说明杜邦特氟隆FEP TE-9568含氟聚合物树脂是一种带负电荷的疏水性胶体,含有悬浮在水中的约54%(按总重量计)的0.1至0.30微米氟化乙烯丙烯(FEP)颗粒。它还含有大约6%(按重量计的FEP树脂)的非离子润湿剂和稳定剂。颜色为灰白色,标称pH值为10.0。室温下的粘度约为25 cp。特氟隆TE-9568是一种通用分散剂。它可用于将特氟隆FEP树脂的一些独特特性传授给使用传统熔融挤压工艺难以制造的最终产品。它可以用来覆盖或浸渍多孔结构或使其变薄?LMS。它可以被涂上并熔化粘合到聚四氟乙烯(PTFE)树脂上,或者用作热熔粘合剂。TE-9568中的特氟隆FEP树脂是一种真正的热塑性塑料,具有典型的氟聚合物树脂的优良性能:在204°C(400°F)下使用后的性能保持,在-240°C(-400°F)下的有用性能,对几乎所有工业化学品和溶剂的化学惰性,以及优良的介电性能。典型性能数据见表1。典型的终端产品特氟隆FEP TE-9568适用于许多终端产品,包括:用于皮带、电路板或电气绝缘的聚四氟乙烯涂层织物的热密封面涂层;用于电容器或化学屏障的铸膜;以及用于将成型的聚四氟乙烯或FEP零件粘在一起或彼此之间的热熔粘合剂。 Description DuPont™ Teflon ® FEP TE-9568 fluoropolymer resin is a negatively charged, hydrophobic colloid containing approximately 54% (by total weight) of 0.1 to 0.30 µm fluorinated ethylene propylene (FEP) particles suspended in water. It also contains approximately 6% (by weight of FEP resin) of a nonionic wetting agent and stabilizer. Color is off-white and nominal pH is 10.0. Viscosity at room temperature is approximately 25 cP. Teflon ® TE-9568 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 difflcult to make using traditional melt extrusion processes. It can be used to coat or impregnate porous structures or to make thin ?lms. It can be coated and melt bonded to polytetrafluoroethylene (PTFE) resin or used as a hot melt adhesive. The Teflon ® FEP resin in TE-9568 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. Typical End Products Teflon ® FEP TE-9568 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. |
