EVR's proprietary rubber compound offers:


  • Blends directly with virgin rubber at very high levels (30%-50%).
    Current global crumb rubber recycling methods and technology produces products that cannot be blended at any significant level. Because the crumb produced by other companies cannot form a significant number of new bonds when it is vulcanized a second time, use of more than perhaps 5% max causes the tire rubber to lose strength and wear resistance.
  • Reduces the customer cost by 10-40% (Dry Cost and Manufacturing Cost)
  • Also our products lower scrap in injection molding compounds. EVR fills the cavity completely thus lower scrap.
  • Provides superior performance in tires as measured by:
    • Superior wear properties: 12-20% more miles/tire.
    • Reduced rolling resistance in tires.
    • Reductions in heat gain on large truck tires.
    • Improved traction and wet-skid resistance.

Value — serious cost advantages

Dependent on the recipe, there is a dry cost savings associated with using EVR. In addition to a dry cost savings, there is a manufacturing cost savings associated with the use of EVR. This cost savings will come into play because of the unique usage of EVR.

The EVR product is introduced into the “final” pass of the compound recipe. It is treated as just another raw material in the recipe. The weight of the master batch used in each final batch will be reduced by the same percentage as the percentage of EVR going into the final pass. This master batch weight reduction will be done automatically by using a recipe calculated in “pphr” and using the same banbury mixer fill factor. No manual reduction calculations would need to be made. Simply put, if there is a usage of 20% EVR in the final pass, there will be a 20% reduced need of master batch to complete the compound order.

A typical truckload order of 40,000lbs would need approximately 37,800lbs of master batch mixed to meet that order requirement. The remaining weight would be made up of raw materials that go into the final pass to complete the recipe. Since the EVR goes into the final pass, the need for master batch would be reduced. This reduction in mixed master batch translates into fewer batches of master batch needing to be mixed. Since custom mixers use a processing time on the mixer to add a “manufacturing” cost to the total cost of the compound, fewer batches mixed means a lower cost total manufacturing cost. The calculated comparison chart above shows some examples of how EVR could affect mixer processing time.
