The hardness of the
materials that are non-metallic like rubber, foam and plastic can be measured
suing the durometer. This is the
international standard for the measure of the hardness of such materials. The hardness of a material can be defined as the resistance to
surface indentation, and the durometer tests this quality of the materials. Any
material can vary when it comes to the hardness and any type of hardness is
used for one or the other industry. For instance, rubber that is very hard is
required to make skate board wheels, while runner that is soft is needed for
the mats.
While the harder materials
have more amount of resistance, they can also withstand wear and tear. They are
not much flexible, which might be the quality required for the manufacturing of
various products. Various scales are a reason used in the durometer. In various scales the reading are different for the same
material. Checking the reading with regards to the purpose of the material is
vital. For instance, in A scale the 70 and in OO scale 95 is require for the
shoe heel. The same should read as 22 in the D scale.
