XW-M150 is a novel flame retardants for PET fibers based on ionic liquids. It’s supplied as masterbatch of a concentration of 10% FR. First, the FR exhibits excellent compatibility with PET polymers, enabling uniform dispersion within the polymer matrix without compromising smoothness of the fiber spinning. Therefore, it has addressed the key challenges associated with traditional solid flame retardants, which adversely affect fiber spinning. Second, it demonstrates superior flame retardant performance. At a dosage level of 0.5%, the limited oxygen index (LOI) increases to over 30%. And flame doesn’t drip during vertical burning. Finally, XW-M150 improves the processability of PET fiber, lowering processing temperatures, and consequently reducing thermal degradation of the polymer.

1. Materials:

PET：YuanFang CH610-2 (Viscosity: 1.0 dL/g)

Flame retardant masterbatch：Inovia XW-M150

2. Processing condition：

Drying: 140℃ for 6-8 hours;

Pre-treatment: Add 5 to 15% of XW-M150 (with a flame retardant content of 10%) to the base material and mix evenly before spinning.

The fiber was spanned at a third-party institute. Before spinning, the flame-retardant masterbatch was evenly mixed with the resin material. The extrusion temperature of the flame-retardant fiber was 5~15 ℃ lower than that of the blank resin material.
