Frequently Asked Questions

SureMix® S6 is formulated to maximize processability for compounds containing carbon black and low-to-medium silica loadings. SureMix® CO2 is formulated to optimize performance and cure characteristics with improved processability in moderate-to-very high silica loadings. SureMix® can be leveraged to reduce mixing time and/or the number of mixing passes.

SureMix® S6 – Processing & Storage Stability

  • Maximize Extrusion Rate and Quality
  • Optimize Processing While Maintaining Performance
  • Both Silica & Carbon Black
  • Maintain Compound Modulus

SureMix® CO2 – High Silica Loading

  • Maximum Wet Traction with the Highest Silica Loadings
  • Lowest Heat Buildup / Rolling Resistance
  • Achieve Fast Cure Rates at High Silica Loadings
  • Enables High-Performance Silanization

We are continually adding applications; currently, the list includes NR, SBR, sSBR, FsSBR, BR, EPDM, NBR, HNBR, and CPE.

Yes, the process and performance characteristics depend on the polymer and filler type. The same reduction in viscosity and improvement in dispersion will be observed with and without silane present.

SureMix® is not a coupling agent; if high-performance silanization procedures are followed, including sulfur correction, silane requirements can be reduced by 30-40%. SureMix® reduces side reactions, which increases the efficiency of silanes.

With SureMix®, manufacturers can reduce undesirable ethanol emissions by 30-40%.

SureMix® overcomes the deficiencies of conventional process aids, which can detrimentally affect cure time (fewer parts produced), modulus (performance & handling), abrasion resistance (product life & treadwear), and hysteresis (durability & fuel economy).
