ABS vs PC for Outdoor Enclosures | Comparison
A three-dimensional comparison of weatherability, impact resistance, and cost to help you choose right
ABS and PC are the two most common candidates for outdoor equipment enclosures. But their performance characteristics differ significantly — choosing the wrong material can lead to cracking, fading, or even functional failure. This article provides an in-depth comparison of ABS vs PC in real outdoor application scenarios.
ABS — The Affordable All-Rounder
PC — The High-Performance Protection Expert
Quick Comparison
| Property | ABS — The Affordable All-Rounder | PC — The High-Performance Protection Expert |
|---|---|---|
| Impact Resistance | Medium (Izod 15-25 kJ/m²) | Very High (Izod 60-80 kJ/m²) |
| Weatherability | Poor — severe yellowing after 6 months outdoors | Good — 5-10 years with UV stabilizers |
| Transparency | Translucent (light transmission ~85%) | High Transparency (light transmission ≥88%) |
| HDT (1.82 MPa) | 85-95°C | 125-135°C |
| Cost | Lower (~$1.7-2.5/kg) | Higher (~$2.5-4.0/kg) |
| Processing Difficulty | Easy — wide processing window | Difficult — requires desiccant drying, moisture <0.02% |
Recommendation
Recommendation: Choose ABS for indoor or sheltered outdoor applications with budget constraints. Choose PC for direct sun/rain exposure or when high transparency and impact resistance are critical. Note: PC MUST use a desiccant dryer — moisture above 0.02% causes silver streaks and bubbles.
Conclusion
There's no absolute winner — only the right fit. ABS wins on cost and ease of processing; PC dominates in weatherability and impact resistance. Jinsu supplies both premium ABS and PC grades. Need material selection advice? Contact our engineers for a free formulation consultation.
