Do your enclosure compounds support wireless signal transmission?

Yes, all of Aurora's thermoplastic enclosure compounds are inherently RF-transparent, allowing Wi-Fi, Bluetooth, cellular (4G/5G), RFID, and other wireless signals to pass through without attenuation. This is a critical advantage over metal enclosures for IoT devices, wireless access points, smart meters, 5G small cells, and any enclosure housing wireless communication equipment. No signal holes, external antennas, or RF windows are required.

Are recyclable compounds available for enclosure manufacturing?

Yes, Aurora offers multiple recyclable options for enclosure applications. AuroraGuard PC/ABS is available in recyclable grade series. AuroraGuard PC compounds can be provided with recyclable PC content. AuroraShield ASA includes recyclable and environmentally friendly products. All compounds are RoHS compliant, and REACH-compliant options are available for global market access.

How can I request a quote for enclosure-grade compounds?

Contact Aurora's sales team directly through the website, call (330) 422-0700, or reach out to a regional sales representative. Provide details about the enclosure type, required NEMA/IP rating, flame retardancy requirements (UL 94 grade), indoor or outdoor use, chemical exposure environment, color requirements, and production volumes. The technical team will recommend the optimal compound and provide competitive pricing.

Impact-Resistant, Flame-Retardant, NEMA-Ready Compounds for Enclosures and Housings

Q: What are the best thermoplastic compounds for electrical enclosures?

The best compound depends on the specific enclosure requirements. For maximum impact resistance, AuroraGuard PC (polycarbonate) is the industry standard with outstanding toughness and low-temperature performance. For balanced impact, aesthetics, and cost, AuroraGuard PC/ABS alloys deliver excellent dimensional stability with flame-retardant options. For outdoor UV exposure, AuroraShield PC/ASA provides superior weatherability. For chemical-resistant applications, AuroraTec PC/PBT and AuroraGuard PBT excel. Aurora's technical team can help select the optimal compound for the NEMA rating, environment, and performance requirements.

Q: What compounds work best for outdoor enclosures?

AuroraShield PC/ASA compounds are specifically engineered for outdoor enclosures, combining polycarbonate impact strength with ASA's superior UV and moisture resistance. ASA offers outstanding dark color weatherability and stress crack resistance. AuroraGuard PC with UV-stabilized grades also performs well outdoors. Both materials maintain structural integrity, NEMA ratings, and appearance across years of outdoor exposure. UV-stabilized formulations pass OEM accelerated weathering and two-year outdoor weathering tests.

Why Compound Selection Is Crucial for Enclosure Manufacturing

These compounds provide UL 94 V0 flame retardancy, NEMA 4X weather protection, outstanding impact strength, superior dimensional stability & excellent colorability for enclosures serving electrical, electronic, industrial, commercial, telecommunications & outdoor applications.

Enclosure compound selection determines product certification eligibility, impact performance, flame safety, environmental protection ratings, aesthetic quality, and service life. Each enclosure application has unique requirements for impact resistance, temperature range, chemical exposure, UV stability, and ingress protection. Choosing the wrong compound risks failed UL/NEMA testing, field failures, warranty exposure, and lost customer confidence.

Impact & NEMA Performance: Enclosure compounds must deliver the impact, crush, and ingress protection required for specific NEMA ratings. NEMA 4X demands resistance to corrosion, windblown dust, rain, splashing water, and hose-directed water. Higher ratings like NEMA 6P require submersion resistance
Flame Safety: UL 508A industrial control panel enclosures and UL 94 V0 flame ratings require self-extinguishing compounds that prevent electrical faults from causing external fires. Non-halogenated options are increasingly specified for indoor applications
UV & Outdoor Durability: Outdoor enclosures face continuous UV exposure that degrades standard plastics within years. UV-stabilized PC, PC/ASA, and ASA compounds maintain structural integrity and appearance across decade-long outdoor service
Material Selection Complexity: PC offers the highest impact but has limited chemical resistance. ABS provides cost-effective toughness. PC/ABS balances both. PBT delivers chemical resistance. PC/ASA adds weatherability. Understanding these tradeoffs is essential for optimal enclosure performance
RF Transparency: Unlike metal enclosures, thermoplastic compounds are transparent to Wi-Fi, Bluetooth, RFID, cellular, and other wireless signals, critical for IoT devices, wireless access points, and smart infrastructure enclosures

Our AuroraGuard™, AuroraTec™, and AuroraShield™ product families include PC (polycarbonate), PC/ABS, ABS, MABS, PBT, PC/PBT, PC/PET, PC/ASA, ASA, PEI, and TPU composites.

What are the best thermoplastic compounds for electrical enclosures?

The best compound depends on your specific enclosure requirements. For maximum impact resistance, AuroraGuard™ PC (polycarbonate) is the industry standard with outstanding toughness and low-temperature performance. For balanced impact, aesthetics, and cost, AuroraGuard™ PC/ABS alloys deliver excellent dimensional stability with flame-retardant options. For outdoor UV exposure, AuroraShield™ PC/ASA provides superior weatherability. For chemical-resistant applications, AuroraTec™ PC/PBT and AuroraGuard™ PBT excel. Our technical team can help select the optimal compound for your NEMA rating, environment, and performance requirements.

What compounds meet UL 508A and NEMA 4X requirements?

Aurora’s materials are formulated specifically for UL 508A and NEMA-rated enclosures. AuroraGuard™ PC and PC/ABS alloys with UL 94 V0 flame-retardant grades provide the flame, impact, and environmental protection required for UL 508A industrial control panel enclosures. For NEMA 4X, UV-stabilized PC and PC/ASA compounds deliver the corrosion resistance, weatherability, and ingress protection these demanding ratings require. Our on-site UL certification testing laboratory supports faster material qualification.

How do plastic enclosures compare to metal enclosures?

Thermoplastic enclosures offer significant advantages over metal: 50–70% lighter weight, complete corrosion immunity (no rust, oxidation, or galvanic issues), inherent electrical insulation, RF transparency for wireless applications, superior design flexibility through injection molding, lower tooling costs for complex geometries, zero painting or coating requirements, and excellent colorability. Metal enclosures maintain advantages where extreme impact resistance is required or where the enclosure must serve as an EMI shield or grounding conductor.

What compounds work best for outdoor enclosures?

AuroraShield™ PC/ASA compounds are specifically engineered for outdoor enclosures, combining polycarbonate impact strength with ASA’s superior UV and moisture resistance. ASA offers outstanding dark color weatherability and stress crack resistance. AuroraGuard™ PC with UV-stabilized grades also performs well outdoors. Both materials maintain structural integrity, NEMA ratings, and appearance across years of outdoor exposure. UV-stabilized formulations pass OEM accelerated weathering and two-year outdoor weathering tests.

What is the difference between PC, ABS, and PC/ABS for enclosures?

PC (polycarbonate) offers the highest impact strength and heat resistance with excellent clarity for transparent covers, but has limited chemical resistance and higher cost. ABS provides good impact resistance at lower cost with excellent surface finish, but lower heat resistance. PC/ABS alloys combine PC’s impact performance with ABS’s processability and surface aesthetics at a moderate price point, making it the most popular enclosure compound. Aurora offers all three with flame-retardant, glass-filled, UV-stabilized, and recyclable-content options.
