Acrylonitrile Butadiene Styrene (ABS) and Electrical Enclosures: A Brief Overview
- ABS: Common plastic offering affordability and some strength.
- Limitations: Lower heat resistance and limited electrical insulation.
- Potential Use: Low-voltage applications with minimal heat, or non-electrical purposes within electrical environments.
- Important: Prioritize materials with superior heat resistance and proper electrical insulation for electrical components.
Alternatives: Fiberglass, Polycarbonate, Die-cast Aluminum (better heat resistance & insulation).
Takeaway: While ABS might exist in specific electrical settings, its limitations make it a less suitable choice for plastic electrical enclosures compared to dedicated materials that prioritize safety.

Takeaway: While ABS might sufice for some plastic electrical enclosures its limitations make it a less suitable choice compared to dedicated materials that prioritize safety.
Polycarbonate: A Versatile Choice for Electrical Enclosures
Polycarbonate stands out as a popular material for electrical enclosures, offering a compelling blend of properties that make it suitable for various applications. Here's a closer look:
Strengths:
- High Impact Resistance: Polycarbonate excels at withstanding bumps, impacts, and accidental physical contact, safeguarding internal components.
- Good Heat Resistance: Compared to some plastics, polycarbonate performs well in environments with moderate heat generation from electrical components.
- Natural Clarity: This transparent property makes it ideal for enclosures where visibility of internal components is crucial for monitoring or maintenance purposes.
- Lightweight: Polycarbonate's lower weight makes it a practical choice for enclosures of various sizes, reducing overall weight and potential strain on mounting points.
- Rust-Free: As a non-metallic, non-ferrous material, plastic cannot rust, also, Polycarbonate provides resistance to many chemicals.
Applications in Electrical Enclosures:
- Control Panels and Monitoring Systems: The transparent nature allows for easy visual inspection of internal components and wiring.
Considerations:
- Limited Performance in Extreme Heat: While suitable for moderate heat, polycarbonate can deform or melt at very high temperatures (>275 F). This makes it unsuitable for applications with excessive heat generation.
- Size Matters: Although Fibox offers the largest non-metallic polycarbonate enclosure on the market. Today's injection molding can only push the polycarbonate so far. When looking for very large enclosures 36x36 and up, metal or fiberglass are required.
Conclusion:
Polycarbonate emerges as a versatile and cost-effective choice for a variety of plastic electrical enclosure applications.
