When is an O-Ring used? Dynamic applications

7 December 2020

Although the O-Ring is not very suitable for dynamic applications (it is rather suitable for static applications), there are areas where it is used for seals on moving devices. Dynamic applications are defined as those where the seals act as dividers on the surfaces of two elements that move…

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.

When is an O-Ring used? Applications in drum presses

7 December 2020

One of the applications in which the O-Ring is fundamental is that of drum presses. Drum presses are pumping and melting devices that allow the dosing of thermoplastic materials directly into the production line. They are usually made up of a piston (plate) press, a structure that guarantees rigidity to…

Operating temperatures of O-Rings

7 December 2020

High and low temperatures greatly influence the behavior of elastomers High-Temperature effects on O-Rings At high temperatures, the compounds are subject to deterioration causing different effects: the hardness decreases, but the effect is reversed if the temperature drops again. the percentage elongation increases and, consequently, the load required to break…

O-Ring applications: the aspects to be assessed when choosing the material.[Part 1]

7 December 2020

The choice of an elastomeric material depends on many factors: temperature of use, environment, fluids/gases with which it comes into contact and for how long, mechanical, electrical characteristics, etc. O-Ring: The most important factors to consider when searching for the correct compound for each specific application.
