Tirecycle® T 608

1 of 3 products in this brand
Tirecycle® T 608 is an advanced material based on rubber crumb. It is added to SBR, NR, EPDM or other rubber compounds to enhance both their performance and our environment. The basic formulation uses #34 to infinity mesh crumb. We can formulate it with 60/80 mesh crumb, 15/20 mesh, or other mesh sizes.

End Uses: Solvent Free (100% Solids) Adhesive

Compatible Substrates & Surfaces: Elastomers & Rubbers

Features: Excellent Adhesion, Faster Cure Time, Good Compatibility, High Viscosity

Features & Benefits

Benefits
  • Lower cost
  • Allows crumb to be part of the compound rather than just filler (which generally is a small percentage)
  • Improve pavement adhesion and mileage in tires
  • Hysteresis (Tan Delta) decrease
  • Cure time decrease
  • Die swell decrease
  • Viscosity increase
  • Resilience increase
  • Modulus increase
  • Compression set decreases at room temperature (other temps should be tested)
  • When using high percentages of crumb, the physical size of one lb of rubber compound is greater than without crumb.
  • May recycle your waste rubber in Tirecycle™ for re-use
Drawbacks
  • Some benefits may be detriments in certain uses
  • Green strength decrease
  • Elongation decrease
  • Smoothness and tack decrease with higher percentages
  • Scorch time slight decrease (depends on compound)

Applications & Uses

Compatible Substrates & Surfaces
Products
  • Tires - car, truck, forklift
  • Shoe soles
  • Hose - garden, etc
  • Mats, Grommets, Polypropylene molds
Typical Usage

Add Tirecycle™ to SBR, NR, EPDM or Polypropylene compounds, generally at ratio of 30-50% Tirecycle™, as a direct replacement for that portion of the compounds. Tirecycle™ portion may be up to 75-100% for some uses.

Mixing

Tirecycle™ can be mixed with your compound in your Banbury. The required order of loading is to add compound then Tirecycle™. Over 300° F can damage the crumb.
EPDM requires NorthStar Elastomers test your compound without T 608 EPDM for proper ratios. We will need your desired tensiles, duro and modulus.

Technical Details & Test Data

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, like those used for compression mold-transfer or injection molding are best when body fed into cavity.
