The cross-link density was varied at constant conversion. Thermodynamic and mechanical properties were calculated as a function of the cross-link density. A new relative reactivity volume (RRV) algorithm was developed to generate the cross-linking network by …

Density of Tough Resin in g/ml Jiga
WebDensity is defined as the mass per unit volume of a substance. Water has a density of 1 kg/l at 4°C. When the specific gravity is defined based on water at 4°C, then the specific gravity is equal to the density of the liquid. However, if the specific gravity is expressed at different temperatures, it will no longer be equal to the density. Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or … See more Relative density ($${\displaystyle RD}$$) or specific gravity ($${\displaystyle SG}$$) is a dimensionless quantity, as it is the ratio of either densities or weights The reference material can be indicated using subscripts: See more See Density for a table of the measured densities of water at various temperatures. The density of substances varies with temperature and pressure so that it is necessary to specify the temperatures and pressures at which … See more (Samples may vary, and these figures are approximate.)
