全氟烷氧基树脂 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 PTFE和FEP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PTEF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。PFA(可溶性聚四氟乙烯〕耐热、耐寒、化学稳定性、机械性、绝缘性、自润滑性、耐折性、耐开裂性优异。公司开发有注塑、挤出,模压料。2. 适用范围:目前国内主要用于防腐防酸碱注塑件、高温电线电缆、防酸碱内衬件,吹塑制品等。技术参数:比重(g/CM3)2.12-2.17

For inventory control purposes product name may be followed by an X. Products labeled PFA TE9724 and PFA TE9724 X are equivalent and all information in this document is applicable to both. Typical Application DuPont™ Teflon ® PFA TE9724 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 compression molded articles requiring superior electrical, chemical, and thermal properties. Teflon ® PFA TE9724 offers a slightly higher melt flow rate than Teflon ® PFA TE9725, providing greater processing ease. Description DuPont™ Teflon ® PFA TE9724 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 high 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 TE9724. Teflon ® PFA TE9724 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 TE9724 can be used to improve processing rates. Compared with other thermoplastics, Teflon ® PFA TE9724 provides a superior balance and level of end-use properties at high service temperatures. Teflon ® PFA TE9724 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene. Properly processed products made from neat Teflon ® PFA TE9724 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 TE9724 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 TE9724 meets the requirements of ASTM D3307, Type I | ||||
