Specific GravityDensity and specific gravity sound quite similar, some even say that they are synonyms; however, they are actually not the same, below we are going to introduce the differences of them.What's the meaning of "Density"?Density ismass or weight of a substance per unit volumeundernormal temperature and pressure. WebSpecific gravity is the ratio of the density of a substance to the density of the same volume of water. Any reliance you place on such information is therefore strictly at your ownrisk.

Polyvinyl chlorideis the world's third-most widely produced syntheticplasticpolymer. From here density and SG are calculated using the following formulas: Specific Gravity = (Weight A / Weight B)Density = (Weight A / Weight B) * 0.9976 g/cm3 , where 0.9976 g/cm3 is equal to the density of distilled water at 23C. 0000125208 00000 n Cookies are only used in the browser to improve user experience. For PS the melt density is 0.945 g/cm 3 and for PP it is about 0.74 g/cm 3.
