Mitsubishi PVA Polyvinyl Alcohol, Filament
Categories:	Polymer; 3D Printing/Additive Manufacturing Polymer
Material Notes:	PVA filament is quickly soluble in water, bonds well to plastics, and prints easily. Therefore, it is an excellent supporting material for dual extruder 3D printing. This polyvinyl alcohol-based filament is nontoxic, and biodegradable once dissolved in water. PVA is also available in colors and has a high tensile strength for applications other then supporting material. Features: Excellent water solubility Easy to print at low temperature Good bonding to various plastics such as PLA Biodegradable when dissolved in water Limited smell Colors: PVA is available from stock in its natural color. For specific applications, PVA is available in colors on request Information provided by Mitsubishi Chemical.
