| 杜邦Tefzel 2195含氟聚合物是一种高级树脂，设计用于旋转成型。作为一种有效的旋转成型树脂，Tefzel2195是一种自由流动的粉末，具有可控的粒径、形状和尺寸分布。Tefzel 2195的成型性能与其他等级的Tefzel含氟树脂相似。旋转成型是制造空心零件（特别是大型零件）或具有复杂几何形状的零件的常用工艺。根据零件设计和加工条件，Tefzel 2195也可用于旋转线项目，从而Tefzel与零件内表面结合形成衬里。由Tefzel 2195制成的经适当处理的旋转模制品具有典型的氟聚合物树脂的优良性能：在150°C（302°F）下使用后保持性能，在-100°C（-148°F）下保持有用性能，以及对大多数工业化学品和溶剂的化学惰性。模制品具有优良的刚度和高的极限伸长。与火焰情况下的行为相关的声明或数据不旨在反映实际火灾条件下该材料或任何其他材料所带来的危险。典型的终端产品Tefzel 2195非常适合用于化学加工行业的流体处理的许多终端产品，包括泵壳、容器、柱、弯管、三通和具有不寻常形状的管段。此外，任何内部轮廓允许粉末流均匀涂层的中空结构都是衬里的候选材料，前提是它能够承受高温。 DuPont™ Tefzel ® 2195 fluoropolymer is a premium-grade resin designed for use in rotational molding. To be effective as a rotational molding resin, Tefzel ® 2195 is a free-flowing powder, with controlled particle size, shape, and size distribution. The properties of Tefzel ® 2195 in molded form are similar to other grades of Tefzel ® fluoropolymer resin. Rotational molding is a favored process for making hollow parts (particularly large parts) or for parts with complex geometries. Depending on part design and processing conditions, Tefzel ® 2195 can also be used to rotoline items, whereby the Tefzel® binds to the inner surface of the part to form a lining. Properly processed rotational moldings made from Tefzel ® 2195 provide the superior properties typical of the fluoropolymer resins: retention of properties after service at 150°C (302°F), useful properties at -100°C (-148°F), and chemical inertness to most industrial chemicals and solvents. Molded products have excellent stiffness and high ultimate elongation. Statements, or data, regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions. Typical End Products Tefzel ® 2195 is ideal for many end products for fluid handling in the chemical processing industries, including pump housings, vessels, columns, elbows, tees, and pipe sections with unusual shapes. In addition, any hollow structure with internal contours that permits uniform coating by powder flow is a candidate for lining, provided it can withstand high temperatures. |

| 2 The upper service temperature is based on heat-aging tests and represents the temperature at which tensile strength and elongation would be expected to be diminished 50% after 10,000 hr thermal aging. Upper service temperatures above 150°C (302°F) may be feasible, depending on such factors as chemical exposure and support from the substrate. Particularly when considering uses of Tefzel ® 2195 above 150°C (302°F), perform preliminary testing to verify the acceptability. |
