I got 1043 kg/m3 for pure SBR from: http://www.tpl.fpv.ukf.sk/engl_vers/thermophys/2004/Boh-Vre.pdf
If I am not mistaken, the density of SBR would vary. It is made up of styrene and butadiene, and depending on the percentage of SBR that they make up the density of SBR would be different. You might want to take this into consideration.
rubber would be an example of something that does not allow electricity to move through it easily
Mercury Iron Carbon tetrachloride Rubber stopper Water Cork Oil Air You might want to think of something better than a rubber stopper; they tend to gum up and dissolve into the carbon tet layer after a while.
Rubber ducks float because:They are made from a lightweight substance meaning upthrust from the water can counter-balance the downward force from the duck's weight.Their bottom has a large flat surface area, meaning the upthrust has a larger area to push against.They are filled with air, which is lighter and less dense than water, so it will naturally push upwards in water (think of when you blow bubbles underwater-the bubbles float upwards)Hope I helped :)
Yes, we can erase pencil marks with rubber because erasers are made out of rubber
Rubber boots, or rubber soles on boots, is an insulator
No, the density of a rubber stopper is less than the density of water. Rubber has a lower density compared to water, so a rubber stopper would float on water.
The density of rubber can vary depending on the type of rubber. Generally, the density of natural rubber is around 0.92 g/cm3 to 0.96 g/cm3, while synthetic rubbers like neoprene have densities ranging from 1.1 g/cm3 to 1.6 g/cm3.
The density of a thick rubber band can vary depending on the specific material and composition of the rubber. However, most rubber bands have a density around 1.0 to 1.2 grams per cubic centimeter.
The density of rubber can vary depending on the type of rubber used, but it typically falls within the range of 0.92 to 1.5 grams per cubic centimeter. It is important to note that different types of rubber, such as natural rubber and synthetic rubber, will have different densities.

When rubber is heated, it typically expands and its density decreases. This is because the increased thermal energy causes the rubber molecules to vibrate more, creating more space between them and leading to a decrease in density.
The density of a rubber stopper is typically less than the density of water, which is 1 g/cm³. Rubber stoppers usually have a density ranging from 0.9-1.1 g/cm³, making them less dense than water and able to float on its surface.
A penny has more density.
density
It depends on the density of rubber. Different kind of rubber have different density so different weights. weight = volume X Density in your case the volume is 1cuM. Natural rubber - 920 Kg/cu M Neoprene Rubber - 1230 kg/ cu M Silicone Rubber - 1150 kg/cu M EPDM Rubber - 860 kg/cu M Ramki- India
Rubber has a lower density compared to oil, which causes it to float on the surface of the oil. This difference in density results in a buoyant force that pushes the rubber to float rather than sink.
