Higher performance, lower cost for your formulations

Rubber compounds containing Harmonite have demonstrated better abrasion resistance, and equal or better hardness, tensile, elongation and volume properties after immersion and heat aging tests – all while reducing formulation costs. Harmonite is compatible with a number of important elastomeric synthetic rubber monomers and block co-polymers:
• SBS and APP modified bitumen • EPDM rubber formulas • Nitrile rubber formulas • SBR/BR rubber blends.

Certified research study suggests Harmonite’s ability to simultaneously increase plant throughput/capacity utilization and lower operating costs.

  • Harmonite Reduces Mixing Time & Power Consumption

Harmonite can be an economical replacement for Gilsonite®, Petroleum Pitch, Carbon Black and other expensive additives.

Harmonite Formulas Reduce Mixing Time & Power Consumption

Control Formulation Mixing Time Added Operating Capacity
Power Consumption
Power Savings
EPDM
23-50% shorter
460 – 1,000 hrs/yr
20-36% lower
$15 – 27K/yr savings
Nitrile
21-28% shorter
420 – 560 hrs/yr
25-30% lower
$16 – 19K/yr savings
SBR/BR blend
10-17% shorter
200 – 340 hrs/yr
10-25% lower
$6 – 16K/yr savings

*Based on 2,000 hours/per year operation. Increased capacity based on batch mixing time only. Energy savings based on $.05/KW-hr.

  • Shorter mix time and lower power consumption indicates that Harmonite may be acting as a compatibilizing agent that improves homogenization and/or dispersion of materials.
  • Harmonite had a plasticizing effect on all three control formulas

  • Harmonite® vs. Gilsonite®

Harmonite® vs. Gilsonite®

  • Organic Phase is chemically similar, yet different.
  • Both exhibit good compatibility with elastomers including butyl rubber, styrene-butadiene-styrene, styrene-isoprene-styrene, and others — but at a fraction of the cost, Harmonite delivers more bang for the buck!

  • Harmonite has a plasticizing effect in rubber compounds — it works as a processing aid with the potential to reduce consumption of more expensive plasticizers as well as other ingredients and fillers.
  • Shorter mix time and lower power consumption indicates that Harmonite may be acting as a compatibilizing agent that improves homogenization and/or material dispersion.
  • Harmonite has demonstrated improved natural waterproofing characteristics that make it an ideal additive for rubber-based membranes and sealers.

Just one pound of Harmonite Plus has 979 ft2 of surface area — that, and it's asphaltene chemical properties, gives Harmonite superior binding properties.

That's roughly the surface area of 5,000 baseballs!
