Is plumber’s grade silicone toxic after curing?

Abdallah A asked:


I wanted to use silicone to create molds that hold food. I know that I should be using food grade silicone, but it doesn’t exist where I live.

Plumber’s grade, on the other hand, is readily available. After it cures, is it toxic? I’d be thankful for actual replies :)

    they are different composition, plumbers grade silicon may have impurities you do not want to ingest and will also have a different composition to that used in moulds and may well melt at hight temperature

    It contains antifungal compounds, which are toxic.
