Rigid foams can be made by mixing a polyol (resin) with an isocyanate (hardener) and a blowing agent (to create bubbles). This mixture is typically stirred and poured into a mold where it expands and cures to form a rigid foam. The specific formulation and process will vary depending on the type of foam desired and the intended application.

A polyurethane is any polymer consisting of a chain of organic units joined by urethane links. It is widely used in flexible and rigid foams, durable elastomers and high performance adhesives and sealants, fibers, seals, gaskets, condoms, carpet underlay, and hard plastic parts. Polyurethane products are often called "urethanes". They should not be confused with the specific substance urethane, also known as ethyl carbamate. Polyurethanes are not produced from ethyl carbamate, nor do they contain it. And if you want to know more about the polyurethane and polymer industry, see the Related Links below.
it's a lithosphere
A lightweight and rigid.

i think its when you are make a float and you put a soda in it in it foams a float
Plastics are developed for various purposes, and often blended together to achieve what the company is looking for in performance. In the case of polyurethane, there are versions that are soft foam for mattresses, rigid foams, other in between, and also rigid.

A rigid shape is when you cant push/pull on it and make it turn into a different shape. You can make shapes rigid by adding "braces", which are lines that you put inside the shape to make triangles (which are rigid). For instance, a square is notrigid. To make it rigid, you would put a brace inside diagonally. This would create TWO triangles, and therefore, rigid. ~xDragonx
Cut panels of rigid insulation slightly smaller than openings. Fill in gaps around rigid panels with liquid nails or any brand of construction adhesive caulking that is compatible with stryrofoam (polystyrene) or polyurethane foam, depending on what type of rigid foam you purchased. I prefer polyurethane foam and seal the perimeter edges with Great Stuff spray foam or DAP latex spray foams. That way you don't have any heat leaks around the edges of the rigid foam even if the rigid panel is between warped rafters or studs.
Having foams or fine bubbles. Covered with or containing foams.

A diamond is not a rigid shape unless it has a brace. A brace is a diagonal line you put inside shapes to make them rigid. Triangles are rigid so if you put a brace in a square to make two triangles the square is now rigid.
yes it can
The lithosphere makes up the rigid surface of the Earth.
