UL 1332 FEP Wire — 200°C / 300V High Temperature Insulation, Horizontal Flame — México
Style 1332 is the FEP-insulated high-temperature wire within UL Subject 758 — engineered for internal wiring of appliances where standard PVC insulation cannot survive the thermal environment. Rated 200°C and 300 Vac with extruded FEP (fluorinated ethylene propylene) insulation at 13 mils minimum average wall thickness, this wire maintains full dielectric and mechanical integrity at temperatures that degrade PVC and even some silicone rubber constructions. Horizontal flame certified, with optional oil-resistant (80°C) and gasoline-resistant builds for chemically aggressive environments.
For Mexican importers and OEM manufacturers supplying commercial kitchen equipment, industrial process machinery, and high-temperature appliance sectors, Style 1332 delivers the combination of alta temperatura performance, chemical resistance, and UL recognition that export markets and domestic NOM-aligned compliance frameworks require.

High-Temperature Applications — Aplicaciones de Alta Temperatura en México
The 200°C rating of Style 1332 opens application categories that are completely outside the range of PVC-insulated wire families. In the Mexican industrial and commercial equipment market, this wire serves the following sectors:
- Commercial cooking and bakery equipment — internal wiring of convection ovens, deck ovens, commercial fryers, and industrial food warmers used across México’s industria alimentaria, where heating element leads and thermostat sensor wires are continuously exposed to radiant and convective heat exceeding 150°C inside the appliance enclosure.
- Industrial process heating equipment — internal leads in heat treatment furnaces, plastic injection molding machines, and industrial dryers manufactured or imported into México’s automotive and plastics processing sectors, where wire insulation integrity at sustained 180–200°C is a non-negotiable specification.
- Lighting fixture internal wiring — high-output luminaire wiring near lamp housings in commercial lighting equipment where FEP’s combination of 200°C thermal rating and excellent UV resistance provides long service life in proximity to high-intensity discharge or halogen light sources.
- Gasoline and oil-exposed environments — with the optional gasoline-resistant and 80°C oil-resistant builds, Style 1332 is suitable for internal wiring in fuel-handling equipment, generator sets, and marine engine accessories imported into México where chemical resistance alongside high temperature performance is required simultaneously.
Engineering Notes — FEP Insulation Properties and Specification Considerations
FEP vs. PVC at elevated temperatures: Standard PVC insulation (Styles 1007, 1015) begins to soften and lose dielectric integrity above 80–105°C. FEP maintains its mechanical and electrical properties continuously at 200°C — a fundamental material difference, not just a rating increment. In enclosures where wire may contact hot metal surfaces or run adjacent to heating elements, FEP’s non-stick surface and dimensional stability under heat prevent insulation deformation and potential short circuit faults that PVC cannot avoid.
Thin insulation wall at 13 mils: Despite the extreme temperature rating, Style 1332 specifies only 13 mils minimum average FEP wall — thinner than Style 1015’s 30-mil PVC wall for the same voltage class at 300V. This reflects FEP’s superior dielectric strength per unit thickness compared to PVC. The thinner wall results in a smaller overall wire diameter, which benefits harness routing in space-constrained high-temperature appliance enclosures — a practical advantage over heavier-walled alternatives like mica-insulated wire.
Optional glass braid covering for mechanical protection: In applications where the wire may be subjected to abrasion against sheet metal edges, oven rack movement, or vibration contact with metal surfaces, the optional glass braid covering (7 mils minimum) over the FEP insulation provides mechanical protection without compromising the 200°C thermal rating. Specify this option explicitly for convection oven and industrial furnace applications where wire routing paths include potential contact points.
Chemical resistance of FEP in gasoline environments: The optional gasoline-resistant rating makes Style 1332 suitable for generator set and fuel handling equipment wiring where aromatic hydrocarbon vapors contact the wire insulation surface. FEP’s chemical inertness to fuels, oils, and most industrial solvents is a significant advantage over silicone rubber (Style 3071, 3135) which, while temperature-rated, has lower resistance to hydrocarbon chemical degradation.
