ABS LG Yongxing FR‑500
ABS LG Yongxing FR‑500
Product Introduction ABS LG Yongxing FR‑500 is a high‑flow ABS resin with UL94 V‑0 flame‑retardant rating, suitable for applications requiring flame‑retardant performance.
Main Applications
Electronics & Electrical Appliances: This is the primary application field for FR‑500. It is widely used for housings and internal structural parts of home appliances such as televisions, washing machines, refrigerators and air conditioners, as well as various electronic‑electrical accessories. Its flame‑retardant property is critical for electrical‑safety protection.
Automotive Components: Used for certain automotive interior parts requiring flame retardancy, such as instrument panels and air‑conditioning ducts.
Sports Goods: Suitable for manufacturing selected sports equipment.
Other Industrial Fields: Applied for general‑industrial‑purpose components.
Material Properties
| Item | Details |
|---|---|
| Material Type | Flame‑retardant (UL94 V‑0), high‑flow injection‑molding grade ABS |
| Key Applications | Electronic‑electrical components, automotive interior parts, sports goods |
| Processing Method | Injection molding |
| Salient Features | High flowability, flame retardancy, well‑balanced mechanical performance |
| Key Molding Notes | Sufficient drying required; control barrel and mold temperature; avoid excessive temperature to prevent material degradation |
Injection‑Molding Parameters
| Process Parameter | Reference Range | Remarks & Instructions |
|---|---|---|
| Drying Treatment | 80°C, 2‑4 hours | Keep hopper heated to prevent re‑moisture absorption; ensure moisture content below 0.1%. |
| Barrel Temperature | Rear zone:180‑200℃ Middle zone:190‑210℃ Front zone:200‑220℃ Nozzle:200‑230℃ (do not exceed 240°C to avoid material degradation) |
‑ |
| Mold Temperature | 40‑80℃ (commonly 50‑60℃) | Higher mold temperature improves surface gloss and reduces internal stress. |
| Injection Pressure | Adjust according to flow length and part structure | May be properly reduced for high‑flow grades. |
| Holding Pressure | Approx. 30%‑60% of injection pressure | Optimize per wall thickness and structure to reduce internal stress and shrinkage. |
| Injection Speed | Medium or medium‑high speed | High‑speed improves gloss yet may cause flow marks; adopt slow‑to‑fast profile for high‑appearance requirements. |
| Screw Speed | Proper speed for uniform plasticization (e.g. 50‑80 rpm) | ‑ |
| Back Pressure | 0.5‑1.0 MPa | Facilitates uniform plasticization and degassing. |
