The industry’s first technology that transforms end-of-life tire rubber into a functional, fully re-crosslinkable rubber.  This process realigns the critical sulfidic bridge, instead of breaking it, creating a like-new thermoplastic rubber with essentially all the valuable polymers, linkages, and carbon black from the original tire.  This is a first for science, sustainability, and industry. 

WATCH PTR™ IN THE LAB
SUCCEEDING WHERE OTHERS HAVE FAILED.

Until now, the devulcanization process had broken down the integrity of the end-of-life thermoset tire 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.

PRISM™ is:
Phase Recurrent Induced Sulfidic Metathesis

This “First in Class” patented process chemically and physically converts 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 critical sulfidic bridge, a major breakthrough for the rubber industry..

ORIGINAL CRUMB RUBBER
30 MESH Ground Tire Rubber @ 500x

1. Carbon Nano-Clusters
2. Polysulfidic Crosslink
3. Bound Free Molecular Space

When traditionally recycled, the polysulfidic crosslink bonds in crumb rubber are broken or destroyed. This release of sulfur degrades the integrity of the rubber and produces a weaker, less pliable rubber as a result. The more the rubber is broken down, the more bonds are broken. Currently, the process only breaks down the rubber to approximately 200 microns

POST REACTION
Post Reaction Rubber Matrix

1. Polymer Chains Relax
2. The Polysulfidic Bridge
3. Free Molecule Space

After our patented reaction, the Polysulfidic Bridge re-aligns, allowing the polymer chain to relax and substantially increasing the free molecule space. This allows us to take the rubber down to 5-10 microns while keeping the integrity of the rubber intact.

THE RESULT
Re-crosslinked Rubber Matrix

1. Ridged Polysulfidic Crosslink
2. Carbon Nano-Clusters
3. Embedded Polymers
4. Expanded Molecular Space
5. Allows re-entanglement

The newly crosslinked matrix uniformly distributes the nano-carbon, strengthens the sulfidic bridge, and allows for an unprecedented surface area to be utilized. The expanded molecular space allows graft-able polymers in, and the complete re-entanglement with asphalt. The result is new black master batch rubber. An industry first.
