Fluids / Propylene glycol, 60 % by volume

Dynamic viscosity of propylene glycol, 60 % by volume vs temperature

A 60 % by volume propylene glycol solution, freeze protection to about −51 °C — the deepest worthwhile charge, and viscosity is now the design constraint.

Dynamic viscosity in mPa·s, from -35 to 100 °C. The chart and the table below are the same numbers; the table is the one you can copy.

Rows marked published land exactly on a source anchor and are the tabulated figure. The rest are this library’s interpolation between the two anchors either side — good enough to design with, and said out loud so you can decide that for yourself.
