TF-201 Ammonium polyphosphate flame retardant APPII for Rubber
Introduction
Ammonium polyphosphate flame retardant APPII offers significant core advantages as a flame retardant in rubber.
Firstly, APPII exhibits excellent thermal stability, enabling it to withstand high temperatures without degradation.
Secondly, it forms a protective char layer on the surface of the rubber, effectively preventing further combustion and slowing down the spread of flames.
Moreover, APPII releases very low levels of smoke and toxic gases when exposed to fire, mitigating the potential health hazards.
Overall, APP II enhances the fire resistance of rubber materials, making them safer in various applications.
Characteristics
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.
