Purity (HPLC): ≥ 99.0%
Melting point: 137-139 ℃
Phosphorus content: 18.0 ± 0.5%
Acid value: 326 ± 4mgKOH/g
Iron content: ≤ 0.005%
Chloride: ≤ 0.01%
Water content: ≤ 0.5%
Packaging: 25kg cardboard barrel or woven bag lined with plastic bag (or according to customer requirements)
Characteristics: soluble in water, stable at room temperature
Application: This product is an environment-friendly flame retardant. It is a new generation of permanent flame retardant modified product launched according to the structural characteristics of polyester. Compared with CEPPA, it has the characteristics of high phosphorus content, low relative addition, and better thermal stability. The flame retardant chips produced by CEPPA have a higher melting point than the flame retardant chips produced by CEPPA, which can reach 256 ℃. It is not easy to produce floating filament breakage during spinning, and can spin out finer polyester products. It is widely used in flame retardant fields such as textile flame retardant, spinning flame retardant, chemical fiber flame retardant, various clothing materials, decorative cloth, etc.
