全氟烷氧基樹脂 PFA樹脂相對來說是比較新的可熔融加工的氟塑料。 PFA的熔點大約為580F,密度為2.13— 2.16g/cc(克/立方厘米)。PFA與 PTFE和FEP相似,但在302T以上時,機械性能略優(yōu)于FEP,且可在高達500F下的溫度下使用,它的耐化學品性與PTEF相當。PFA的產(chǎn)品形式有用于模塑和擠塑的粒狀產(chǎn)品,用于旋轉(zhuǎn)模塑和涂料的粉狀產(chǎn)品;其半成品有膜、板、棒和管材。美國市場經(jīng)銷的PFA樹脂有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的用途與FEP類似。PFA(可溶性聚四氟乙烯〕耐熱、耐寒、化學穩(wěn)定性、機械性、絕緣性、自潤滑性、耐折性、耐開裂性優(yōu)異。公司開發(fā)有注塑、擠出,模壓料。2. 適用范圍:目前國內(nèi)主要用于防腐防酸堿注塑件、高溫電線電纜、防酸堿內(nèi)襯件,吹塑制品等。技術(shù)參數(shù):比重(g/CM3)2.12-2.17

| For inventory control purposes product name may be followed by an X. Products labeled PFA 350 and PFA 350 X are equivalent and all information in this document is applicable to both. Typical Application Applications for DuPont™ Teflon ® PFA 350 include extruded tubing for use in handling aggressive fluids at high pressures; chemical linings for pipes used in the chemical processing industry; film for high flex service; and traditional extruded, injection-molded, or blow-molded articles requiring the unique performance of Teflon ® . Description DuPont™ Teflon ® PFA 350 is a general-purpose fluoroplastic resin available in pellet form. Compared with other grades of Teflon ® PFA, its most unique features are a relatively low flow rate, greatly increased flex life, and enhanced resistance to environmental stress-cracking over both Teflon ® PFA 340 and 345 (Teflon ® PFA 350 has a typical MIT folding endurance of 500,000*, compared to that of 15,000 and 50,000 for Teflon ® PFA 340 and 345 respectively). Teflon ® PFA 350 is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Table 1 shows the typical property data for Teflon ® PFA 350. Teflon ® PFA 350 is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoroplastic resin. Compared to other thermoplastics, the high melt strength and thermal stability of Teflon ® PFA 350 can be used to improve processing rates. Compared with other fluoroplastics, creep resistance at high service temperatures provides a superior balance and level of end-use properties. Teflon ® PFA 350 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene. Properly processed products made from neat Teflon ® PFA 350 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 350 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 350 meets the requirements of ASTM D3307, Type III | ||||
