I've come up with a haphazard design for grenades that coat their surroundings with slippery polytetrafluoroethylene when they explode, the purpose being an area denial weapon. If someone is chasing you, toss it behind you and your pursuer will either have to slow down to avoid falling, or fall flat on their ass if they don't take their time and slowly navigate the area covered in polytetrafluoroethylene. It could also be used to slow down people attempting to charge you in a gunfight since they'll have to concentrate on maneuvering cautiously while also firing their guns and making sure not to get shot themselves.
However, I'm no chemistry buff. From what I've gathered from internet research, polytetrafluoroethylene (which will be called PTFE from now on) cannot exist as a liquid and behave like it does as a solid. Instead of being a slippery liquid, it will be a horribly toxic powder. In order for my grenades to properly spread PTFE around the combat environment it would seem it would have to be PTFE powder suspended in some sort of solution within the grenade. The question, is what solution would be the most proper for containing the PTFE, and what processes would be necessary to cause the canister to launch PTFE in a 360 degree radius around it. The grenade would have a pin, and once the pin is pulled the countdown till the non-lethal PTFE explosion goes off would begin.
