Poly urea greases

We use Exxon Mobil PolyRex EM on our electric motors and high speed bearing applications with good results. So far I've only dealt with Mobil products. I'm sure there are many manufacturers with Polyurea greases.

Good luck.

I dont mean to but in but what applications were you thinking of or wanting to use it in and conditions etc. thank you

Hello,

thx for your answers. I guess I have to explain that at first I would like to get an overview of Poly urea greases. I like to get know the application areas of poly urea greases and the brands (products) which are used in that areas. Hence the answer from "remmious" is exactly that what I need.

Best regards

Just remember there can be some compatibility issues with polyurea and lithium and lithium complex greases. Companies seem to still be riding on the fence with this question and haven't put a definitive answer yet. So we use it strictly on motors and a couple of high speed fan rotor bearing applications. These fan bearing applications are very few and its an area where generally only 1 mechanic works on them. Other bearing applications we use Li-complex greases just to keep cross contamination down.

Just some more personal perspective on the subject.

Any further ideas where PU-Greases can be used?

The polyurea greases is not compatible with any bases, i recomend you the polyurea grease to MOLYKOTE is the G0100EM grease.
You can to use for any aplications to high speed bearing,and the contamination of wather is present.
its very important to wash the bearing before to engrase.

Hi Eva,
Polyurea thickeners are very good and can replace most grease applications.
The Best manufacturers are USA and Japan,
USA we have experience with and one of the best was Witco, now Exon Mobil, Remmious's recommendation, we agree,
Schafer (Spelling??) was taken over by Shell so their polyurea greases will also be OK,

Polyurea's are non soap greases and are usually incompatible unless the application can be flushed greases until > 80% of the old grease has been replaced with new and most applications will behave but with any change over like this care and attention is important.
We like the polyurea thickener as it has thixiotrophic characteristics where the grease can shed base oil under pressure and provide additional lubricity and then reabsorb the base oil once the pressure reduces,
soap greases do no have this ability and once sheared and separated will not recombine.

Dear All,

first of all thx for your answeres.

Pls can you tell me something about shere stability of PU-Greases. I've found on internet different opinions. On some pages I found the information that some PU-Greases are shere stable and some not. Do you know the reason for it?

best wishes
Eva

Eva,

Type of product will of course depend on application.

Stamina RLS2 and Stamina RL2 are excellent products for electrical motors, fans and pumps. These products have extremeley high TREFs and excellent shear stability.

Stamina HDS is an excellent product for slow speed bearings such as f.ex. main shaft bearings on wind turbines.

Stamina EP2 is an excellent product for medium speed bearings running at elevated operating temperatures.

Stamina 0511 is a product especially developed for continuous casting machines and roll transfer tables such as f.ex. furnace discharge tables and cooling beds.

Cheers,
GG

Mody - Polyurea greases have some nasty raw materials and the folks manufacturing them have to wear pretty extensive PPE compared to most grease manufacturing processes. However, when these materials react, the resulting thickener is pretty benign.

You can get best Polyurea greases both in mineral and synthetic oil
www.elba-lubes.com

This is amazing. The polyurea greases mineral oil is really helpful and your site elbs-lubes.com is really helpful.

Sorry Herbert, I don't see it. I checked the Elba site and didn't find it "amazing", as you put it. What am I missing?

Hi JMOrgan. I think you are getting some issues with. it's fine. You can just check this link I am pasting. http://www.elba-lubes.com/file...A%20POLYUREA%202.pdf

The numbers are comparable to mine. A few a point better, a few a point worse. What is the cost for tubes?

Thx in advance for your answers

you can use Elba Polyurea 2 or Elba Polysyn 2 they are both polyurea based greases with mineral as well synthetic. I have very experience with Elba Lubrication

Petron Plus addresses water issues as well, also high temperatures, plus with the added anti friction reducers with negative ionization
your operating costs and down time would be less, not to mention increased equipment life.
