Features & Benefits
Balanced Heat Resistance & Durability
With a Heat Deflection Temperature of up to 92°C, ABS ER468 LG Chem maintains structural integrity in warm environments. This makes it ideal for electrical housings and automotive interior parts that face moderate thermal stress.
Superior Flow for Complex Molds
Its high melt flow rate ensures easy filling of intricate and thin-walled molds. This reduces injection pressure, minimizes molded-in stress, and boosts production efficiency, leading to lower part costs and fewer rejects.
High Impact Strength and Stiffness
This material offers excellent toughness and rigidity, as shown by its high Izod impact strength and flexural modulus. It ensures your products can withstand physical impacts and daily use without cracking or deforming.
Use & Applications
- Electrical/Electronic Products: Housings for power adapters, office equipment, console enclosures, and internal components.
- Miscellaneous Goods: Durable consumer goods, appliance parts, automotive interior trim, and functional components requiring a balance of strength and heat resistance.
