The difference between the two is PTFE stands for Poly Tetra Fluoro Ethylene, which is DuPont's Teflon. TFE is Tetra Fluoro Ethylene, which is an odorless, tasteless gas and is deadly.
PTFE does not have it's own recycling code symbol. However, PTFE can be recycled into many other products. Recycled PTFE can be used for rods, tubing, tape and more

PTFE stands for polytetrafluoroethylene. Teflon is the registered trade mark for this, and is owned by DuPont.

There is no evidence of a ball been made from polyurethane. There are polyurethane foam balls, but unfortunately no tennis balls. The process is likely to be the same as a normal tennis ball, the only difference being that the rubber in the ball is replaced by polyurethane.
Polyurethane isn't epoxy, but they're both resins. They're also both reaction copolymers--you get either one through a chemical reaction between two components. The difference is, epoxy contains epoxide and polyamine; polyurethane contains a complex alcohol (either a "diol" or a "polyol") plus an isocyanate.
This means a thin layer of plastic is stuck onto some fabric or cloth.It could be made into a raincoat for example. Like GorTex.As for using it 'on its own', not sure what you mean.-edit-Whoops, I see you clarified PTFE (Teflon) as the laminate. Its too soft to hold a shape so its stuck onto the inside of 'non-stick' pots and pans.
PTFE is not biodegradable. It can be degraded by pyrolysis or radiation.
