杜邦Teflon® PTFE 62XT X是一种主要用于膏体挤出的聚四氟乙烯细粉末树脂。特氟隆聚四氟乙烯62xt x提供了特氟隆氟聚合物树脂的典型性能组合:无老化特性;几乎对所有工业化学品和溶剂的化学惰性;特殊的介电性能,频率和温度稳定;韧性和柔韧性;低摩擦系数;不粘分形学;可忽略的吸湿性;优异的耐候性;工作温度高达260°C(500°F);在-240°C(-400°F)下的有用特性;中等硬度和高极限延伸率。与其他等级的聚四氟乙烯细粉相比,聚四氟乙烯62xt x是一种高级树脂,具有提高的热稳定性、优越的弯曲寿命、优越的应力抗裂性、低渗透性和高清晰度。特氟隆聚四氟乙烯62xt x设计用于中高还原率为400:1至1600:1的加工。特别适用于生产优质管材、意大利面管材和金属丝涂层。这一等级也非常适合后处理技术,如翻边,焊接,吹塑和卷积。特氟隆聚四氟乙烯62xt x满足以下要求:ASTM D4895-10,I型,3级,D类典型应用特氟隆聚四氟乙烯62xt x主要用于生产安装在要求最终可靠性和性能的应用中的管道。在需要接触液压流体、碳氢燃料或反应性气体的化学、制药和汽车工业中有应用。其中一个应用是热交换器中的高压管道。 DuPont ™ Teflon® PTFE 62XT X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ® PTFE 62XT X offers the excellent combination of properties typical of the Teflon® fluoropolymer resins: non-aging characteristics; chemical inertness to nearly all industrial chemicals and solvents; exceptional dielectric properties, stable with frequency and temperature; toughness and flexibility; low coefficient of friction; non-stick characteristics; negligible moisture absorption; excellent weather resistance; service temperature up to 260 °C (500°F); useful properties at -240°C (-400°F); moderate stiffness and high ultimate elongation. Compared with other grades of PTFE fine powder, Teflon ® PTFE 62XT X is a premium resin that has increased thermal stability, superior flex life, superior stress crack resistance, low permeability and high clarity. Teflon ® PTFE 62XT X is designed for processing at medium to high reduction ratios of 400:1 to 1600:1. It is particularly suitable for production of high quality tubing, spaghetti tubing and wire coating. This grade is also highly suitable for after-processing technologies such as flanging, welding, blow moulding and convoluting. Teflon ® PTFE 62XT X meets the following requirements: ASTM D4895-10, Type I, Grade 3, Class D Typical Applications Teflon ® PTFE 62XT X is used primarily in the production of tubing installed in applications requiring the ultimate in reliability and performance. Applications are found in the chemical, pharmaceutical, and automotive industries where contact with hydraulic fluid, hydrocarbon fuel or reactive gases is required. One such application is high pressure tubing in heat exchangers. |
