TECHNICAL DATA SHEET
Product Name: T 608 – TireCycle®
Classification
Proprietary 100% solids rubber adhesive
Applications
TireCycle® (treated rubber crumb) is added to SBR, NR, EPDM or other rubber compounds. 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.
Typical Usage
Add TireCycle® to SBR, NR, EPDM 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.
Compatible Host Compounds
- Black
- 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.
Benefits With TireCycle®
- 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
- Cure time 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 pound of rubber compound is greater than without crumb
- May be able to recycle your waste rubber into TireCycle® for reuse
Drawbacks With TireCycle®
- Viscosity increase
- Green strength decrease
- Elongation decrease
- Smoothness and tack decrease with higher percentages
- Scorch time slight decrease (depends on compound)
Mixing
TireCycle® can be mixed with your compound in your Banbury. The required order of loading is to add compound, then TireCycle®. Over 300ºF can damage the crumb.
EPDM requires NorthStar Elastomers to test your compound with our T-608 EPDM for proper ratios. We will need your desired tensiles, duro, and modulus.
Color
Black. Other colors may be available for some compounds.
Packaging
Bagged in low-melt bags sized for your Banbury batch.
Available in 2,000 pound bags for bulk use.
