FAQ

What's the difference between general-purpose and plating-grade ABS?
Plating-grade ABS like LG Chem HI-121H has enhanced surface quality, lower stress levels, and better adhesion properties for electroplating. It typically costs 15-20% more but delivers superior chrome finish quality with minimal defects.
How do I prevent yellowing in ABS parts?
Use UV-stabilized grades like Trinseo Magnum 3453 for outdoor exposure, maintain proper processing temperatures below 260°C, ensure thorough drying, and avoid contamination with PVC or other chlorinated materials that accelerate degradation.
Can I blend different ABS grades to optimize cost and performance?
Yes, but maintain similar melt flow rates within 20% and test thoroughly. Blending a premium grade like BASF Terluran with Formosa 709 can reduce costs while maintaining adequate performance for many applications.
What processing parameters work best for thin-wall ABS molding?
Use high-flow grades (MFI >20), increase injection speed and pressure, maintain mold temperatures at 60-80°C, and ensure melt temperature stays between 240-260°C. Gate size is critical - typically 0.7-1.0x wall thickness.
How does ABS compare to PC/ABS blends for automotive applications?
Pure ABS offers better processability and lower cost, while PC/ABS provides higher heat resistance (up to 110°C vs 80°C) and improved impact at low temperatures. Choose based on your specific temperature and impact requirements.
