Why Compound Selection Is Critical for Electrical Raceways

Our rigid PVC raceway compounds demonstrate resistance to electrical failure far surpassing metal raceways under similar conditions of heat exposure due to their lower thermal conductivity.

Designed for the extrusion process with a wide processing window, these compounds are available in pellet or powder form with an extensive color range for residential, commercial, institutional, and industrial raceway applications. AuroraGuard™ ABS and PC/ABS compounds complement the portfolio with high-impact solutions for raceway fittings, covers, and accessory components.

Raceway compound selection directly impacts product listing eligibility, flame performance, snap-fit functionality, aesthetic quality, and long-term durability. The compound must meet UL 5A flame, impact, and crush requirements while maintaining the tight dimensional tolerances essential for snap-on cover retention and professional-grade installations. The wrong formulation can result in UL listing failures, warped profiles, loose covers, and premature degradation that damages manufacturer reputation and end-user confidence.

Frequently Asked Questions

What PVC compounds are used to manufacture electrical raceways?

Electrical raceways are manufactured from rigid PVC compounds that meet UL 5A requirements for nonmetallic raceways and fittings, including UL 94 V0 flame performance, impact resistance, and crush resistance testing. Aurora’s AuroraTec™ rigid PVC compounds are UL recognized for electric raceways and are formulated specifically for raceway profile extrusion in both pellet and powder form. For raceway fittings and covers requiring enhanced impact performance, AuroraGuard™ ABS compounds are also available.

What is UL 5A and how does it apply to raceway manufacturing?

UL 5A is the Underwriters Laboratories standard covering nonmetallic raceways and fittings for use as surface wiring systems. It specifies requirements for flame performance (specimens must self-extinguish within 5 seconds), impact resistance, crush resistance, UV stability, and dimensional tolerances. UL 5A listing is referenced by the NEC for nonmetallic raceway installations. Aurora’s AuroraTec™ compounds are UL recognized for electric raceways, supporting manufacturers in achieving UL 5A product listings.

What is the difference between a raceway and a conduit?

While both are enclosed wiring methods, they serve different purposes. Conduit (NEC Article 352) is round, tube-shaped PVC used for concealed or exposed wiring runs. Raceways are typically rectangular or shaped profiles used for surface-mounted wire management. Surface nonmetallic raceways (NEC Article 388) feature snap-on covers for accessible wiring, while wireways (NEC Article 378) provide hinged or removable covers for accessible splicing. Aurora compounds serve both conduit and raceway manufacturing with UL-recognized rigid PVC formulations.

How does PVC raceway compare to metal raceway?

PVC raceways offer several advantages over metal: inherent non-conductivity eliminating ground fault hazards, complete corrosion immunity (no rust, oxidation, or galvanic issues), self-extinguishing flame performance, lighter weight for easier installation, no painting or coating required, and superior appearance retention over time. PVC does not dent, deform, or lose paint like metal versions. Metal raceways provide advantages where extreme impact resistance is required or where the raceway must serve as an equipment grounding conductor.

Can your raceway compounds support multi-compartment profiles?ground conduit?

Yes, AuroraTec™ rigid PVC compounds are formulated with wide processing windows specifically designed for the extrusion process, supporting simple single-channel through complex multi-compartment raceway profiles. NEC requires separate compartments when power/lighting and control/signaling/communications wiring share the same raceway, and our compounds maintain consistent wall thickness, partition integrity, and snap-fit tolerances across all compartments.
