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
The test results in the following table show that ETHANOX™ 330 antioxidant is particularly effective in LDPE plastics for wires and cable applications.
Antioxidant | %wt. | Hours to Failure |
ETHANOX™ 330 | 0.025 | 1368 |
Product A | 0.025 | 1320 |
ETHANOX™ 330 | 0.1 | 4728 |
Product A | 0.1 | 4176 |
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.
Thermal Stability of High-Density Polyethylene (HDPE) in presence of Copper powder at 200°C
The test results in the following table show that ETHANOX™ 330 antioxidant provides excellent stability when used in HDPE wires and cables.
Antioxidant | Hours to Fail at 200°C |
None | 3 |
ETHANOX™ 330 | 41 |
Product A | 35 |
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.

Cable types by voltage
Low Voltage (2 kV and lower)Resins: PVC, PE, PP, and EPDM | Medium Voltage (2 –35 kV)Resins: XLPE and EPDM | High Voltage (35 – 300kV)Resins: XLPE, FEP, and PTFE |
