Choosing between nylon, POM, polycarbonate, and PEEK can be challenging. Each of these engineering plastics offers a unique combination of properties, costs, and processing characteristics.
The Four Major Engineering Plastics at a Glance
| الممتلكات | Nylon (PA6) | بوم (أسيتال) | كمبيوتر شخصي | بيك |
|---|---|---|---|---|
| Strength (MPa) | 70-85 | 60-70 | 55-75 | 90-100 |
| Max Use Temp (°C) | 100 | 100 | 120 | 250 |
| مقاومة المواد الكيميائية | جيد | ممتاز | Poor | Outstanding |
| امتصاص الرطوبة | عالية | منخفضة جداً | منخفضة جداً | منخفضة جداً |
| Relative Cost | $$ | $$$ | $$$ | $$$$$$$$$ |
Nylon: The All-Round Workhorse
Best For: General engineering applications, parts requiring toughness and fatigue resistance, oil/hydrocarbon exposure, cost-sensitive projects.
Watch Out For: Moisture absorption causing dimensional changes, property variation with humidity, acid exposure.
POM (Acetal): The Precision Specialist
Best For: Precision mechanical components (gears, bearings), dimensional stability in varying humidity, low-friction sliding components.
Watch Out For: Limited impact resistance, formaldehyde degradation if overheated, poor adhesion.
Polycarbonate: The Impact Champion
Best For: Optical clarity applications, exceptional impact resistance, electrical enclosures, safety equipment.
Watch Out For: Very poor chemical resistance, environmental stress cracking, UV degradation without stabilizers.
PEEK: The High-Performance Specialist
Best For: Extreme temperatures (up to 250°C), aggressive chemical environments, aerospace and medical implants.
Watch Out For: Extremely high cost (10-20x nylon), high processing temperatures (350-400°C), requires specialized equipment.
