ETHANOX™ 330 Antioxidant for Wires & Cables

Ethanox™ 330 for Power Cable Applications

 
Power cables account for three-quarters of the global wires and cables market. The fast-growing industry demands quality solutions and high-performance additives to help you differentiate your products from competition such as superior endurance and weathering resistance.

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:

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.

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.

ETHANOX™ 330 Applications


ETHANOX™ 330 is typically recommended at 1 - 2 wt% for W&C formulations.

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.
