Injection moldable, water-soluble plastics
Injection moldable, water-soluble plastics
(OP)
Hi,
I've been researching water-soluble plastics, in particular, polyvinyl alcohol pvoh. There were some articles back in 2008-2009 from several companies that claimed they could successfully injection mold it. Does anyone know of suppliers that can currently supply raw pelletized materials, or have experience with injection molding it? Or has the need for this type of material, pardon the pun, dissolved?
My search has come up with the following:
MonoSol (IN, USA) made a product called MonoPol
Environmental Polymers (UK) made a product called 'Depart' but they've since gone out of business. Anyone know if Depart is still being made by anyone?
The application I intend to use it for is to act as a 'lost wax' core in a secondary molding process. The cores would ideally be injection moldadable (for volume).
Any other recommendations for suitable materials or suppliers would be much appreciated.

All I know about PVA is that it dissolves a _lot_ faster in alcohol than in water.
Actual wax is injection moldable. Is that not suitable?

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

I did get in contact with a supplier that produces an injection moldable PVOH - Mowiflex by Kuraray. Plan to run some trials with it. Here's the link for future reference.
