The synthetic oil and grease we offer for vacuum and cleanroom related applications are chemically stable, non-toxic, low vapour pressure lubricants. These lubricants can improve the performance and extend the operating life of high-speed bearings, linear guides for motion control, vacuum pumps, and many other components; designed for high-vacuum and cleanroom environments such as semiconductor wafer fabrication equipment, as well as flat panel, solar panel and LCD manufacturing equipment.
Please take a look at the various in-vacuum or cleanroom related lubricant articles below, including test videos, theory and product selection help.
Sometimes it can be smaller than a grain of sand. Manufacturing equipment in Vacuum and cleanroom environments are so sensitive that even microscopic particulates can cause product failure. In a bearing, for example, any particle that acts like a ‘speed bump’ in the motion of the bearing, no matter how…
We have a number of base oils to select from when formulating a grease. Quite often the first way to start the product selection process is ruling out grease that doesn’t have the temperature capability that is required in your application. The chart featured on this page gives the reader…
There are a variety lubricant additives that we have the ability to include in our grease formulations. Note that we describe our additives, we use terminology relating to the benefit of the additive rather than than giving details of the chemical way in which the benefit is achieved; we don’t…
The Knudsen effusion test method is used to determine the vapour pressure at several temperatures. Below is an example of how the Knudsen vapour pressure test results are displayed on a technical data sheet of one of our lubricants: As you will see, our chosen unit of measure is Torr.
The purpose of the Pour Point test is to help define the lowest operating temperature for an oil. During this relatively simple test, the temperature is slowly reduced and it is noted at what point the fluid becomes too viscous to flow. Some times Pour Point is referred to as…
The grease range we offer uses a wide variety of thickener systems. The various characteristics of the thickener (also known as gellant – US terminology) gives the ability of our grease formulators to meet the challenges faced by our customers. Formulating a grease generally involves balancing the pros and cons…
Polytetrafluoroethylene (PTFE) is a fluorocarbon-based polymer which has the appearance of a white powder but the particle size varies from micron to sub-micron; final particle size depends on the milling process. The polymerisation process controls the molecular weight of PTFE and the density is approximately 2.2 g/ml. PTFE has a…
Perfluoropolyether (PFPE) oils are chemically inert, capable of handling extreme temperatures and also hazardous operating environments, PFPEs are resistant against fuels, solvents and chemicals, examples such as sulphuric acid and sodium hydroxide. PFPEs are composed entirely of carbon, fluorine and oxygen. PFPE summary: Keep in mind that if a PFPE…
What constitutes a grease? There are three main components that make a grease, base oil, thickener (sometimes called gellent) and an additive package. Making a grease is thought to be like extreme cooking and in the video, we tried to give an insight into the almost bewildering options and permutations…
Why should you choose a grease rather than an oil, if you have the choice? There are some simple or practical reasons and some more chemical advantages. First and foremost, a grease will ‘stay in place’. How good a grease is at staying where it has been applied is down…
