Product Details
 聚四氟乙烯棒材是一种适用于加工各种在腐蚀介质中工作的衬垫密封件润滑材料以及在各种频率下使用的电绝缘零件等的未加填充的聚四氟乙烯树脂(可含再生聚四氟乙烯树脂)经模压、糊膏挤出或柱塞挤出工艺成型的棒材。

1特性

使用温度范围十分广泛(摄氏从-200度到+260度)。

基本上对所有化学物质都具抗腐蚀性除了一些氟化物和碱性金属液。

极好的机械性能包括抗老化性特别对于弯曲和摆动方面应用。

杰出的阻燃性 (符合ASTM-D635 和 D470测试步骤, 在空气中被规为阻燃材料。

优良的绝缘特性(无论其频率和温度如何)

吸水率极低,并具有自润滑性和不粘性等一系列独特的性能。

2应用

聚四氟乙烯棒材有推压棒和模压棒两种,在已知塑料中聚四氟乙烯具有最优良的耐化学腐蚀性能与介电性能,能在-180℃-+260℃温度下使用,以及具有最低摩擦系数,主要适用一些长的制品和非标规格的机械零件:密封/垫圈、环材、耐磨板/座电、绝缘零件、抗腐蚀性行业、机械零部件、衬层、石油及天然气、石油化工业、化学行业、仪器设备生产商等。

聚四氟乙烯棒的应用领域

化工方面:能用作防腐材料,可制造各种防腐蚀零部件,如管子、阀门、泵及管件接头等。化工设备方面,可制作反应器、蒸馏塔及防腐设备的衬里和涂层。

机械方面:可用作自润滑轴承、活塞环、油封及密封圈等。自润滑性可减少机件磨损和发热,降低动力消耗。

电子电器方面:主要用于制造各种电线电缆、电池电极、电池隔膜、印刷电路板等。

医用材料:利用其耐热、耐水、无毒的特性,可用作各种医疗器械及人工脏器的材料。前者如消毒过滤器、烧杯、人工心肺装置,后者如人造血管、心脏及食道等。已被广泛地应用作为密封材料和填充材料。
