When making slime Why did you add borax to the PVA polyvinyl alcohol solution?
Slime is sometimes described as a reversible cross-linking gel. The cross-linking between the polymer chains of polyvinyl alcohol occurs by adding borax, Na2B4O7. 10H2O (sodium tetraborate). The borate ion can make weak bonds with the OH groups in the polymer chains so it can link the chains together as shown below.

STEP 2: Stir in 1/4 tsp of baking soda (You can use 1/2 tsp for thicker slime). STEP 3: Add food coloring, glitter, or confetti to this mixture and mix to incorporate everything.
Is polyvinyl alcohol sticky?
Low-temperature gelation of poly (vinyl alcohol) (PVA) solution was performed in the presence of CaClz. The resulting PVA hydrogels showed high stickiness and excellent water-holding ability. These properties became more remarkable with increasing CaClz concentration in solvent.
Is PVA water soluble?
WaterPolyvinyl alcohol / Soluble in
PVA is highly soluble in water as it comprises a large amount of hydroxyl groups, which interact with the water molecules through hydrogen bonds.
How long does it take for polyvinyl alcohol to dissolve?
If you are starting with a highly hydrolysed pva say 98-99%, you may wet it first by stirring in cold water for about 30 minutes then raise the temperature to 95 degrees Celsius, it should dissolve in about 30 minutes.
Is Elmer’s glue same as PVA?
Polyvinyl acetate is a component of a widely used glue type, commonly referred to as wood glue, white glue, carpenter’s glue, school glue, Elmer’s glue (in the US), or PVA glue.”
How do you make slime with PVA glue but no activator?
Mix together 1 cup (236.58 mL) of school glue and 1 tbsp (14 g) of baking soda. Pour 1 cup (236.58 mL) of school glue into any kind of bowl. Add 1 tbsp (14 g) of baking soda and mix it in thoroughly using a metal spoon. This recipe creates slime that has a consistency similar to slime made using Borax.
How do you make liquid slime?
Mix 1⁄2 cup (120 mL) of clear glue and 1⁄4 cup (59 mL) of water in a bowl. Measure out 1⁄2 cup (120 mL) of clear school glue and pour it into a bowl. Add 1⁄4 cup (59 mL) of water, then stir it in with a spoon. Keep stirring until the water is completely mixed in and the texture is consistent.
