Achieving a deep “piano black” high-gloss finish traditionally required a plastic part to be molded and then sent to a paint line. Shanghai KUMHO-SUNNY is changing this with its high-flow modified ASA, which allows this premium effect to be achieved directly out of the mold. This not only reduces production costs by 20% to 30% but also eliminates the environmental impact associated with secondary painting processes.
As a leading China-based modified ASA supplier, KUMHO-SUNNY produces 350,000 metric tons annually, focusing on “integrated innovation.” This allows them to combine raw material synthesis with rapid application testing to optimize the molecular architecture of their resins. The result is a material that maintains surface tension and color depth while offering the weather resistance needed for automotive exteriors and outdoor telecommunications.
The high-flow characteristics of their modified ASA are critical for “mold-in-color” technology. If the resin does not flow evenly, the pigments will not orient correctly, leading to visible defects like silvering. KUMHO-SUNNY’s expertise in rheological properties ensures a superior finish in high-complexity molds. Their weather-resistant XC811 series is a prime example of a material that maintains its integrity long after standard resins would have degraded.
In the automotive sector, the move toward large-scale parts with complex undercuts has made high-flow variants essential. These materials allow for the production of aerodynamic and aesthetically cohesive exteriors without the need for VOC-heavy paint lines. This reduction in the carbon footprint of manufacturing facilities makes modified ASA a central component of modern industrial design.
KUMHO-SUNNY continues to solve the “impossible” requests of designers by focusing on specific properties like haptic quality and high heat resistance. Their technical blogs and design guidelines provide the engineering community with the data needed to push the boundaries of plastic achievement. As industries transition toward sustainable models, the role of high-performance materials like modified ASA will be more critical than ever.
