ABS vs PP 塑料:哪种材料最适合您的防护箱?(2026)
材料详细对比:ABS(丙烯腈-丁二烯-苯乙烯)vs PP(聚丙烯)防护箱。冲击强度、温度范围、UV 抗性、耐化学性、成本和理想使用场景。
| Property | ABS | PP (Polypropylene) |
|---|---|---|
| Impact Strength | High (Izod 200-400 J/m) | Medium (Izod 50-150 J/m) |
| Tensile Strength | 40-50 MPa | 25-35 MPa |
| Temperature Range | -20 to +80 C | -20 to +100 C |
| Low-Temp Performance | Becomes brittle below -20 C | Stays flexible to -30 C |
| UV Resistance | Moderate (with UV stabilizer) | Good (with UV stabilizer) |
| Chemical Resistance | Moderate (avoid ketones, esters) | Excellent (resists most acids, bases, solvents) |
| Surface Finish | Glossy, paintable | Slightly textured, less paintable |
| Recyclability | Yes (recycling code 7) | Yes (recycling code 5) |
| Tooling Cost | $8,000-25,000 | $5,000-15,000 |
| Cycle Time | 30-90 sec | 45-120 sec |
| Cost per Case | $20-150 | $15-100 |
| Best For | Industrial, impact-heavy, polished look | Marine, chemical, cold weather, low-cost |
| Common Brands | Pelican Storm, SKB, Gator | Pelican Air, большинство китайских |
结论
选择 ABS:冲击密集型应用、精美外观、品牌箱。选择 PP:海事、化学暴露、低温环境、成本敏感的 OEM。许多客信新材料防护箱主体使用 PP(化学+低温),锁扣和铰链使用 ABS(冲击+外观)。
