    产品说明:
    For inventory control purposes product name may be followed by an X.

    Products labeled PFA 440HPA and PFA 440HPA X are equivalent and all information in this document is applicable to both.

    Typical Application
    Applications for DuPont™ Teflon ® PFA 440HPA include fluid handling components for critical, high-purity processes like semiconductor, pharmaceutical, and biotechnology, as well as applications where purity in the parts-per-billion range is needed. Teflon ® PFA 440HPA offers a slightly higher melt flow rate than Teflon ® PFA 440HPB, providing greater processing ease.

    Description
    DuPont™ Teflon ® PFA 440HPA is a special purpose fluoroplastic resin available in pellet form. This resin is a chemically modified form of Teflon ® PFA 340 that combines many of the benefits of the parent resin (a relatively high typical melt flow rate of 16) with several additional benefits including enhanced purity, improved thermal stability while processing, and chemical inertness, for example, to ozonated fluids. Table 1 shows the typical property data for Teflon ® PFA 440HPA.

    Teflon ® PFA 440HPA is a premium resin with the lowest level of extractables designed to meet ultra-high purity requirements. Teflon ® PFA 440HPA has a relatively high melt flow rate (typical MFR of 16) for injection molding and extrusion processes, and the highest level of inertness due to stable end group polymer structure. The enhanced purity of Teflon ® PFA 440HPA makes it suitable for applications that require improved color, lower extractable fluorides, and freedom from other foreign materials. This product contains no additives and is designed for hostile chemical environments where purity in the parts-per-billion range is needed. Examples are in semiconductor manufacture, fluid handling systems for industry or life sciences, and instrumentation for precise measurements of fluid systems. Compared to other thermoplastics, the high melt strength and thermal stability of Teflon ® PFA 440HPA can be used to improve processing rates, combining the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.

    Properly processed products made from neat Teflon ® PFA 440HPA resin provide the superior properties characteristic of fluoroplastic resins: chemical inertness, exceptional dielectric properties, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes, and excellent weather resistance.

    In a flame situation, products of Teflon ® PFA 440HPA resist ignition and do not promote flame spread. When ignited by flame from other sources, their contribution of heat is very small and added at a slow rate with very little smoke.

    Teflon ® PFA 440HPA meets the requirements of ASTM D3307, Type I

    1、 为少量全氟丙基全氟乙烯基醚与聚四氟乙烯的共聚物。熔融粘结性增强,溶体粘度下降,而性能与聚四氟乙烯相比无变化。此种树脂可以直接采用普通热塑性成型方法加工成制品。
    2、长期使用温度-196--260摄氏度,有卓越的耐化学腐蚀性,对所有化学品都耐腐蚀,摩擦系数在塑料中*低,还有很好的电性能,其电绝缘性不受温度影响,有“塑料王”之称。
    3、其耐化学药品性与聚四氟乙烯相似,比偏氟乙烯好。
    4、其抗蠕变性压缩强度均比聚四氟乙烯好,拉伸强度高,伸长率可达100-300%。介电性好,耐辐射性能优异。阻燃性达V0级。
    5、适于制作耐腐蚀件,减磨耐磨件、密封件、绝缘件零件。
    6、高温电线、电缆绝缘层,防腐设备、密封材料泵阀衬套,和化学容器。
    成型性能
    1.结晶料,吸湿小。可采用通常得热塑性塑料得加工方法加工成制品。
    2.流动性差,极易分解,分解时产生腐蚀气体。宜严格控制成型温度不要超过475摄氏度,模具应加热至150-200摄氏度,浇注系统对料流阻力应小。
    3.半透明粒料,注塑、挤出成型。成型温度350-400摄氏度,475摄氏度以上容易引起变色或发生气泡。并注意脱模会较困难。
    4、因熔融的材料对金属有腐蚀作用,长期生产,模具需要电镀铬处理。
    氟烷氧基树脂
    PFA树脂相对来说是比较新的可熔融加工的氟塑料
    PFA的熔点大约为580F,密度为2.13— 2.16g/cc(克/立方厘米)。PFA与 PTFEFEP相似,但在302T以上时,机械性能略优于FEP,且可在高达500F下的温度下使用,它的耐化学品性与PTFE相当。PFA的产品形式有用于模塑和挤塑的粒状产品,用于旋转模塑和涂料的粉状产品;其半成品有膜、板、棒和管材。美国市场经销的PFA树脂有DUPOut公司的Teflon牌、Daikin公司的Neoflon牌、Ansimont公司的Hthen牌、HOechst Celanese公司的 Hostafl牌。PFA的用途与FEP类似。
