Product Name: TC-1301 – Rubber Treatment


Proprietary Rubber Adhesive of 100% solids


Treat rubber crumb for compatibility with SBR, NR and EPDM rubber compounds. The base formula is designed for use with #34 to infinity mesh crumb. Works with tire crumb and other recycled rubbers.

Typical Usage

Apply TC-1301 at a ratio of 5 pounds to 95 pounds of crumb.

Treated crumb is then added to SBR, NR, EPDM compounds, generally at a ratio of 30%-50% treated crumb, as a direct replacement for that portion of the compounds. Ratio may be up to 70%-100% for some uses.

If 15/20 mesh crumb is being used, TC-1301 may need to be increased to 5.5 pounds to 94.5 pounds crumb. If crumb is contaminated with high portion of fabric, ratio may need to be modified further.

If 60 mesh crumb is being used, ratio may drop to 4.5 pounds to 95.5 pounds crumb, to maintain tensile and duro for end product requirement.

Compatible Host Compounds

  • Black color
  • Durometer from 65-75
  • NR, SBR, or EPDM base, blends can be very good
  • Compounds that need or are able to process at higher viscosity levels.



Black. Other colors may be available for some compounds.


Bagged in low-melt bags sized for your Banbury batch size.

Benefits with TC-1301 Treated Crumb

  • Allows crumb to be part of the compound rather than just filler, which generally is a small percentage.
  • Cure time decrease
  • Viscosity increase
  • Resilience increase
  • Modulus increase
  • When using high percentages of crumb, the physical size of one pound of rubber compound is greater than without crumb.
  • May be able to recycle your waste rubber with TC-1301 for re-use


Drawbacks with TC-1301 Treated Crumb

  • Viscosity increase
  • Green strength decrease
  • Elongation decrease
  • Smoothness and tack decrease with higher percentages
  • Scorch time slight decrease (depends on compound)



  • TC-1301 is best distributed with the action of Banbury mixers
  • TC-1301 can be premixed with the crumb or mixed with the compound and crumb in your Banbury. The required order of loading is to add compound, crumb, and then TC-1301. Over 300ºF can damage the crumb and TC-1301
  • If you provide 5 pounds of your compound, we will do the testing for the proper amount of TC-1301
  • EPDM requires NorthStar Elastomers to test your compound with TC-1301 for proper ratios. We will need your desired tensiles, duro and modulus.
