We use two types of silica as a thickener in our grease range, both fumed silica and hydrophobic silica. Silica is not to be confused with silicon or silicone. Fumed silica is hydrophilic (water-loving) and has a thixotropic behaviour due to it’s time dependent recovery of apparent viscosity after shear…
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…
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…
