Effects of Guayule in Tank Track Pads
Abstract
In this report the effects of Guayule rubber in tank track pads are discussed. The two Guayule compounds evaluated were versions of the triblend in which the natural rubber and the Styrene Butadine rubber (SBR) were replaced with Guayule in separate formulations. The formulations used and the physical data obtained from each are included in this report. The only Guayule that was used was extracted by Toluene and Methanol, and Xylene and Methanol. These two lots were blended together in equal ratios to form the two experimental batches mentioned previously. After the mixing was completed, these batches were extruded by means of a cold feed Extruder that was fed by a mill. The extrusions were in the form of T-142 (M60) and T-157 (M2-M3) pads. Seventy-five pads each were cured of T-142 and T-157 for each of the three compounds. The T-142 pads were cured 70 minutes at 300 F and the T-157 pads were all cured 45 minutes at 310 F. No significant problems were encountered in curing these parts. After curing, parts were tested for adhesion to the metal inserts. This adhesion testing evidenced no adhesion failure.
