Latest Patents

Papakonstantopoulos holds several significant patents, the latest of which include:

1. **Silica Reinforced Rubber**: This invention is centered on the breakthrough discovery that a specific combination of hydrophobating silanes and sulfur crosslinkable silanes results in outstanding performance characteristics in silica reinforced rubber formulations. Such formulations greatly enhance abrasion characteristics and reduce hysteresis, all while maintaining vital rubber properties. The patent details a sulfur-cured rubber formulation involving essential components such as rubbery polymers, sulfur, silica, and specific amounts of hydrophobating and crosslinkable silanes.

2. **Method for Repairing Self-Sealing Tires**: This innovative technique addresses the replenishment of sealant in self-sealing tires during repairs or recapping. The method aims to restore the tire's original self-sealing capabilities, allowing it to remain functional until a more convenient repair can occur. It involves injecting a liquid sealant formulation into the tire’s sealant layer through puncture holes and sealing those holes in the tire's structure. The patent emphasizes using liquid polyisobutylene as the sealant with specific molecular weight characteristics.
