It's not entirely clear what you're asking. "Plastic" means, essentially, that something can be molded into another form.
"Malleable" strictly speaking means that something can be hammered into another form.
Plastic is also used to refer to polymeric materials. Most plastics in this sense are not at all malleable; thermoplastic materials can be heated and reshaped, but generally this is not done by hammering.
Malleability is a characteristic associated with metals.
One example of a solid that is malleable and does not dissolve in water is gold. Gold is a metal that can be easily shaped without breaking, making it malleable, and it does not react with water, so it does not dissolve in it.
Raw sulfur is a powder. If mixed with water to make a paste then yes.
Malleable
Many - but not all - are poor conductors of electric current.
Gold is a malleable element. Silver is another malleable element.
no, only the cartilage of the nose is malleable because it is made up of mostly water

yes because malleable can also mean 'easily influenced' so when you add water to water the flour binds readily, hence 'easily influenced'

malleable
Because lead is malleable
Gold is extremely malleable.
no it is not malleable

They are malleable when heated and they are not water soluble.
Hafnium is malleable.
