Practical uses of laboratory tests: elongation and tensile strength tests.

14 June 2021

One of the most used laboratory tests to evaluate the quality of a compound / O-ring is the elongation and tensile strength test. The test requires a standard specimen / O-ring to be “stretched” until it breaks. At that moment, the percentage of elongation that it has undergone and the…

Dynamic applications are defined as those where the seals act as dividers on the surfaces of two elements that move one against the other. We position dividing the dynamic applications of an O-Ring into alternating and rotating linear applications.

Material selection – FKM

23 February 2021

FKM, also known generically as FPM, are a family of elastomers that can be defined as “fluorinated compounds“. Thanks to the presence of fluorine in the formulation, they are considered high-quality compounds, with generally excellent resistance to high temperatures and the attack of chemical substances. Characteristics and fields of use…
