Vinidex provides information on material properties to allow engineers and designers to correctly specify a product for a given application.
Material properties include physical properties such as density and molecular weight, electrical and thermal properties and mechanical properties. Mechanical properties, which are commonly measured using standard tests, describe the reaction of a material to an applied load and include properties such as strength, ductility, impact strength and toughness.
Material properties can be constant or can depend on one or more variables. Plastics materials are viscoelastic and have mechanical properties that are dependent on both loading time and temperature. Therefore, plastics pipes, which require long service lives, are designed on the basis of their long term rather than their short term mechanical properties.
