My intentions is not to start an argument but I have a hard time not speaking up.
We have been selling Graphite Impregnated Poly for years (29 years) so there are a few things in his info that I would have to argue.
WRONG #1 You cannot blend anything into Polyurethane.
Not even Graphite!
Nothing like this works because the family of Urethane
plastic does not like impurities.
(the word Polyurethane means blends of different Urethane plastics)
If you do a cross section of any of our Polygraphite Bushings you can clearly see the graphite.
Graphite does not work for a couple reasons. If you put just a little in
the Urethane then the graphite is fully encapsulated by the Urethane
and the Graphite never touches the metal sway bar or a-arm shaft.
If you add a lot,
then the Polyurethane falls apart because
it does not stick to the graphite (remember, graphite is a slippery lubricant).
You might as well throw handful of dirt into it.
Secondly we have had no issues with bushings crumpling in 29 years
I am all for the small guy and their business, but I not for miss leading information.
Thanks
James
