SUCCEEDING WHERE OTHERS HAVE FAILED.

Until now, the devulcanization process had broken down the integrity of the ELT original thermoset rubber to such a point that the physical properties could not be used during recycling. PRISM™ technology now takes that rubber, at an atomic level, to a reusable thermoplastic rubber with significant industrial applications and improved properties. That’s what happens when every atom counts.

The Industry Standard

  • Thermoset rubber is taken from ELT‘s and traditionally broken down or simply shredded into crumb rubber.
  • When thermoset rubber is recycled, the polysulfidic bonds are broken and sulfur is liberated, removed or rendered inert. This results in weaker, virtually less resilient thermoplastic rubber. The more the rubber is broken down, the more polysulfidic bonds are negatively modified.
  • Currently, the industry has only been able to achieve a reduction of particle size of approximately 150 mesh. There  has been no ambient temperature cost effective method to reduce the particle size to below a 30 mesh.

The Industry Shift

  • PRISM™’s “First in Class” patent(s)-pending process chemically and physically converts ELT thermoset rubber into a re-crosslinkable thermoplastic rubber product while leaving essentially all the valuable polymers, linkages, and carbon black intact. Most importantly the process interrupts, without destroying, the sulfidic bridge, a major breakthrough for the rubber industry.
  • The re-aligned bonds strengthen the sulfidic bridge and allow unprecedented surface area to be utilized. We can now break recycled rubber down to a surface area of 5-10 microns (which is smaller than a red blood cell), creating a thermoplastic PTR™, ready to be re-crosslinked into new rubber-based products for the first time. PRISM™’s PTR™ can be used in roads, roofs, tires and industrial applications.

Limited use ELT rubber now becomes usable, highly functional, and extremely valuable.
