它是由四氟乙烯经聚合而成的高分子化合物,其结构简式为 -[-CF2-CF2-]n- ,具有优良的化学稳定性、耐腐蚀性(聚四氟乙烯简称PTFE或F4,是当今世界最耐腐蚀的材料之一,“塑料王”是聚四氟乙烯的俗称,它是一种耐腐蚀性最好的塑料。它不受已知的酸、碱、盐、氧化剂的腐蚀,就是王水也对它无可奈何,因此得名塑料王,除熔融金属钠和液氟外,能耐其它一切化学药品,广泛应用于各种需要抗酸碱和有机溶剂的、密封性、高润滑不粘性、电绝缘性和良好的抗老化耐力、耐温优异(能在250℃至-180℃的温度下长期工作)。氟乙
温度 -20~250℃(-4~482°F),允许骤冷骤热,或冷热交替操作。
压力 -0.1~6.4Mpa(全负压至64kgf/cm2)(Full vacuum to 64kgf/cm2)
它的产生解决了我国化工、石油、制药等领域的许多问题。聚四氟乙烯密封件、垫圈、垫片 聚四氟乙烯密封件、密封垫圈是选用悬浮聚合聚四氟乙烯树脂模塑加工制成。聚四氟乙烯与其他塑料相比具有耐化学腐蚀的特点,它已被广泛地应用作为密封材料和填充材料。
其在500摄氏度左右的完全热分解产物有四氟乙烯、六氟丙烯和八氟环丁烷,这些产物在高温时会分解出高腐蚀性的含氟气体。
各类聚四氟乙烯制品已在化工、机械、电子、电器、军工、航天、环保和桥梁等国民经济领域中起到了举足轻重的作用。
四氟乙烯板适用于-180℃~ 250℃温度下,主要用作电器绝缘材料及接触腐蚀介质的衬里、支承滑块、道轨密封件及润滑材料,富柜家具把它用于轻工业中,广泛应用于化工、医药、染料业容器、贮槽、反应塔釜、大型管道的防腐衬里材料;航空、军事等重工业领域;机械、建筑、交通桥梁滑块、导轨;印染、轻工、纺织业的防粘材料等.ta:image/svg+xml;charset=utf-8,%3Csvg class='icon' viewBox='0 0 1024 1024' xmlns='http://www.w3.org/2000/svg' width='200' height='200'%3E%3Cdefs%3E%3Cstyle%3E@font-face{font-family:feedback-iconfont;src:url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.eot?%23iefix) format(%26apos;embedded-opentype%26apos;),url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.woff2) format(%26apos;woff2%26apos;),url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.woff) format(%26apos;woff%26apos;),url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.ttf) format(%26apos;truetype%26apos;),url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.svg%23iconfont) format(%26apos;svg%26apos;)}%3C/style%3E%3C/defs%3E%3Cpath d='M862.057 708.024H774.74a22.958 22.958 0 0 0-22.565 23.35V910.72a23.743 23.743 0 0 0 6.671 16.483 21.78 21.78 0 0 0 15.894 6.671h87.318a21.584 21.584 0 0 0 15.698-6.671 23.743 23.743 0 0 0 6.672-16.483V731.57a24.724 24.724 0 0 0-6.476-16.678 22.565 22.565 0 0 0-15.894-6.868z' fill='%23ddd'/%3E%3Cpath d='M861.861 517.886h-699.92a22.958 22.958 0 0 0-22.76 23.547v89.476a22.958 22.958 0 0 0 22.76 22.958h268.43a14.913 14.913 0 0 1 14.717 14.913v242.136a22.958 22.958 0 0 0 6.672 16.287 22.173 22.173 0 0 0 15.894 6.671h88.3a22.173 22.173 0 0 0 15.893-6.671 22.958 22.958 0 0 0 6.671-16.287V668.387a15.698 15.698 0 0 1 4.317-10.792 14.717 14.717 0 0 1 10.4-4.317h268.626a22.958 22.958 0 0 0 22.958-23.154v-88.691a22.958 22.958 0 0 0-22.958-23.547z' fill='%23ddd'/%3E%3Cpath d='M261.033 708.024h-87.318a22.958 22.958 0 0 0-22.565 23.35V910.72a23.743 23.743 0 0 0 6.671 16.483 21.78 21.78 0 0 0 15.894 6.671h87.318a22.37 22.37 0 0 0 15.894-6.671 24.724 24.724 0 0 0 6.476-16.68V731.375a22.958 22.958 0 0 0-22.37-23.35zm213.292-427.761h87.122q22.566 0 22.566 22.565v145.007q0 22.566-22.566 22.566h-87.122q-22.565 0-22.565-22.566V302.828q0-22.565 22.565-22.565zM161.746 90.125H861.86q22.566 0 22.566 22.565v85.553q0 22.565-22.566 22.565H161.746q-22.566 0-22.566-22.565V112.69q0-22.565 22.566-22.565zm612.993 190.138h87.122q22.566 0 22.566 22.565v145.007q0 22.566-22.566 22.566H774.74q-22.565 0-22.565-22.566V302.828q0-22.565 22.565-22.565zm-601.024 0h87.122q22.566 0 22.566 22.565v145.007q0 22.566-22.566 22.566h-87.122q-22.565 0-22.565-22.566V302.828q0-22.565 22.565-22.565z' fill='%23ddd'/%3E%3C/svg%3E");
