ProFlame ® PN4131C Specially for PA66 + Glass fibre
ProFlame-PN4131C is formulated flame retardant based on organic phosphorus component. It is suited for
both GF-reinforced and unreinforced PA66 system. We specially design columned granule appearance, this
will be helpful to reduce dust ,and make material easy to dispersing and feeding.
Product benefits:
1. High flame retardant efficiency, 12.5% dosage can reach 1.6mm V-0 in PA66 with 30% fiberglass
2. Less gas, less mold corrosion
3. Good machinability, no mold scale
4. Flame retardant polyamide compounds show very good physical properties and excellent electrical
properties, CTI >600V

Processing instruction:
1. Pre-drying the polyamide,the moisture content should be below 0.1 % (by wt.).
2. The temperature of the polymer melt should not exceed 350 °C.
3. It is most suitable for equipment with weak shear force.
4. The processing temperature of Parallel twin-screw extruder should keep between 240 ~ 260 ℃ with
vacuum at the same time.The temperature is too high, the physical property loss of PA66 is large, and the
yellowing is also large.
5. Do not use low-alkali or high-alkali fiberglass. High-quality non-alkali fiberglass is preferred.
