DIY Recycled STYROFOAM Polystyrene EPS to a Clear Sealant Glue

Introduction: DIY Recycled STYROFOAM Polystyrene EPS to a Clear Sealant Glue

About: You may recognize Dan and Denise Rojas from their appearances in various made for tv movies and national commercials. As the hosts of Green Power Science, they share Fresnel lens and alternative energy ideas, …

Pure citrus peel oil aka D-Limonene transforms polystyrene (styrofoam®) into a very clear usable sealant that has a great uv resistances and dries very hard and very clear.
This also works with many other types of styrene based plastics.

Pure Acetone will reduce styrofoam much faster BUT it makes a milky white goop. Not the clear gel we are making.

    I mixed styrofoam with acetone, and the styrofoam shrunk down into a blob at the bottom of the acetone. It did NOT form a milky white goop. That is actually what I was trying to make, the milky goop styrene.

    Nice !!
    I've been trying to recycle polystyrene for a while using acetone, but never had great success.
    The reason being that once you shape the "goo" , it dries on the outer part first, of course, leaving the inside soft, because the hard part cured and did not allow the remaining acetone to evaporate out.

    Is there a way to make your own limonene?
    Are you sure that there are not other stuff in the spray (like the gasses) that interfere with the process?

    This is a no gas product. The inner can is a plastic bag filled with the liquid surrounded by the gas so the orange peel oil is pure, the gas compresses the bag.
    The drying time can be difficult with large masses.

    Citrus fruit peeling can be pressed or "

    It is also sold by the gallon on the net (NOT EBAY)
