Q: Why does PVB resin with a viscosity of 13-15s dissolve faster than a viscosity of 5s?
A: The solubility of PVB resin is related to the molecular weight of PVB itself, and the dissolution temperature, and the dissolution rate is related to the PVB bulk density, that is, the PVB particle type. For example, PVB with the same molecular weight has a bulk density of 2.4 that is more soluble than 1.6.
