NEOFLON™ ETFE EP-521 Daikin 日本大金四氟乙烯（TFE）和乙烯的共聚物
Daikin的Neoflon™ETFE EP-521是四氟乙烯（TFE）和乙烯的共聚物。表现出较高的透明度，较低的熔融粘度，化学稳定性，反应性低，对热，化学物质，渗透性，天气和紫外线的耐药性极佳。具有低介电常数，耗散因子，良好的拉伸强度，高频率和温度范围内的高介电强度。提供低临界表面能和非常低的光反射。适用于注射和挤出过程。建议用于电线绝缘，容器，试管，电动和电子零件。
NEOFLON™ ETFE EP-521 by Daikin is a copolymer of tetrafluoroethylene (TFE) and ethylene. Exhibits high transparency, lower melt viscosity, chemical stability, low reactivity, excellent resistance to heat-, chemicals-, permeation-, weather- and UV. Possesses low dielectric constant, dissipation factor, good tensile strength, high dielectric strength over a wide range of frequencies and temperatures. Offers the low critical surface energy and very low light reflection. Suitable for injection and extrusion processes. Recommended for wire insulation, containers, tubes, electric- and electronic parts. NEOFLON™ ETFE EP-521 complies with FDA 21 CFR.177.1550, ISO-9001 (Quality System), ISO-14001 (Environmental System) and Responsible Care 14001 (Safety, Health, Environment and Security).
Daikin Etfe是乙烯和四氟乙烯的交替共聚物。尽管没有像PTFE，FEP和PFA那样完全氟化，但ETFE维持许多高温特征，例如高温（连续使用温度为150度C），20年的风化，非常好的电气性能和非常好的化学惰性。而且，与完全氟化的产品相比，ETFE更坚硬，更具耐磨性，使其非常适合苛刻的应用，例如石油和天然气下孔电缆和脐带，低渗透性汽车燃料管，航空航天线和电缆，以及光伏的上衣薄膜。 ETFE还广泛用于用于制造碳纤维复合材料的释放膜。 ETFE是融化的，Daikin为您提供一系列熔体流量指数以适合您的制造过程。Daikin还制作了可以粘附到多酰胺进行多层管的ETFE，而无需使用粘合剂或扎带层。
Daikin ETFE is an alternating copolymer of ethylene and tetrafluoroethylene. Although not fully fluorinated like PTFE, FEP and PFA, ETFE maintains many of the high performance characteristics such has high temperature (continuous service temperature of 150 Deg C), 20-year weathering, very good electrical properties, and very good chemical inertness. And, ETFE is tougher and more abrasion resistant than the fully fluorinated products, making it ideally suited for demanding applications such as oil and gas down hole cable and umbilicals, low permeation automotive fuel tubing, aerospace wire and cable, and photovoltaic top sheets films. ETFE is also widely used for release films used in the manufacture of carbon fiber composites. ETFE is melt processible and Daikin provides grades with a range of melt flow index to suit your manufacturing process. Daikin also makes ETFE that can be adhered to polyamide for multilayer tubing without the use of adhesive or tie layer.
Fluoropolymers are widely used in automotives, aerospace, semiconductors, electronics and common household appliances because of their unique non-adhesive and low friction properties as well as their superior heat, chemical and weather resistance and superior electrical properties compared with the other polymers.
