Additional amount (%) Abrasion (mg)
0 120
0.5 100
1 85
1.5 70

Experimental results show that the addition of DMAEE has decreased significantlyThe wear amount of material is lowered and the wear resistance is significantly improved.

5.4 Comprehensive Performance Evaluation

By comparing the experimental data, the following conclusions can be drawn:

  • Outstanding amount: 1% DMAEE can achieve a good balance between flexibility and wear resistance.
  • Comprehensive Performance Improvement: After adding DMAEE, the comprehensive performance of the sole material is significantly better than that of the unadded control group.
