YS-201G
Supplied byGuangzhou Yinsu Flame Retardant New Material- Last Updated on Sep 15, 2025
YS-201G by Guangzhou Yinsu Flame Retardant New Material is a modified general crystalline type II polyphosphoric acid ammonium solid-phase flame-retardant. It has a non-polar and superhydrophobic surface. It has high polymerization degree and high decomposition temperature. It also has excellent fluidity, hydrophobicity, and low hygroscopicity.
- It is halogens-free and environmentally friendly, with a surface activation index of over 99%.
- It provides good thermal stability, better migration resistance and higher char yield.
- It has a low oil absorption value, better compatibility, no membrane sticking, no blistering, and no color change.
- It is also completely biodegradable into phosphorus, nitrogen, and other compounds.
- YS-201G can be used in fireproof coatings and textile coatings.
- It has a shelf life of 1 year.
