If I interpret your question correctly, it's meaningless.

Polymer capacitors (ie, plastic-dielectric caps, such as polystryrene,
Mylar, and Teflon) simply cannot produce the huge capacitances in small
spaces that electrolytics can. They cannot easily replace electrolytics.

How much bigger (in volume) are polymer capacitors than
electrolytics for the same value?

Are there any types of capacitors with substantially better life
than electrolytics that are small enough to replace electrolytics?
If so, how do they compare in price?
