Abstract
A process for forming a vulcanized elastomer composition. An alternating electric field is applied to a first composition comprising vulcanized crosslinked elastomer particles while the composition is compressed to thereby devulcanize the crosslinked elastomer particles and form a second composition comprising devulcanized elastomer particles A crosslinking agent is added to the second composition comprising the devulcanized elastomer particles. The second composition having the crosslinking agent is then vulcanized to form the vulcanized elastomer composition.
Claims13
A process for forming a vulcanized elastomer composition, comprising:
- applying an alternating electric field to a first composition comprising vulcanized crosslinked elastomer particles while said composition is compressed, said alternating electric field having a frequency and a voltage sufficient to devulcanize said crosslinked elastomer particles to form a second composition comprising devulcanized elastomer particles having substantially the same surface and interior properties;
- adding a crosslinking agent to said second composition comprising said devulcanized elastomer particles;
- and
- vulcanizing said second composition having said crosslinking agent to form said vulcanized elastomer composition.
