Triazine Carbon-forming Agent / Acrylic Coating Flame Retardant - CFA
I. Product Introduction
The CFA series is categorized as a macromolecular triazine carbon-forming agent and is commonly used in conjunction with ammonium polyphosphate (APP) flame retardant for polypropylene (PP) applications. In comparison to traditional APP charring agents, compounded versions of the CFA series offer numerous cost benefits, including lower pricing and reduced dosage, as well as superior properties such as improved anti-precipitation, anti-aging, and heat resistance.
II. CFA-1 Carbon-forming Agent
Primarily used for the production of high-end ammonium polyphosphate (APP) system flame retardants, CFA-1 offers distinct advantages over traditional APP systems. By incorporating CFA-1 in combination with APP, the resulting flame retardant requires less material dosage, yet can still achieve a V0 (1.6mm) rating. In addition to its reduced addition requirement, CFA-1 also provides notable improvements in precipitation resistance, heat resistance, and aging resistance compared to conventional APP systems.
Recommended compounding addition: CFA-1 35%, APP 65%
Flame retardant material reference formula V0(1.6mm):
Material | PP 085 Powder | PP M09 | APP+CFA-1 | PTFE | Antioxidant 215 | Lubricant PETS |
Addition | 50% | 25% | 25% | 0.2% | 0.3% | 0.2% |
Wollastonite can be added by itself, and up to 10% can be added without affecting flame retardancy.
III. CFA-7 Carbon-forming agent
Designed for the production of high-end and economically-efficient ammonium polyphosphate (APP) flame retardants, CFA-7 offers notable advantages over traditional APP systems. When combined with APP, the resulting flame retardant exhibits exceptional stability and boasts a low material cost.
While CFA-7 may have slightly lower heat resistance when compared to CFA-1, it presents an effective alternative if certain mold requirements are met. Specifically, if a customer's mold is suitable, CFA-7 can serve as a complete replacement for CFA-1 and further reduce the cost of the flame retardant within the product.
Recommended compounding ratio: CFA-7 35%, APP 65%
Flame retardant material reference formula V0 (1.6mm):
Material | PP M09 | APP+ CFA-1 | PTFE | Antioxidant 215 | Lubricant PETS |
Addition | 74% | 26% | 0.2% | 0.3% | 0.2% |
Wollastonite can be added by itself, and up to 10% can be added without affecting flame retardancy.
IV. Common Do’s
To prevent yellowing and black spots during extrusion or injection molding when using CFA series products mixed with APP, it's essential to note the following key points:
1. Use PETS instead of EBS as a lubricant.
2. The base material's melting index should be greater than 10.
3. Incorporating a portion of PP powder as the base material can ensure more uniform flame retardant blanking.
4. During extrusion or injection molding, avoid adding a screen, use weak screw shear, and opt for vacuum exhaust when possible.
5. It's best to avoid adding back materials such as nozzle during the extrusion or injection molding process.
6. The recommended addition amount for natural color products is typically 25% to 26%, while for black products, it should be 1 to 2 more which may result in some wastage.
