Executive summary:

A cylinder of degassed material was prepared for density measurements using an Anton Paar DMA 512 P Density measuring cell. The pressure of the sample was measured using a Heise 3000 psia pressure transducer. Densities at several pressures were measured at various temperatures. At 20.0°C the density was 1.5575 g/cc.

Remarks on result:

other: Calculated from regression equation

The densities were recorded at a range of temperatures between -31 °C and 20 °C. The regression equation is d[g/cm3] = 1.614 - 3.018E-03 * T (°C) - 1.189E-05 * T² (°C²). Mean deviation from the polynomial regression equation is ± 0.14%. The precision is with high probability > 99%.

Conclusions:

The density of PPVE at 20 °C is 1.55 g/cm³.

Executive summary:

The density of PPVE was recorded at a range of temperatures between -31 °C and 20 °C. By polynomial regression, the density at 20 °C is 1.55 g/cm³. The study was not compliant with GLP. Few details were available but the method description indicates that a hydrostatic balance method was likely used. The hydrostatic balance method is set forth in OECD 109. Therefore the study is considered reliable with restrictions.

Description of key information

The density of PPVE is 1.5575 g/cm3 at 20.0 °C.

Additional information

In the key study, a cylinder of degassed material was prepared for density measurements using an Anton Paar measuring cell. Densities at several pressures were measured at various temperatures. The study was not conducted under GLP and therefore is considered reliable with restrictions. In the supporting study, a density of 1.55 g/cm3 at 20 °C was reported. Few details were available but the method description indicates that a hydrostatic balance method was likely used. The hydrostatic balance method is set forth in OECD 109. Therefore the study is considered reliable with restrictions.
