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

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

Description: Flame retardant polyester chip is obtained by changing the molecular structure of polyester by 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 6500ppm to 15000ppm. And the Limiting Oxygen Index (LOI) can be more than 32.
Applications:
It is mainly used for the production of fire-resistant fiber. Such fiber is widely applied in the manufacturing of carpets, curtains, and home and car decoration, which has unique requirements for flame retardant properties.
