pvc has high hardness and mechanical properties. the mechanical properties enhance with the molecular weight increasing but decrease with the temperature increasing. the mechanical properties of rigid pvc (upvc) are very good; the elastic modulus can reach 1500-3,000 mpa. the soft pvc (flexible pvc) elastic is .

an elastic modulus is a number that measures an object or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it. the elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: a stiffer material will have a higher elastic .

when plasticisers are added, pvc shows rubber-like elasticity with high tensile strength and fatigue strength, and can be used for industrial hoses, gaskets, automobile parts, and . in other words, the tensile modulus is an index showing the magnitude of elongation, when a test piece is pulled apart. it is the .

young's modulus - tensile modulus or modulus of elasticity - for steel, glass, wood and other common materials.it is used to describe the elastic properties of objects like wires, rods or columns when they are stretched or compressed. tensile modulus is defined as the . chlorinated pvc (cpvc), 2.9. chromium, 36.

young's modulus, numerical constant, named for the 18th-century english physician and physicist thomas young, that describes the elastic properties of a solid undergoing tension or compression in only one direction, as in the case of a metal rod that after being stretched or compressed lengthwise returns to its original .

elastic properties of pvc pipes - researchgate the other material properties re- quired to completely describe the physical nature of pvc are the yield strength cry, yield strain ey, percentage elongation at yield, initial modulus e , and the poisson's ratio v. this paper reports the laboratory tests conducted on pvc pipes at the university of houston to evaluate the elastic.
