Nyloil Substitute

[burobot]

I am looking for a Nyloil substitute material.

http://www.matweb.com/search/SpecificMaterial.asp?bassnum=PCAST0

It is for a wheel that needs to withstand impact from heights of 10 ft +, be shock absorbing, and withstand a range of temperatures.

Also injection moldable materials are a plus.

Any suggestions?

Thanks for the help

From your very limited information, I would guess black plastic would be fine...

Otherwise, injection mouldable MoS2 filled nylons are such as Nylatron (Google for), and I guess there are many others. btw, MoS2 nylons are very difficult to dry as MoS2 is very hygroscopic. Need Vacuum or desiccant dryer.

Cheers

Yes, as Pud says there are many lubricated nylon grades. You can find them at the place you yourself mentioned.

I just had a look and found many grades of nylon 6 filled with PTFE, oil, MoS2. You may also find it with graphite as filler.

There was some very good information available from LNP and DSM and I think RTP about bearing and friction properties of nylons.

It is very dependant on specific details of the application. The information you provided falls far short of what is required for a reasonable suggestion.

The information on Nyloil is a bit doubtful re melting temp and moisture absorption. I don't have time to research in detail to determine the nylon type, but if you can find a match for both melting point and moisture absorption, it should be the same type.

Cast nylons have a better impact strength than injection moulded parts with similar other properties.
