"PVA is a new interesting print material witch dissolves in water. Is\u00B4s great \r\nto use as a support material when you are printing with a dualextruder printer.&lt;br&gt;\r\n&lt;br&gt;\r\nJust print the support material with PVA on of the extruders and once finished \r\nput the printed object in warm water for a couple of hours and then viola! The \r\nsupport material PVA has disappeared!&lt;br&gt;\r\nPrinter temperature is around 180 - 210 \u00B0C&lt;br&gt;\r\n&lt;br&gt;\r\n0.50 KG of PVA on a spool. Total weight including the plastic spool 0.80kg&lt;br&gt;\r\nComes in a sealed bag with desiccant.&lt;br&gt;\r\n&lt;br&gt;\r\n&lt;b&gt;Storage&lt;/b&gt;&lt;br&gt;\r\nPVA is very sensitive to water and humidity. When not using the material you \r\nshould always store in the sealable bag it comes in together with the Silica \r\nbag.&lt;br&gt;\r\n&lt;br&gt;\r\n&lt;b&gt;PVA&lt;/b&gt;&lt;br&gt;\r\nPolyvinyl alcohol (PVOH, PVA, or PVAL) is a water-soluble synthetic polymer \r\nhydrolysed from polyvinyl acetate.&lt;br&gt;\r\nPVA is fully degradable and is a quick dissolver. PVA has a glass transition \r\ntemperature of around 85\u00B0C (185F), but this temperature depends on the polymer's \r\ndegree of hydrolysation (ratio of alcohol groups to acetate groups)&lt;br&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
