Effect of ABS Content on Thermal Stability, Tensile Strength, Friction, and Wear of PMMA/ABS BlendsPages 220-228
Nay Win Khun Abstract:
The effect of ABS content on the thermal stability, tensile strength, and wear resistance of polymethyl-methacrylate (PMMA)/acrylonitrile-butadiene-styrene (ABS) (PMMA/ABS) blends was systematically investigated. The thermal stability of the PMMA/ABS blends became higher with higher ABS content due to the increased fraction of higher thermal resistant ABS componen in the blends. However, the increased ABS content in the PMMA/ABS blends from 10 to 70 wt.% resulted in a 17.9% decrease in their tensile strength while the wear volume of the PMMA/ABS blend with 70 wt.% ABS content was 39.5 times larger than that of the one with 10 wt.% ABS content. The PMMA/ABS blend with 10wt.% ABS content had the highest tensile strength and wear resistance among the samples used in this study because of its best miscibility and processability. It could be concluded that the ABS content had a significant effect on the thermal stability, tensile strength, and wear resistance of the PMMA/ABS blends. Keywords: PMMA/ABS blend, ABS content, Thermal stability, Tensile strength, Wear resistance.
