PEEK 又名:聚醚醚酮 板材, 棒材: ¢5~ ¢80㎜*1000㎜ 用途: 活塞密封墊圈、滑動軸承、閥門座、軸承套、嵌齒輪、插頭連接、密封圈。特點: 非常高的拉力及彎曲強度/剛性/硬度,高尺寸安定性。沖擊韌性高且具均衡的電氣性質,非常良好的滑動性,高抗化/抗輻射性,高抗水解性,高溫抗熱穩定性可達到﹢270℃,C.UL驗示在﹢250℃高溫負荷下其抗水解性仍極優,難燃自熄性。 缺點:不耐沖擊,不耐濃硫酸或氧化劑,如濃硝酸或含水氯。聚醚醚酮(PEEK)材料的卓越性能主要表現在以下幾方面:1耐高溫PEEK具有較高的玻璃化轉變溫度和熔點(334℃),這是它可在有耐熱性要求的用途中可靠應用的理由之一。其負載熱變型溫度高達316℃,連續使用溫度為260℃。1機械特性PEEK是韌性和剛性兼備并取得平衡的塑料。特別是它對交變應力的優良耐疲勞是所有塑料中最出眾的,可與合金材料媲美。2自潤滑性PEEK在所有塑料中具有出眾的滑動特性,適合于嚴格要求低摩擦系數和耐摩耗用途使用。特別是碳纖、石墨各占一定比例混合改性的PEEK自潤滑性能更佳。3耐化學藥品性(耐腐蝕性)PEEK具有優異的耐化學藥品性.在通常的化學藥品中,能溶解或者破壞它的只有濃硫酸,它的耐腐蝕性與鎳鋼相近。4阻燃性PEEK是非常穩定的聚合物,1.45mm厚的樣品,不加任何阻燃劑就可達到最高阻燃標準。5耐剝離性PEEK的耐剝離性很好,因此可制成包覆很薄的電線或電磁線,并可在苛刻條件下使用。6耐疲勞性PEEK在所有樹脂中具有最好的耐疲勞性。7耐輻照性耐高輻照的能力很強,超過了通用樹脂中耐輻照性最好的聚苯乙烯。可以作成γ輻照劑量達1100Mrad時仍能保持良好的絕緣能力的高性能電線。8耐水解性PEEK及其復合材料不受水和高壓水蒸氣的化學影響,用這種材料作成的制品在高溫高壓水中連續使用仍可保持優異特性。
