To talk about silicone-filled gaskets, we will introduce you to the complexity of sealing fluids.
In the food, pharmaceutical and fine chemical industries, among others, the management of their fluids, in itself, is not easy.
And it gets more complicated when the fluids have a certain viscosity or involve particles in suspension. We are referring to slurries, syrups, slurries, leachates, molasses and food fluids, among others.
On this occasion, we are going to see how these fluids condition the design of dynamic seals to be installed in rotating equipment...
In some cases we find that the dynamic sealing of a hydraulic cylinder or other similar dynamic application is designed to mount O-rings or, at most, “X-ring” type seals.
Sometimes these applications operate at pressures or speeds that are beyond the reasonable limit of such seals.
The result is that these O-rings, working as rod or piston seals, suffer premature wear that compromises their life and/or effectiveness.
What can be the solution? Due to the higher working speed or that the pressure is higher or...
Frequently, one of the problems that often appears in the spare parts warehouse of a factory is the variety of flat gaskets, not in sizes (although this is also true) but in materials.
And there are cases where, for the same flat gasket, up to 3 different references coexist in the warehouse. This implies an increase in costs and inefficiency in the manufacturing processes.
In a plant, roughly speaking, 30% sealing gaskets work in severe conditions where restructured PTFE (rPTFE), expanded PTFE (ePTFE), graphites and micas, among other materials, solve...
