Natural PVA and high-temp materials

[aag 5]

I have two simple questions:

• I have seen on some vendor sites that UM commercializes both "PVA" and "Natural PVA". "Natural PVA" appears to cost 50% more than "PVA", but I couldn't find any info on whether it offers any advantages. Do you know?
• I need to print some stuff that should be as temperature-stable as possible. I understand that thermoplastics are, by definition, limited in their thermostability. What is the most thermostable material that one can print with an UM S5?

many thanks in advance for any info and thoughts that you might have!

As far as I know there is only one PVA, sometimes called PVA, sometimes called Natural PVA. 

But UM offers two spool sizes, 350g (or 300 ?) and 750g.

I see, but I am sure it is a failure of the shop.

i will then buy quickly the cheap one, before they find out... 🙂

Good idea, it is ca. Eur 88.- which is a good price for 750g of PVA.
