Technical Examples

The present invention provides a method of increasing the absorption rate of peroxides into polymer particles used to fabricate electrical cable insulation. The method includes contacting the polymer particles with a peroxide compound and an additive under physical mixing conditions at a temperature that is above the melting point of the peroxide compound but below the softening point of the polymer particles for a period of time sufficient to allow he peroxide compound to absorb into the polymer particles. Preferably, the additive is squalane or another branched, hydrocarbon oil that substantially increases the rate at which the peroxide compound is absorbed into the polymer particles and improves the peroxide cure.
