The automotive industry’s shift toward more aerodynamic and visually cohesive exteriors is placing new demands on material science. Shanghai KUMHO-SUNNY is leading this evolution with its high-flow modified ASA, which is increasingly selected for its ability to produce large-scale, “class-A” surfaces. Unlike traditional ABS, which degrades under UV light, these modified ASA variants remain stable and vibrant throughout the vehicle’s lifespan.
Based in Shanghai, KUMHO-SUNNY produces 350,000 metric tons of specialized polymers annually, serving as a critical link in the global automotive supply chain. The company’s “integrated innovation” approach allows them to combine raw material synthesis with rapid application testing. This ensures that their materials meet the rigorous standards of both luxury and mid-range vehicle manufacturers.
The ability to produce complex parts like spoilers and decorative trim without a secondary painting process is a major advantage of KUMHO-SUNNY’s resins. This is made possible by lowering the melt viscosity without sacrificing the toughness of the acrylate rubber. The result is a material that flows into complex undercuts and thin walls while maintaining a perfect surface finish, free of flow marks or “silvering.”
The environmental and financial benefits of this “non-painting” approach are substantial, with cost savings reaching up to 30%. By eliminating the VOCs associated with paint lines, manufacturers can significantly reduce their environmental footprint. This synergy of performance and sustainability is why KUMHO-SUNNY is a preferred supplier for modern automotive components.
As the industry moves toward more sophisticated designs, KUMHO-SUNNY continues to push the boundaries of what is possible with modified plastics. Their high-heat resistant and dimensionally stable ASA variants are also finding applications in the smart home market. By providing the engineering community with technical data and innovative materials, they are paving the way for the future of industrial design.
