Ethanox™ 330 for Power Cable Applications
ETHANOX™ 330 is a hindered phenolic antioxidant that is specifically engineered for exceptional protection and long term stability in wire and cable insulations and jacketing applications. Ethanox™ 330 is featured with superior resistance to hydrolysis for use in tough applications and harsh conditions such as power cables and wires.
Why ETHANOX™ 330 is the best antioxidant for wires and cables
Electrically neutral, ETHANOX™ 330, is extremely effective in polyethylene wire insulation which typically requires long-term protection while exposed to copper. See below for heat stability test results for ETHANOX™ 330 in HDPE and LDPE plastics for cable applications:
|Thermal stability of Low-Density Polyethylene (LDPE) in presence of Copper, oven-aged at 105°C|
|Thermal Stability of High-Density Polyethylene (HDPE) in presence of Copper powder at 200°C|
|Antioxidant||%wt.||Hours to Failure|
Samples of low-density polyethylene (LDPE) containing TiO2, oxalic acid bis (benzylidene hydrazide) and a copper deactivator were placed on copper foil and then oven-aged.
The formulation above contained 1% wt. TiO2 pigment and equal amounts of antioxidant and the copper deactivator.
|Antioxidant||Hours to Fail at 200°C|
Samples of high-density polyethylene (HDPE) containing the copper deactivator were placed on copper foil for an accelerated test by Differential Scanning Calorimeter (DSC).
The formulation above contained 0.1% wt. of a copper deactivator, 0.5% wt. antioxidant, and 1% wt. TiO2 pigment.
If you're facing any of these issues in your cables, ETHANOX™ 330 can help!
- Water Treeing: ETHANOX™ 330 is the ideal antioxidant for use in medium voltage XLPE and crosslinked EPDM to overcome water treeing that is typically caused by moisture exposure and electrical stress.
Thermal Stability for Applicances: ETHANOX™ 330 is an excellent choice for 125°C/150°C rating wires and cables that are commonly used in appliances. Due to its high temperature stability, ETHANOX™ 330 is particularly designed to pass the 150°C /3000 hr test that is required for applicance applications.

About Wire and Cable processing and applications:
Wire and cable insulation and jacketing products are manufactured by the extrusion of polyethylene compounds through a crosshead. The molten compound is then transferred onto the bare conductor for insulation or onto the insulated wires for jacketing.
