Web28 de mar. de 2024 · PPC has a slow hydration process due to which heat generation is comparatively lower. Cost. OPC is more costlier than PPC. The price of PPC is less which makes the construction economic. Permeability and Fineness. Lower the fineness , higher the permeability. OPC has a fineness of 225m 2 /kg. WebOne determinant of OPC density could be the necessity to generate OLs. Consistently, OPC density is low in CNS regions where unmyelinated axons predominate such as the molecular layer of the cerebellar cortex (Givogri et al., 2002; Sun et al., 2024). However, in other regions the distribution of OPCs does not match that of OLs.
