杜邦特氟隆聚四氟乙烯62X是一种聚四氟乙烯细粉末树脂,主要用于膏体挤出。特氟隆聚四氟乙烯62X提供了特氟隆氟聚合物树脂典型特性的优良组合:无老化特性;几乎对所有工业化学品和溶剂的化学惰性;优异的介电性能,频率和温度稳定;韧性和柔韧性;低摩擦系数;不粘炭特性学;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,Teflon® PTFE 62 X是一种高级树脂,具有增加的热稳定性、优越的弯曲寿命、优越的应力开裂阻力、低渗透性和高清晰度。Teflon® PTFE 62 X设计用于在100:1到600:1的中高还原比下进行加工。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。Teflon® PTFE 62 X满足以下要求:ASTM D4895-10,I型,4级,B类典型应用Teflon® PTFE 62 X主要用于安装在要求较高的应用中的管道。它包括高性能产品,如增强软管,要求在与液压流体、碳氢燃料或活性气体一起使用的化学、制药和汽车工业中具有最高的可靠性和性能。例如,这种应用是燃料组件和制动系统的超负荷软管。 DuPont ™ Teflon ® PTFE 62 X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ® PTFE 62 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 62 X is a premium resin that has increased thermal stability, superior flex life, superior stress crack resistance, low permeability and high clarity. Teflon® PTFE 62 X is designed for processing at medium to high reduction ratios of 100:1 to 600:1. 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 molding and convoluting. Teflon® PTFE 62 X meets the following requirements: ASTM D4895-10, Type I, Grade 4, Class B Typical Applications Teflon® PTFE 62 X is mainly used for tubing installed in demanding applications. It includes high performance articles such as reinforced hose requiring the ultimate in reliability and performance in chemical, pharmaceutical and automotive industry in use with hydraulic fluid, hydrocarbon fuel or reactive gas. Such applications are for example overbraided hoses for fuel assemblies and brake systems. |
