What is the difference between rigid polystyrene plastic and expanded polystyrene?

∙ 12y ago
Rigid polystyrene plastic is a closed cell of light weight, rigid & foam plastic that is derived from petroleum and natural gas by products. It is hard plastic in one word. This is used to make plastic containers and insulators.
On the other hand, expanded polystyrene is derived by expanding the regular foam molecules by 50 times their volume using a blowing agent (pentane gas). This is used to make packaging materials.

What is the difference between bulk density and density?
It is the difference between the density of a bulk sample, and the density of a homogenous piece of the material being measured.The difference between the density of a pile of gravel, and one stone from the pile, for example. the pile is less dense.Or styrofoam peanuts versus polystyrene plastic, the same material in a different form.Used more in engineering, for things like earthfill, coal hauling, etc.

What is the difference between polystyrene and Styrofoam?
Polystyrene is a plastic that can be made into many products, which can be dense, or can be in the form of a low density foam, called Styrofoam.

What is the unit cost of polystrene?
Polystyrene is often sold in bulk on a m3 (cubic meter) price in Europe The cost is also effected by the density of the polystyrene. That is assuming your talking of expanded polystyrene foam, polystyrene is also available in hard plastic sheet form. dunno
