?ETFE膜材料將用于2008北京奧林匹克國家體育場和國家游泳中心等場館。那么ETFE是一種材料嗎?ETFE的英文名稱:ethylene-tetra-fluoro-ethylene,中文全稱:乙烯-四氟乙烯共聚物,ETFE是一種堅韌的材料,各種機械性能均衡良好-極強的抗撕裂性,高抗拉強度,中等硬度,優異的抗沖擊性和長壽命。ETFE是一種良好的介電材料,具有高介電強度,介電常數為2.6,高電阻率和低損耗因子僅為0.003。在頻率和溫度變化的情況下,其低介電常數基本恒定。
ETFE的工作溫度范圍更實用。恒溫通常設定在-65°C至+150°C之間。在超低溫下仍然很硬,其脆化溫度低至-100°C。此外,ETFE已通過多項嚴格的耐火測試,并達到UL94V-0等級。它對大多數化學品的物理性質和對普通氣體和水分的低滲透性幾乎沒有影響。
什么是ETFE導電塑料?導電ETFE塑料是結晶聚合物,熔點為256-280°C。它可以在燃燒時自熄。其抗剪切機械強度高,其低溫抗沖擊性能是現有氟塑料中最好的。它具有從室溫到-80°C的高沖擊強度,穩定的化學性質,良好的電絕緣性和抗輻射性。。ETFE薄膜的實際應用始于20世紀90年代,主要作為農業溫室的覆蓋材料,以及各種形狀建筑物的遮陽篷材料,如體育場看臺,建筑錐頂,賭場,旋轉餐廳檐篷,娛樂廳遮陽篷。封面,停車場,展覽廳和博物館。
杜邦的導電ETFE塑料和朝日玻璃有限公司,主要用于防腐襯里。該材料具有聚四氟乙烯的耐腐蝕性,并且具有金屬特有的強粘合性能,克服了聚四氟乙烯與金屬不粘附的缺點,其平均線膨脹系數接近于碳鋼。膨脹系數使ETFE成為理想的金屬復合材料,具有優異的耐負壓性。 。以上文獻若需轉載請備注出處:PBT樹脂 //shanglikaiguan.cn/
