REACH 68333-79-9 Ammonium Polyphosphate Water Based Fire Retardant

High Phosphorus Content Water Based Fire Retardant Ammonium Polyphosphate For Water Based Fire Extinguisher

Ammonium polyphosphate phase II decomposition temperature is greater than 250 ℃, with high thermal stability, so it is often used as a fire extinguishing agent and flame retardant. It can be formulated as a solution or dry powder type fire extinguishing agent, and can also be used for intumescent fire retardant coatings, intumescent flame retardant systems, etc. In the 1960s and 1970s, countries such as the United States and Canada used liquid concentrated fertilizers to fight forest fires. Based on liquid concentrated fertilizer, Chemonics Industrial Company is formulated into forest fire extinguishing agents Fir-Trol-931, Fir-Trol-934 and Fir-Trol-936 etc. The liquid concentrated fertilizer has a low freezing point, strong adhesion to plants, wood and buildings, and a good surface coverage effect on the ground surface, with less dosage and environmental friendliness. Using ammonium polyphosphate with a degree of polymerization greater than 50 as a dry powder fire extinguishing agent, its fire extinguishing efficiency and covering ability are better than general dry powder fire extinguishing agent. However, ammonium polyphosphate has not been promoted as a fire extinguishing agent, and the high cost is a major reason. In addition, ammonium polyphosphate also has certain applications in cellulose matrix materials, copolymers, and ion conduction.

TF-303 is water soluble grade APP with low chain . The cost is much cheaper than powder APP phase II. We have some customers using TF-303 for water based fire extinguisher.

Advantages

1. Good stability. Water-based flame retardant has the characteristics of good stability, not easy to decompose, not easy to volatilize, and lasting effect.

2. Good security. The water-based flame retardant can not only obtain a high degree of flame retardant effect, but also has low smoke generation and low toxicity, and the amount of toxic gas and smoke generated during fire is small, so the harm to the human body is also small.

Application

Can be prepared into 20%P-N fire-retarding liquid. It can be widely used in water-soluble flame retardant coatings, as well as high concentration binary compound fertilizers, slow-release fertilizers, ion exchangers and dispersants in the mining industry.

Used in the fire-resisting treatment of textiles, paper products, fiber, wood etc... After special treatment, it can also be prepared into high-concentration (50%) fire-retarding liquid to meet special needs.

Packing

25kg plastic woven bag with PE liner, 24mt/20’fcl without pallets, 20mt/20’fcl with pallets.

Storage

in dry and cool place, keeping out of moisture and sunshine, shelf life one year.
