Product Overview
Kingfa MAC-601 is a high-performance PC/ABS alloy specifically engineered for injection molding applications that require a perfect marriage of fluid processability and rugged toughness.
With an unnotched Izod rating of "No Break," this material is designed to withstand significant physical stress, while its superior melt flow allows for the effortless filling of complex, thin-walled geometries. It is the ideal choice for manufacturers seeking a smooth, high-quality surface finish without sacrificing the structural integrity of the final part.
Core Advantages
Superior Flowability: Optimized for fast cycle times and the filling of intricate, thin-wall mold designs.
Extreme Impact Toughness: Achieves a "No Break" performance under unnotched Izod testing, ensuring high durability for handheld and portable devices.
Aesthetic Excellence: Delivers a smooth, high-gloss surface appearance suitable for consumer-facing electronics and automotive interiors.
Thermal Stability: Maintains a high heat deflection temperature (DTUL) of 116 °C, providing reliability in heat-sensitive environments.
Reliable Insulation: Exceptional dielectric strength and volume resistivity for safe use in power tools and communication equipment.
