Traction coefficiant

[chillzilla]

Can someone tell me what traction co-efficiant means in relation to refrigerant oils ?

[knighty]

I'm not a RE.....

but in plain english....

it's how hard it is to pull the oil appart / how well it's stuck together..

something with a low traction co-efficiant will form very small dropletswhen spilt

something with a high traction co-efficiant will form larger droplets when spilt

it's also relevent when running over gears .. how much oil they pick up etc..

I (guess) it would effect oil return to the compressor too ? larger droplets will be easier to return than smaller ones ?

I am picking it is "miscability" [ spell check required . ]. But I have been wrong before.
