PVA-S is a 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, PETG 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 or materials which typically print at higher temperatures.

PVA-S features:

• Great adhesion to styrene based materials
• Stable at higher nozzle temperatures <250c
• Dissolves better in luke warm water
• Biodegradable once dissolved in water
• Performs in heated environments up to 55-60 °C
