Figure 3 The dropping point and evaporation loss of DPU-B greases4.3 Colloidal stabilityAs shown in Figure 4, the oil separation results (conical sieve method) of DPU-B greases were lessthan 5wt%, which indicated the good colloidal stability of these DPU-B greases. There was a significantcorrelation between oil separation and consistency of these DPU-B greases. Harder greases… Continue reading Materials Australia Magazine September 2021 Volume 54 No 3 by materialsaustralia
