Four Main Categories of Polymers

Polymers are held together by_______ and______

It alludes to how effectively it tends to be damaged or indented during static stacking.

Most polymers are designed to be impact resistant and impact tests can not only indicate durability, they can also indicate the service life of a finished product.

                        In polymer,_____ happens in unnoticeable areas therefore it’s hard to discover, which leads to notice the material having a normal look but in fact, it does some embritted parts and lost its mechanical strength.

Does polymers corrodes?

The main advantages of this methods are the possibility of on-site evaluation,repeatability at the same place during strucutural service and quick test results

It is a non destructive testing method which uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects
