Flame retardant masterbatch for polyester filament yarns
1. Inert phosphorus-containing flame retardant with high melting point and high phosphorus content, excellent spinnability performance, especially fine denier and ultra-fine denier spinning.
2. inert flame retardant structure, can be uniformly dispersed, for the development of high-strength flame retardant polyester industrial yarn, strength to meet 7.5-8.0cN/dtex.
3. High softening temperature, non-stick, good processability, meet the requirements of online addition spinning.
4. The LOI of the masterbatch added 8% sample is 29.8%, 10% sample is 33.3% and 12% sample is 35.0%.
