Flame Retardants: Non-Halogenated

Gas phase by releasing phosphorus radicals that quench flame-propagating reactions. Preferred-PC/ABS alloys for electronics housings and automotive parts to meet UL-94 fire safety standards without the use of brominated compounds

Polymer Processing: High-Performance Plasticizer

Plasticizer for cellulose acetate (photographic films) and nitrocellulose. Increases the flexibility and durability of polymers while maintaining transparency and providing inherent fire resistance

Industrial Fluids: Lubricant Additive

Employed as an extreme pressure (EP) additive and anti-wear agent in synthetic lubricants and hydraulic fluids. Organophosphorus structure provides a protective molecular film on metal surfaces under high-stress conditions

Detail 1

Stable under standard temperatures and pressures

Detail 2

Hydrolyzes very slowly in the presence of strong bases or moisture at elevated temperatures

Detail 3

Store in a cool, dry, well-ventilated warehouse (15°C to 30°C)

Detail 4

Keep containers tightly closed to prevent moisture absorption
