WebApr 29, 2024 · PC-ABS is a blend of both PC and ABS, while ABS is a blend of acrylonitrile (a polymer), butadiene (a rubber), and styrene (a polymer). PC-ABS does not have the weaknesses of ABS, mainly the heat intolerance. It is also generally stronger and easier to machine than ABS and provides higher impact resistance. WebMolecular doping of conjugated polymers with a lower stiffness can have an adverse effect on the elastic modulus ().Poly(3-octylthiophene) (P3OT) and poly(3-dodecylthiophene) (P3DDT) prepared by oxidative polymerization feature a low regio-regularity of only 75% and hence a low modulus of 60 and 50 MPa at room temperature, 9,11 presumably due to a …

WebNov 30, 2024 · To put it simply, the Young's modulus is related to the compression distance α, and the instantaneous stiffness S. Eq. 2 is less sensitive to the usual measurement errors in the absolute values of α and P and can also show the changes in modulus brought about by increasing compressive strain. This is especially significant for polymer spheres, … WebSep 4, 2024 · Tensile tests were carried out on these microparticle-modified epoxy polymers to measure the Young's modulus.
