The PC/ABS alloy material combines the dual advantages of polycarbonate (PC) and acrylonitrile butadiene styrene copolymer (ABS).

1. High strength and stiffness balance: PC's high impact resistance and ABS's rigidity combine to effectively absorb shock from daily drops and impacts, protecting internal precision components from damage.

2. High Temperature Resistance and Flame Retardancy: Combining the high-temperature resistance of PC with the easy processability of ABS, the material maintains structural stability even in high-temperature environments. Furthermore, by adding flame retardants, PC/ABS can achieve a V0 flame retardant rating, significantly reducing the risk of fire caused by battery short circuits.

3. Antistatic and Abrasion Resistance: By incorporating functional additives, the surface antistatic performance of the PC/ABS shell is enhanced, reducing dust adhesion; its abrasion resistance also surpasses that of traditional plastics, making it less prone to scratches during long-term use.

II. Processing Efficiency and Design Freedom

1. Molding process adaptability: PC/ABS materials have excellent fluidity, enabling efficient production of intricate curved surfaces and thin-walled structures with precision molding, meeting the requirements of earphone shells for dimensional accuracy and lightweight design.

2. Surface treatment simplification: Materials support no-paint processes, achieving high gloss or matte textures through direct dyeing with masterbatch, reducing secondary processing steps, lowering costs, and enhancing environmental friendliness.

III. Safety and Durability Upgrades

PC/ABS has good chemical stability against sweat, oils, and greases, and can maintain its integrity even in prolonged exposure to sweat and oils.

2. Weather Resistance Optimization: Some modified PC/ABS materials can resist fading and brittleness caused by long-term exposure to UV rays by adding UV stabilizers, thereby extending the product's service life.

IV. Environmental Protection and Cost Efficiency

1. Recyclable: Supports recycling of plastics，aligning with the trend of green manufacturing. 2. Recyclable plastics support recycling.

2. Outstanding cost-performance ratio: Compared to pure PC materials, PC/ABS offers lower costs while ensuring performance, making it suitable for the large-scale production needs of mid to high-end Bluetooth earphones.

Grafa produces PC/ABS alloy materials that combine the excellent properties of both materials, featuring high impact resistance, high strength, heat resistance, and low shrinkage rate. With its "tough yet flexible" characteristics, it offers a solution that balances safety, aesthetics, and production efficiency for the外壳 of Bluetooth headsets. (Note: The last part about "外壳 of Bluetooth headsets" seems to be in Chinese. The correct English translation for "外壳" is "shell," so the final sentence should ideally be "With its 'tough yet flexible' characteristics, it offers a solution that balances safety, aesthetics, and production efficiency for the shell of Bluetooth headsets.")
