Additional Recommendations

Peroxide Curing Systems: We generally recommend HPS 11, TR 141, WB 16, WB 42, WB 212, WB 222 and WS 280.

Dosage: We recommend 2% of total batch weight as a starting point.

Building Tack: For Butyl and Halobutyl we recommend 40 MS or Strukrez 110.

Friction Reduction/Slip: TR 121 is recommended for most polymers; TR 131 is suggested as an alternative. TR 141 is for any peroxide cured polymer.
