Yes you can use an exterior paint inside but it may not be as scrubbable as a good interior paint. This is because most exterior paints are designed to hold up to withstand suâ¦nlight and multiple freeze-thaw cycles but are not meant to be hand scrubbed, so you may see some burnishing if they are scrubbed.
An isotropic material is one which looks the same in every direction. We cannot define any special direction using the material properties. In other words, none of the properties depend the orientation; it is perfectly rotationally symmetric. Note that in order to be isotropic the material must be homogenous on the length scale of interest, ie the same at every point in the material. For instance, rubber is a very isotropic material. Take a rubber ball, and it will feel the same and bounce the same however you rotate it. On the other hand, wood is an anisotropic material: hit it with an axe and it will take more force to break of you are cutting across the grain than along it.
Each kind of plastic has a different raw material; generally it's  fairly obvious from the name of the plastic (for example: the raw  material for poly (vinyl chloride) is v â¦ inyl chloride, IUPAC name  chloroethene).   A lot of them are ultimately based on petroleum (crude oil)  derivatives.ach kind of plastic has a different raw material; generally it's  fairly obvious from the name of the plastic (for example: the raw  material for poly (vinyl chloride) is v â¦ inyl chloride, IUPAC name  chloroethene).
