PVA-S

PVA-S @DF is our specially developed water soluble solution for dual extrusion when you need to print with styrene based materials. PVA-S has an excellent adherence to ABS, ABS-X, ASA-X, GLASSBEND and TPU98A. PVA-S dissolves slightly slower than regular PVA and it is advised to dissolve in luke-warm water, preferably in circulated water. PVA-S can handle higher nozzle temperatures (<250°C) without the risk of cross linking and clogging the nozzle and is therefore perfect for printing with styrene based materials which typically print at higher temperatures.

PVA-S features:

  • Great adhesion to styrene based materials
  • Stable at higher nozzle temperatures (<250°C)
  • Performs in heated environments up to 55-60 °C
  • Good dissolvability in luke warm water
  • Biodegradable when dissolved in water

Packaging:

PVA-S is available in nearly any type of packaging and labelling but will always be supplied in a vacuum bag. Ask our team to help you customizing your product.

Additional info:

PVA-S works with most adhesion techniques used for technical materials, but is best used with specialized 3d printing adhesion sprays or a glue stick.

PVA-S can be used on most Dual printing desktop FDM or FFF technology 3D printers.

Storage:

Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.
