 |
Teflon FEP 121A fluoropolymer resin(formerly called TE-9535) is a colloid containing approximately 54%(by total weight) of 0.1 to 0.30 mm fluorinated ethylene propylene(FEP)particles suspended in water.
It also contains approximately 6%(by weight of FEP resin) of volatile, nonionic, and anionic wetting agents.
Color is off-white and nominal pH is 9.5.
Viscosity at room temperature is approximately 25 cP.
Teflon 121A is a general-purpose dispersion.
It can be used to impart some of the unique properties of Teflon FEP resin to end products that would be difficult to make using traditional melt extrusion processes.
It can be used to coat or impregnate porous structures or to make thin films.
It can be coated and melt bonded to polytetrafluoroethylene(PTFE) resin or used as a hot melt adhesive.
Teflon FEP 121A is an improved version of Teflon FEP 120.
It utilizes the same base resin as Teflon FEP 120 and has the same excellent wetting characteristics.
It has been improved to reduce the rate of sedimentation and thus prolong the storage life. |
