The higher the water temperature, the greater the solubility, but it is almost insoluble in organic solvents. PVA solubility varies with the degree of alcoholysis and polymerization. Partially alcoholized and low-polymerized PVA dissolves extremely fast, while fully alcoholyzed and high-polymerized PVA dissolves slowly. The general law, the effect on the solubility of PVA, the degree of alcoholysis is greater than the degree of polymerization. The PVA dissolution process is carried out in stages, that is: affinity wetting-swelling-infinite swelling-dissolution.     Following is our advantage for your reference .  1.quality is soul of an enterprise & culture of our company ,we can offer free samples for quality test before you placing an order. 2.our filament is compatible with all 3d printer brand.Diameter tolerance is +/-0.03MM. 3.Various types of filament with various colors in 1.75mm , 2.85mm , 3mm. 4.Box, Spool label, filament color can be customized according to your requirements. 5.TIME IS GOLD for you and for us.so we have professional production line and stuff whom can making a nice quality in short time.        Regarding packaging;  * Spool+PE vacuum bag+desiccant+sticker+color box+carton box; * 8Rolls/CTN Size:43.5*43.5*16.5mm * 12Rolls/CTN Size:43.5*43.5*24.5mm * Desiccant bag will keep bag moisture-free,so the filament is safety during shipping . * Vacuum sealed bag can reduce moisture absorption with a resealable opening to store left over material.
