Significance of Rubber

Let we understand that what is the Rubber Exactly!!!

We can say that Rubber is Visco-Elastic Material Now here we can say that Viscosity is resistance between two layers and elasticity is tendency to retain its own shape and rubber is same thing that we can starch it and it will retain its own shape after some.


Here we have various methods to test rubber properties in many manufacturing Industries.......

1. Rehometer
2. Moony viscosity meter
3. IRHD Harness tester
4. Shore Hardness tester

Now, before know about these various test methods we should have knowledge regarding to some variation observed in final result.

How we can prevent?What are the methods to control these variations?

Main reason for test result variation is manufacturing condition of Synthetic Rubber & for Natural Rubber where it grows?
