1. White powder. Soluble in water or capable of swelling. Insoluble in lubricants, grease, and most organic solvents. It is hygroscopic. Does not melt when heated; undergoes dehydration and decomposition at around 150°C, turning yellow.
2. PVA degrades slowly at 100°C and rapidly degrades at 200°C. It exhibits light stability. It degrades in strong acids, and softens or dissolves in weak acids or alkalis. Mixture may be formed. The degree of polymerization and alcoholysis are the two main factors determining its physical properties.
3. It is used as a dispersant and protective colloid in vinyl chloride polymerization. It can also be used in the production of polyvinyl formal and vinylon fibers. It is mainly used as an adhesive for metals, rubber, leather, binding adhesive, and fabric sizing agent.

Pva degrades slowly at 100℃ and rapidly at 200℃. Polyvinyl alcohol is light stable. Degrades in strong acids, softens or dissolves in weak acids and bases. Contact with strong oxidants can cause combustion and explosion. can form mixtures. The degree of polymerization and alcoholysis are the two main factors that determine its physical properties.

It's good for my purposes, which are admittedly niche. Honestly overkill for something I'll make a batch of once every 6 months and use 5% of the bag making. Consider using some sort of emulsifier if you try this.

I purchased this to make 3D printer heated bed goo. It was difficult to dissolve in distilled water. It also doesn’t come in a nice plastic container, it comes in a clear baggy which could break open.

It's going pretty well so far. I need to come up with the perfect thickness so I can peel it all in one go, but so far so good!

Came in a plastic bag inside of a box. Would have preferred it came in a bottle, but I will be transerring to smaller bottles anyway. However, if I had needed to store it, the bag would have been inconvenient.

We have done ALOT of research to making slime. Reading about the proper ways to make the PVA solution and borax solution. However, making one small batch of slime with this PVA powder resulted in a very tacky hard slime that has very little elasticity, and broke easy. We had very similar results whether using one tablespoon of borax (to .5 cup PVA solution) or 1 teaspoon borax to .5 c of PVA solution. If you want the soft , stretchy, squishy (not sticky!) slime, then this PVA will not work.

a lot stronger that I suspected. It didn't work with my project. Needed to throw away. Kinda disappointed

Works great for slime. This will make 2.5L of 4% PVA solution. This makes a BUNCH of slime. You will also need a 4% solution of sodium tetraborate (borax). Mix the PVA and borax solution at ≈ 200:15. Stir like the devil and you get special effects grade slime. Add food coloring, glitter, powdered mica, highlighter fluid or whatever to make the look you need.
