Two ageing potentiometers had developed electrical contact noise which was impacting on the usability of the equipment in which they serve. Both potentiometers required cleaning and restoring to full operation so they could be returned to service. Components will perform satisfactorily and continue to operate for many more years of…
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 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…
Yamaha DSP series amplifiers can be purchased second hand online at low cost. Older models have a common problem with the volume control because the volume control knob movement often does not correlate correctly with the dB level readout on the VFD screen reading. The fault is due to the…
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…
If you are trialling the use of a grease or oil in a prototype device then you will appreciate how crucial lubricants can be; extending the functional life of components, improving the tactile feel of customer operated controls…the reasons to include a lubricant are many and well worthwhile. Before you…
Polyalphaolefin (PAO) oils are stable, lubricious fluids that are compatible with most plastics and elastomers. PAO oils are considered a great replacement for petroleum based products, are used in countless applications and industry sectors. PAO summary: Temperature range of -60 to 125°C Relatively low cost Excellent wear reduction Good plastic/elastomer…
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…
