    Bearing
In summary, the conversation revolves around the use of Styrofoam, a brand name for a type of polystyrene, for bearing heavy material weight and its weight as a material. It is noted that the load-bearing capacity depends more on the engineering specifics of the structure than the material itself, and that Styrofoam can be used to create light-weight structures without compromising strength. The original poster is advised to wait for responses from experts in the field.

Dear All,
I have few questions:-
Is styrofoam useful to bare heavy material weight?
Is it light weight material?
Waiting for reply.
Thanks in advance.

Hi. I'm surprised that nobody has answered this yet. I was going to yesterday when I first read it, but waited because I figured that one of the experts would respond.
Styrofoam (with upper-case 'S') is a brand name for a particular type of polystyrene. In general, it has a low density (weight is a function of gravity), but there are different forms of it. The same stuff that makes semi-rigid insulation panels also makes disposable coffee cups and 'peanuts' for packing fragile equipment... and none of those have the same consistency.
The load-bearing capacity comes more from the engineering specifics of the structure than from the material itself. You could easily make a pyramid out of used cups that would support a person, or use beams made of the denser insulation material to build a truss system to support the same load with less volume of plastic.
A lot of things from aeroplanes to movie models are made from a polystyrene core covered with something like Fiberglas (also a brand name) or carbon fibre. It gives a very light-weight structure without compromising strength.
That's the best that I can do for you; it's not an area that I have much knowledge about.

You're totally welcome, but bear in mind that it's only a 'quick and dirty' answer. There are structural engineers and chemists here who can help you far more. You'll get better responses before too long.
 

Related to Can Styrofoam Support Heavy Loads?

1. What is the maximum weight that Styrofoam can hold?

Styrofoam's bearing capability depends on the density and thickness of the material. On average, a 1 inch thick piece of Styrofoam can hold up to 60 pounds. However, this can vary depending on the specific type of Styrofoam and its quality.

2. Can Styrofoam support heavy objects?

Styrofoam is not typically used for heavy duty support as it is a relatively lightweight material. It is best suited for holding lightweight items such as packaging materials or insulation. Using Styrofoam to support heavy objects can cause it to break or compress, reducing its bearing capability.

3. How does the temperature affect Styrofoam's bearing capability?

Styrofoam's bearing capability is greatly affected by temperature. As the temperature increases, Styrofoam becomes softer and weaker, reducing its ability to support weight. In extreme temperatures, Styrofoam can even melt or deform, further decreasing its bearing capability.

4. Is Styrofoam suitable for outdoor use?

Styrofoam is not recommended for outdoor use as it is not resistant to UV rays and can easily degrade when exposed to sunlight. It is also not waterproof and can absorb moisture, which can further weaken its bearing capability. If used outdoors, it should be coated with a protective layer to prevent these issues.

5. Can Styrofoam be reinforced to increase its bearing capability?

Yes, Styrofoam can be reinforced with other materials such as wood or metal to increase its bearing capability. This is commonly done in construction projects where Styrofoam is used as insulation. However, it is important to note that the overall bearing capability will still be limited by the strength of the Styrofoam itself.
