UL AWM Style 10362 — PFA Fluoropolymer Wire for High-Temperature Protected Internal Wiring
UL AWM Style 10362 uses extruded PFA (Perfluoroalkoxy) fluoropolymer insulation, rated at 250°C maximum and 600 Vac, covering a conductor range from 30 AWG to 4/0 AWG. The Style is covered under UL Subject 758, Section 1, and is designated for internal wiring. CableApex supplies UL AWM Style 10362 PFA wire from factory production. UL AWM documentation and order-specific construction details can be confirmed before quotation.
PFA is a melt-processable fluoropolymer with thermal and chemical resistance properties comparable to PTFE, while being produced through conventional extrusion processes. For enclosed equipment wiring where 250°C maximum temperature rating and fluoropolymer chemical resistance are required, UL 10362 PFA is typically more cost-efficient than UL 1659 PTFE, depending on construction, AWG, order volume, and processing requirements.

Cost comparisons between fluoropolymer Styles depend on construction, AWG, order volume, and market conditions. The relative positions shown above reflect general production economics rather than fixed ratios. Confirm pricing at the quotation stage based on the specific ordered construction.
Applications — Protected Internal Equipment Wiring
UL AWM Style 10362 is designated for internal wiring. Constructions under this Style are typically evaluated for enclosed equipment wiring applications where PFA insulation, 250°C maximum temperature rating, and fluoropolymer insulation properties are required by the equipment design.
Equipment categories in which UL AWM Style 10362 constructions are commonly evaluated for protected internal wiring include high-temperature industrial processing equipment, enclosed analytical and measurement instrumentation, semiconductor fabrication equipment internal wiring exposed to process environments, and industrial control equipment requiring 250°C rated internal wiring within enclosed assemblies. In each case, the equipment-level evaluation by the applicable certification body determines whether the specific UL AWM 10362 construction is acceptable for that installation.
UL AWM Style 10362 is not designated for field wiring, building wiring, utility distribution, external cabling, or any use outside protected internal equipment wiring without a specific equipment-level acceptability determination.
Engineering Notes for Procurement Buyers
- PFA vs PTFE for 250°C internal wiring — construction and cost considerations: UL 10362 PFA and UL 1659 PTFE share the same temperature ceiling (250°C maximum) and voltage rating (600 Vac), but differ in wall thickness profile for smaller AWG sizes. UL 10362 specifies 10 mils minimum average wall for 30–10 AWG, while UL 1659 specifies 20 mils for 26–10 AWG. For fine-wire constructions, PFA offers a thinner wall option at equivalent temperature class. PFA is generally more cost-efficient than PTFE due to melt-extrusion production economics, though actual pricing depends on the ordered construction, AWG, and order volume. Confirm the cost position at the quotation stage.
- PFA vs FEP for 200°C vs 250°C applications: Where the equipment-level thermal design requires 250°C maximum rated internal wiring, UL 10362 PFA is the fluoropolymer alternative within the Ansheng production scope. For applications where 200°C maximum is sufficient, UL 1332 FEP (300 Vac, 30–10 AWG) is available at a lower cost position. The voltage ceiling also differs — UL 1332 is rated to 300 Vac while UL 10362 is rated to 600 Vac — so equipment voltage requirements should be confirmed before selecting between the two Styles.
- Wall thickness increases with AWG size — confirm construction before specifying: UL AWM Style 10362 insulation wall thickness is class-dependent: 10 mils minimum average for 30–10 AWG; 30 mils minimum average for 9–2 AWG; 45 mils minimum average for 1–4/0 AWG. Equipment designers should account for the significantly thicker wall in the larger AWG range when planning routing and connector compatibility. Final outer diameter depends on the conductor AWG, stranding, and the wall thickness of the specific ordered construction.
