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的產品形式有用于模塑和擠塑的粒狀產品,用于旋轉模塑和涂料的粉狀產品;其半成品有膜、板、棒和管材。美國市場經銷的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、化學穩定性、機械性、絕緣性、自潤滑性、耐折性、耐開裂性優異。公司開發有注塑、擠出,模壓料。2. 適用范圍:目前國內主要用于防腐防酸堿注塑件、高溫電線電纜、防酸堿內襯件,吹塑制品等。技術參數:比重(g/CM3)2.12-2.17

For inventory control purposes product name may be followed by an X. Products labeled PFA TE9725 and PFA TE9725 X are equivalent and all information in this document is applicable to both. Typical Application DuPont™ Teflon ® PFA TE9725 is an ideal resin for applications involving compounding and compression molding, as well as extruded tubing and other profiles for hose, electrical insulators, and sleeving; industrial film and products made from film; and injection or blow-molded articles requiring superior electrical, chemical, and thermal properties. Teflon ® PFA TE9725 offers a slightly lower melt flow rate than Teflon ® PFA TE9724, ultimay providing a higher degree of stress-crack resistance. Description DuPont™ Teflon ® PFA TE9725 is a general purpose fluoroplastic resin available as loosely compacted fluff. It is intended for use in special application processes in consultation with DuPont. Compared with other grades of Teflon ® PFA, its most unique features are a relatively low flow rate and properties that make it suitable for a variety of processes and demanding end uses, especially compounding and compression molding. Table 1 shows the typical property data for Teflon ® PFA TE9725. Teflon ® PFA TE9725 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 TE9725 can be used to improve processing rates. Compared with other thermoplastics, Teflon ® PFA TE9725 provides a superior balance and level of end-use properties at high service temperatures. Teflon ® PFA TE9725 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene. Properly processed products made from neat Teflon ® PFA TE9725 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 TE9725 resist ignition and do not promote flame spread. When ignited by flame from other sources, their contribution of heat is very small and dded at a slow rate with very little smoke. Teflon ® PFA TE9725 meets the requirements of ASTM D3307, Type II | ||||
