201S Small partical size Flame Retardant of ammonium polyphosphate for textile coating
Introduction
TF201S is a kind of high degree polymerization ammonium polyphosphate. The most advantage of this product is smallest particle size, which suitable for materials have high requirements on the particle size.
As its smallest particle size, it has high stability and not easy to hydrolyze and will have little effect on the physical properties of the product.
It 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.
For its advantage of high degree polymerization and high heat stability, it has best application in intumescent coating, it works as an essential component in intumescent formulations for thermoplastics.Also in other fields like adhesive tape, cable, glue, sealants, wood, plywood, fiberboard, papers, bamboo fibers, extinguisher. TF201 is also a best option.
Application
1. Used to prepare many kinds of high-efficiency intumescent coating, the flameproof treatment for wood, multistory building, ships, trains, cables, etc.
2. Used as the main flameproof additive for expanding-type flame retardant used in plastic, resin, rubber, etc.
3. Make into powder extinguishing agent to be used in large-area outfire for forest, oil field and coal field, etc.
4. In plastics(PP, PE, etc. ), Polyester, Rubber, and Expandable fireproof coatings.
5. Used for textile coatings.
