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.
The Teflon® FEP resin in Teflon® 121A is a true thermoplastic, providing superior properties typical of the fluoropolymer resins: retention of properties after service at 204°C (400°F), useful properties at –240°C (–400°F), chemical inertness to nearly all industrial chemicals and solvents, and excellent dielectric properties. Refer to Table 1 for typical property data.
Applications
Teflon® FEP 121A is suitable for many end products, including: heat-sealable top coatings for PTFE-coated fabrics used for belting, circuit boards, or electrical insulation; cast film for capacitors or chemical barriers; and as a hot melt adhesive for bonding molded PTFE or FEP parts to themselves or to each other.

FEP是四氟乙烯和六氟丙烯共聚而成，又叫聚全氟乙丙烯共聚物。
FEP结晶熔化点为580 ℉ ，密度为2.15g／CC（克／立方厘米），它是一种软性塑料，其拉伸强度、耐磨性、抗蠕变性低于许多工程塑料。它是化学惰性的，在很宽的温度和频率范围内具有较低的介电常数（2.1）。该材料不引燃，可阻止火焰的扩散。它具有优良的耐候性，摩擦系数较低，从低温到392 ℉ 均可使用。该材料可制成用于挤塑和模塑的粒状产品，用作流化床和静电涂饰的粉末，也可制成水分散液。半成品有膜、板。棒和单纤维。其主要的用途是用于制作管和化学设备的内村、滚筒的面层及各种电线和电缆，如飞机挂钩线、增压电缆、报警电缆、扁形电缆和油井测井电缆。FEP膜已见用作太阳能收集器的薄涂层。
