Silicone: DIY Memory Foam. PLA safe. Non-solvent method to thin pour silicone. Mold Making
Ғылым және технология
Second in a requested series on thinning silicone without Naptha or other hydrocarbon solvents.
This method produces a very silky and light weight foam. This method can be tricky, so watch the entire video.

Fun fact: The key to make a SUPER-SOFT & SPONGEY Memory foam is: The Foam Itself. If you have a spare electric stirrer or are very patient and strong, you're going to have to stir the ingredients with a surfactant (casein, eggs, etc.) tediously until the whole mixture reaches a foam texture (like soap bubbles). Once it reaches a super foamy texture, you shape it however you want on a pan and bake it at a low - med temperature for 1-2 hours or until it reaches that sponge-ness you like. The key to a foam is that the foam has to cure AS A FOAM! P.S.: Adding Fiber into the foam like cotton, linen, etc could help in giving the foam it's shape.

use activated yeast to a small batch of silicon & see the magic. should be mixed fast and pour to mold

I am so glad you like my videos. Do you mean something like Resin? Resin pours like liquid and then sets hard.
I’ve been 3d printing molds for foam silicone. My favorite so far is a stellated dodecahedron that I’ve been making foamed silicone with and the cat just loves them, but i use spray silicone to thin plus baking soda and vinegar to expand. The baking soda speeds cure time as well it seems. I will try this method next. I wonder what causes this recipe to foam and is the air bubble size adjustable?

Air bubble size I am sure is adjustable. The baking soda also holds moisture so will also cure silicone. The foam is a basic science experiment, as a kid we all made volcanoes in science class, and how type A fire extinguishers work. I love your idea, as I have a cat. Thanks for sharing.
thanks for sharing i still didn't get how you thinned silicone ! what did you use to thin it ? thanks in advance. your Fan from Jordan.

I have a mold for a ceiling medallion. I am trying to figure out what light weight material to pour in that will give details and allow for painting. Any ideas?

Certainly not silicone. Have you considered Plaster of Paris? I can't imagine anything being much lighter than PP.
Which one you will recommend to use to make molds to pour cold process soap in?

Wau - tried it right away - but the silicone didn't absorb the glycerine it didn't foam up and if anything it coagulated fast into a lump. Used small tube of clear silicone from plastic padding and 85% vegetable glycerol from the pharmacy - any hints? Would like to use it for stopmotion puppets

Yes, use the white 100% silicone. The type that emits Acetic Acid during cure. And it takes a lot of mixing. Don't use the clear. The Glycerine will weep out during cure. It takes a long time. That sounds cool. You have a wire frame? I can see this working for that.
Is this the same material used in mattresses ?

Sir, I'm searching for non toxic foam to replace PU foam for making nose filters, is it possible to make open pore supersoft sponge /faom with silicon mix? Please try and send me the process.

It is possible, and the video will show you how. Good luck! Discovery is a challenge, but stick with it! PU is also non-toxic, you should not rule it out.

You may want to look into Latex or Rubber. They are stretchy and natural. I don't know how to make silicone more stretchy. If I ever run across a method, I will share it.

You mix the tube silicone with pure silicone oil. The more oil, the softer and stretchier it will be. It will work up to a 1:1 ratio, but try to stay under that (ie. less oil than tube silicone) or else it will never set and you'll just have a sticky blob. I use it for mold making all the time.

It did not notice that. I made several batches, perhaps I showed a different one than that I demonstrated. However, it can shrink, depending on how much Glycerine you use. Good eye.
