Plastic has never been in Powder Toy.
You can use different elements to compromise for different properties of Plastic.
Hay, let's add Sulfuric Acid, because it is a stronger acid than ACID and it should eat through much faster, and if you mix it with another new element Nitric Acid you should get another new element called Glycerine which can be mixed with a new gas called Nitrogen or N2 for short to make NITR!

Everyone should either have constructive critisim or state their reasons why one support their side. Simply raging at others with caps or using examples how we should make a search element isn't helping.
Didn't we have plastic somewhere in the older version, but it sort of broke OIL so it was removed..?
"need" implies that it is absolutely vital. Plastic is not vital. Your suggestions are no useful for TPT as you have stated any features whatsoever.
I've not played a version with plastic, but I heard the stories. Cracker/Simon coded it, but when so, oil spazzed up big time, so they removed it.
