    ??聚四氟乙烯生料帶(PTFE生料帶)是在壓縮力作用下,樹(shù)脂產(chǎn)生的剩余變形,利用推壓成型方法先制成棒材或帶材,再將其放在輥壓機(jī)上滾壓,在輥筒壓力作用下,便展延成為有一定厚度和寬度的薄帶,最后除去助擠劑而得到生料帶。

    ??聚四氟乙烯生料帶(PTFE生料帶)是一種耐腐蝕、耐高溫的優(yōu)良密封材料,可用于水管、腐蝕性流體輸送管材、蒸氣管路接頭的密封材料。

    絕緣性:不受環(huán)境及頻率的影響,體積電阻可達(dá)1018歐姆·厘米,介質(zhì)損耗小,擊穿電壓高。

    耐高低溫性:對(duì)溫度的影響變化不大,溫域范圍廣,可使用溫度-190~260℃。

    自潤(rùn)滑性:具有塑料中最小的摩擦系數(shù),是理想的無(wú)油潤(rùn)滑材料。

    表面不粘性:已知的固體材料都不能粘附在表面上,是一種表面能最小的固體材料。

    耐大氣老化性,耐輻照性能和較低的滲透性:長(zhǎng)期暴露于大氣中,表面及性能保持不變。

    不燃性:限氧指數(shù)在90以下。
