As part of a validation of the properties of an elastomer compound for commercial tire treads, Phoenix asked a recognized American laboratory, ACE in Akron Ohio, to produce elastomer mixes using 30 PHR of “SAR”.
The recipe supplied, which uses standard products recognized for the manufacturing of tire treads, was developed by Phoenix to determine the effects on the compound’s properties of using “SAR” from commercial tire tread crumb rubbers.
As this recipe was under development, it was not optimized.
This project is named “Tread to Tread” in reference to the endless use of crumb rubbers, retreading commercial tires into new treads.
Sample preparation methodology,
Three identical mixes were made by ACE in an in-house laboratory blender (Banbury) as per the recipe supplied by Phoenix (TRTG 8530-C1).
Once the mixes were made, full analyses were carried out.
Laboratory results,
The processability (MDR) and ASTM D2240, D412, D5963 and D1149 measurements and their mean standard deviations being convincing, it was decided to produce three compound mixes based on the TRTG 8530-C1 recipe in industrial production with 30 PHR of “SAR”, i.e. 610 kg of elastomer compounds.
