire retardant.
Applications:
Gd-app101 is an effective fire retardant for applications such as:
1, intumescent latex and solvent based paints.
2, intumescent mastic, caulks and putties.
3, polymer systems such as polyethylene, polypropylene, polyurethane,
4, rubbers, acrylics, polyterephthalate.
5, building materials such as wall coverings, ceiling tiles, roofing products, wall panels, wood chip board.
