1. ABS: high fluidity, cheap, suitable for components that do not require high strength (components that are not directly impacted, and do not withstand structural durability in reliability tests), such as internal support frames (keyboard brackets, LCD brackets) )Wait. There are also commonly used on electroplated components (such as buttons, side keys, navigation keys, electroplated decorative parts, etc.). At present, Chimei PA-757, PA-777D, etc. are commonly used.
2. PC+ABS: Good liquidity, good strength and moderate price. It is suitable for parts with high rigidity and high impact toughness, such as frames, shells, etc. Common material code: Bayer T85, T65.
3. PC: High strength, expensive, and poor liquidity. It is suitable for shells, buttons, transmission frames, lenses, etc. that require high strength. Common material codes such as: Teijin L1250Y, PC2405, PC2605.
4. POM has high stiffness and hardness, excellent fatigue resistance and wear resistance, small creep and water absorption, good dimensional stability and chemical stability, good insulation, etc. Commonly used in pulleys, transmission gears, worm gears, worms, transmission parts, etc., commonly used material code such as: M90-44.
5. PA is tough and absorbent, but becomes fragile when the water evaporates completely. Commonly used in gears, pulleys, etc. For key gears that are subject to greater impact, fillers need to be added. Material code such as: CM3003G-30.
6. PMMA has excellent light transmittance. After 240 hours of accelerated aging, it can still transmit 92% of sunlight, 89% of the outdoor ten years, and 78.5% of ultraviolet rays. High mechanical strength, certain cold resistance, corrosion resistance, good insulation performance, stable size, easy to form, relatively brittle, often used for transparent structural parts with certain strength requirements, such as lenses, remote control windows, light guides, etc. Commonly used material code such as: Mitsubishi VH001.
