Abstract
Disclosed herein are tires with a component comprising a cured rubber composition having a high dielectric constant, tire bead fillers comprising a cured rubber composition having a high dielectric constant, and related methods for increasing the dielectric constant of a cured rubber composition for a tire component. According to certain embodiments, the cured rubber composition has a dielectric constant of at least 20 and comprises 100 phr of at least one conjugated diene monomer-containing elastomer, filler comprising at least 25 phr of reinforcing carbon black, a cure package of specified composition, and optionally at least one anti-reversion agent.
Claims20
A tire containing a bead filler comprising a cured rubber composition and an electronic communication module including a radio device having at least a portion of its outer surface surrounded by a second rubber composition, wherein the cured rubber composition comprises:
- a. 100 phr of at least one conjugated diene monomer-containing elastomer,
- b. filler comprising at least 25 phr of reinforcing carbon black;
- c. a cure package comprising
- i. at least 10 phr of vulcanizing agent;
- and
- ii. at least one vulcanizing accelerator, and
- d. optionally at least one anti-reversion agent,
- wherein the cured rubber composition has a dielectric constant of at least 20.
A tire containing a bead filler comprising a cured rubber composition having an increased crosslink density (as compared to a control composition) and a dielectric constant of at least 20.
