How to produce PTFE Dispersions

My question is rather simple. I have PTFE powder in the lab. How to make a stable aqueous or oil dispersion of the same PTFE in water or oil, as PTFE is highly hydrophobic and is not responding to either water or oil.

Buy a commercial pack like from an EN vendor. It has a proper wetting agent and a proper size teflon particle to allow the teflon to go into a suspension. It requires agitation and it will drop out and not go back into a suspension after a given period of setting for that product.
