How does styrofoam soften?
Softening method 0 1 method 1: add the foam made of toothpaste into styrofoam and knead it to soften it.
Pay special attention when using toothpaste to save styrofoam. Don't add soda toothpaste, and don't put toothpaste directly in it. Instead, soak the toothpaste first, and then add it into styrofoam step by step to stir. The effect will be better. Besides toothpaste, we can also use other foams, such as shampoo and facial cleanser.
Method 2: Add hot water to styrofoam and stir.
Add water to foam rubber to soften it. It should be noted that the added water must be hot water, so that the foamed rubber can be softened and not easily broken.
Method 3: Add glue and glycerin to the styrofoam and mix and stir to soften it.
Adding glue and glycerin is actually making new styrofoam on the original basis, and the effect will actually be better, but it is not as simple as the first two methods, and the materials will be harder to find.
Method 4: Adding hand cream or face cream to styrofoam can also soften styrofoam.
First, put the styrofoam that is a little hard into the basin, squeeze in a proper amount of hand cream or cream, and rub the styrofoam by hand; After rubbing for a while, you can see that styrofoam can be extended into a film; Continue to knead, when the styrofoam becomes wiredrawn, it shows that it has been completely softened and the effect is very obvious.
Method 5: Heat with fire for a few minutes.
Hardened styrofoam will soften after being heated with fire for a few minutes; The disadvantage of this method is that the styrofoam that becomes soft after heating will become hard. If the styrofoam is no longer soft after repeated heating, it can only be thrown away.
Method 6: soak in hot water for a while.
Foaming rubber with hot water will soften the foamed rubber, but the disadvantage of this method is the same as that of heating directly with fire: it can only be softened temporarily, but not for a long time.
