YSPA5063 series is an eco-friendly, high-efficiency Phosphorus-Nitrogen (P-N) based halogen-free flame retardant.
- Key Characteristics: Large particle size, high hydrophobicity, and non-migrating properties.
- Mechanism: It forms an intumescent char layer during combustion, which provides thermal insulation, oxygen barrier, and prevents flame spread.
- Advantages: Non-hydrolyzing, non-precipitating, excellent self-extinguishing char formation, and offers a better cost-performance ratio compared to Bromine-Antimony systems.

Applications
- Target Material: Specifically designed for Polyamide (PA), suitable for both Glass Fiber (GF) reinforced PA and non-reinforced PA.
- Performance: The modified materials exhibit excellent physical and electrical properties.
- Typical Dosage: In PA + 30% Glass Fiber, a dosage of 15% YSPA5063 is typically sufficient to achieve UL94 V-0 (1.6mm).
- Appearance: Injection molded parts are white and do not turn grey.
- Processability: Good processing performance with no strip breakage and no foaming.
Processing Guidelines
- Drying: Nylon (PA) must be dried before processing; moisture content should be less than 0.1%.
- Temperature: Processing temperature should not exceed 350°C.
Packaging & Storage
- Package: Paper-plastic compound bag with inner plastic liner.
- Net Weight: 25 kg per bag.
- Storage: Store in a cool, dry place. Transport as general chemicals.
Important Notes
- Mixing: This product is a carrier-free masterbatch/powder. Low-speed mixing for 20–30 seconds is sufficient for uniform dispersion.
- Additives: Diffusion oil can be added appropriately to prevent layering.
- Warning: DO NOT use white mineral oil or other binders that are not heat-resistant.
- Mixing Speed: Do not use high-speed mixing to avoid stratification of the flame retardant and uneven feeding.
