Lubrication regime explanation-Types of lubrication

There are three primary lubrication regimes, which are boundary, mixed, and hydrodynamic lubrication. Lubrication regimes describe the type of lubrication film that is created under specific operating conditions and is dependent on the degree of contact between surfaces. Boundary Lubrication During boundary lubrication, opposing surfaces meet with little or no…

Base oil temperature capability information

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…

Lubricant Additive overview

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…

Introduction to Polyglycol

Polyglycol or Polyalkylene Glycols (PAG) are a family of products formed from the polymerisation of one of more alkylene oxides. PAGs are made from ethylene oxides, propylene oxides, which in the presence of an alcohol initiator and a catalyst form a long chain polymer. Other names you may come across…

Grease thickener characteristics

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…

Understanding the Viscosity Index data point

Viscosity Index (VI) is a data point reference used on our technical data sheets. The VI data point or scale was originally devised by the Society of Automotive Engineers (SAE) in the USA. VI is a unit-less number that gives an indication of how a lubricating oil (or base oil…

Introduction to Alkylated Naphthalene

Alkylated Naphthalenes (AN) are a reaction of olefins with a naphthalene nucleus resulting in a base oil with excellent thermal and oxidative stability. In addition AN has first-rate hydrolytic stability and is miscible with other synthetic hydrocarbons, most notably Polyalphaolefins (PAO). Alkylated Naphthalenes summary: Keep in mind that if a Alkylated…

Understanding Kinematic Viscosity

Kinematic Viscosity (KV) is a type of viscosity data point that you will see on all our synthetic lubricant technical data sheets. There are different ways to measure the viscosity of a lubricant as the subject matter is not simple. Kinematic Viscosity is an oil/fluid resistance to flow under the…

Introduction to Polyphenylether (PPE)

Polyphenylethers (PPE) are long chain aromatic ethers that consist of benzene rings (phenyl groups) joined by oxygen atoms. PPEs are ideal for radiation resistant applications, used for example in nuclear power plants and MRI scanners. Polyphenylether summary: Keep in mind that if a Polyphenylether is used as the base oil…

Semi-Automated Dispensing of Lubricants

For grease dose accuracy, consistent repeatability and process control, a semi-automated application method should be considered. The system setup we are proposing in this article involves the purchase of a small benchtop/desktop pneumatic dispensing device and the chosen grease being purchased pre-filled in specialist syringes that work with these desktop pneumatic…
