PLASTICIZERS?
Whenever I read about plasticizers for polymer rubbers, I get the impression that these substances can be obtained only from chemical companies. Does
anyone have knowledge of common readily available substances that when added to polymer rubbers will make them malleable
& plastic?

If leaching and and eventual raising of the Glass transition temperature is not a problem, try long (C18 at least) chain esters. They will work, but
have the additional problem of not being U.V. stable.

Dipropylene glycol benzoate is a UV stable plasticiser. I do not know if this could be made from Proylene glycol and a benzoate source?

I have some information that substances such as non-detergent mineral motor oil, petroleum jelly, and even ladies' facial cold cream, when added to
certain polymer rubbers will cause them to become soft and plastic; is this true? If not, what other commonly available substances can be used to
make polymer rubbers malleable?

Maybe try the casien based white wood glue.
It remains flexible and cures by water contact
Reminds me of the "animal glue" referred to in older texts for electroplating.
WTF is "animal glue", anyway?? Tried some white carpenters glue but it's casein and I'm wondering if the so called animal glue is even made anymore.
Good old "elmers" nowhere to be found here but can get concentrated HNO3, clear and tranparent, from the hardware store.
