Wiring Duct Material Properties

Rigid Polyvinyl Chloride (PVC)

A general purpose lead-free material for indoor applications. It has a UL 94 ame class of V-0 with a UL recognized continuous-use

temperature up to 50°C (122°F). Used in the manufacture of the following types of Panduit wiring duct and covers: G, F, D, FS, MC, H,

HN, HS, CWD, DRD.

Halogen-Free, Polyphenylene Oxide (PPO)

A special purpose material for use in halogen-free or high-temperature applications. It has a UL 94 ame class of V-0 with a UL

recognized continuous-use temperature up to 95°C (203°F) and is 20% lighter than PVC. Used in the manufacture of the following types

of Panduit wiring duct and covers: NE and NNC.

Low-Smoke, Halogen-Free, Polyphenylene Ether + High Impact Polystyrene (PPE + HIPS)

A special purpose material for use in low-smoke, halogen-free, and high-temperature applications. It has a UL 94 ame class of V-0

with a UL recognized continuous-use temperature up to 105°C (221°F). Meets the regulatory requirements of the mass transit industry

and other applications where re and public safety are critical; such as in trains, buses, offshore oil and gas platforms, and other similar

environments. Used in the manufacture of Type TNC wiring duct and covers.

Polypropylene (PP)

A exible material with a UL 94 ame class of V-2 with a UL recognized continuous-use temperature up to 65°C (149°F). Used in the

manufacture of Type FL exible wiring duct.

Recommended Precaution when using Type NE, NS, NNC, and TNC Wiring Duct

Cleaning solvents and cutting uids that contain any of the following chemical agents should not come into contact with these types of

wiring duct or covers. These chemicals are the most commonly known to cause stress cracking.

• Hydrocarbons

• Phenols

• Ketones
