VII. Frequently Asked Questions (FAQ)

Q: Can it plasticize well at 210°C in twin-screw extrusion?
A: Yes. After being encapsulated in a carrier to form the masterbatch, the flame retardant's melting point decreases, allowing easy melting with glass-filled PA6 and lowering the overall plasticizing temperature. It plasticizes very well at 210°C, and the maximum processing temperature can be up to 230°C.

Q: For PA6 with 30% glass fiber, what addition level is needed for UL94 V-0? What about for passing 850°C Glow-Wire?
A: For PA6 + 30% GF, add 20% to achieve V-0 at 3.2mm thickness. Add 22% to achieve V-0 at 1.6mm thickness and simultaneously pass the 850°C Glow-Wire test.

Q: For pure PA6 resin, what addition level is needed for UL94 V-0 and to pass 850°C Glow-Wire?
A: For pure PA6 resin, add 24% to achieve V-0 at 1.6mm thickness and pass the 850°C Glow-Wire test.

Q: What is the most important precaution when using this masterbatch?
A: The heat resistance of any flame retardant is limited. For this masterbatch in PA6 GF materials, key points are: 1) Processing temperature: keep twin-screw temp ≤ 230°C; 2) Rotation speed: keep twin-screw speed ≤ 300 rpm. This yields products with color closest to natural, best properties, and lowest cost. Also, keep injection molding temperature ≤ 255°C.

Q: For direct injection molding with PA6 GF material, what drying temperature is recommended for the masterbatch?
A: It's recommended to mix the masterbatch with the base resin uniformly and then dry at 90°C for 3 hours. Higher temperatures may cause the carrier to become sticky, leading to agglomeration or even discoloration.

Special Note:
The optimal addition ratio varies depending on the base material. Small-scale trials are essential before full production.
