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。表現(xiàn)出較高的透明度，較低的熔融粘度，化學(xué)穩(wěn)定性，反應(yīng)性低，對熱，化學(xué)物質(zhì)，滲透性，天氣和紫外線的耐藥性極佳。具有低介電常數(shù)，耗散因子，良好的拉伸強(qiáng)度，高頻率和溫度范圍內(nèi)的高介電強(qiáng)度。提供低臨界表面能和非常低的光反射。適用于注射和擠出過程。建議用于電線絕緣，容器，試管，電動和電子零件。
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。盡管沒有像PTFE，F(xiàn)EP和PFA那樣完全氟化，但ETFE維持許多高溫特征，例如高溫（連續(xù)使用溫度為150度C），20年的風(fēng)化，非常好的電氣性能和非常好的化學(xué)惰性。而且，與完全氟化的產(chǎn)品相比，ETFE更堅硬，更具耐磨性，使其非常適合苛刻的應(yīng)用，例如石油和天然氣下孔電纜和臍帶，低滲透性汽車燃料管，航空航天線和電纜，以及光伏的上衣薄膜。 ETFE還廣泛用于用于制造碳纖維復(fù)合材料的釋放膜。 ETFE是融化的，Daikin為您提供一系列熔體流量指數(shù)以適合您的制造過程。Daikin還制作了可以粘附到多酰胺進(jìn)行多層管的ETFE，而無需使用粘合劑或扎帶層。
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.
