Halogen-free Flame Retardant Polyester Chip for Fire-resistant Fiber

Semi-dull or Bright Flame-resistant PET Chip for Fire-resistant Yarn 

Description: Flame retardant polyester chip is obtained by changing the molecular structure of polyester through linking to phosphorus element. The phosphorous compound exhibits excellent self-extinguishing and flame retardant properties. It enjoys the characteristic of high strength, hydrolysis resistance, high-temperature resistance, UV-Resistance, and excellent spinnability. We can produce halogen-free flame retardant polyester chips, with phosphorus content from 5000ppm to 15000ppm.

It is mainly used for the production of fire-resistant fiber. Such fiber is widely applied in the manufacturing of carpets, curtains, home and car decoration, which has special requirements for the flame retardant property.
