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:

Temperature range of 10 to 250°C
Radiation, chemical and acid resistant
Outstanding high temperature capability
High surface tension but excellent lubricity
Can have compatibility problems with some plastics/elastomers
High cost
Viscosity Index 60 to 360

Keep in mind that if a Polyphenylether is used as the base oil for a grease, the thickener and additives also used in the formula will have an influence on the final characteristics and performance of the finished grease/lubricant.

Take a look at our typical thickener systems characteristics used to make a base oil into a grease.

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…

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…

50gram tube overview

Much of our grease range is available in a 50gram tube. The 50gram tube is ideal for small applications, infrequent use or field service kits as the 50gram tube has a screw cap lid and already has a 1.52mm (0.06inch) hole/orifice at the end of the nozzle. The nozzle can…

Introduction to Polybutene

Polybutenes (also called Polybutylenes or Polyisobutylenes) are hydrocarbon synthetic fluids produced by the co-polymerisation of butenes and isobutenes. Polybutenes differ from most other oils by decomposing at temperatures of 250°C to 275°C through a depolymerisation or unzipping mechanism. Polybutene summary: Typically we blend polybutenes with Polyalphaolefin (PAO). Keep in mind…

Introduction to Polyalphaolefin (PAO)

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…
