四氟板是优良的膜结构建筑材料，其透光性优，可降低照明及空调费用，耐久性达20年以上，可降低涂装清扫费用，对大构架屋顶的建筑工期可缩短50%，可降低屋顶材料费的50%及总建筑费用的20%，量轻耐震不燃，设计自由度大等。因此宜作室外球场、竞技场、体育馆、滑冰场、游泳池、大型展览会、动植物园、交通站等的屋顶材料。

在边界润滑条件下，降低摩擦系数zui途径是选择适用的润滑添加剂，而四氟板是常用的固体添加剂。实验证明，机油中添加一定数量的固体添加剂可有效节约发动机燃料油5%左右。

改性四氟板是管道、管件、波纹管、泵体、阀门、釜、槽、塔和各类标准设备的衬里shou选材料；作为密封材料在机械、石化、交通运输、纺织和建筑行业使用十分；改性四氟板还可用做阀门、轴承、活塞环、导轨等要求耐蚀和底摩擦件；根据四氟板处理后具有选择透气性，可用做分离材料，有选择的透过气体或液体，尤其是过滤腐蚀性液体；近年来国外开发的将改性四氟板用作人造器官，如人造血管、心脏瓣膜等。而且许多新的应用技术和领域不断被开发出来，四氟板及其改性材料展现了良好的发展前景。

根据目前国内外研究生产与应用状况，我国应该大力发展改性四氟板的材料，使其商品化、系列化、化，尤其重要的是优先发展需求量大流动性好玻璃纤维、碳纤维、石墨、铜粉填充的四氟板按，充分利用我国稀土资源，开发稀土填充四氟板和纳米改性四氟板新品种将是我国今后重点的研究方向。

在四氟板中加入填充剂，从而改善和克服四氟板的缺陷，目前填充四氟板制品是产量大的PTFE树脂产品，值得注意的是在国外四氟板填充技术都是由PTFE树脂生产厂家完成，而我国四氟板填充技术都是由加工生产企业来完成。通过在PTFE树脂填充无机类、金属类和有机高聚物类等不同填料来改善四氟板的耐压性、性和冷却性，这些填料要求能经受住PTFE的烧结温度；不与PTFE反应；另外具有一定粒度并能改善PTFE的一些物化性能。

无机填充材料，常用无机材料主要有玻璃纤维、石墨、二硫化铝和碳纤维等。填充四氟板的玻璃纤维一般为无碱玻纤，填充量为15%～25%，复合后四氟板的度可增加500倍以上，耐蠕变性和抗冷流性都有较大程度提高与改善；二硫化铝的加入可以有助于提高四氟板的硬度，降低初期的磨损量；石墨可以单独使用，也可以与玻璃纤维或炭黑配合使用，石墨填充的四氟板具有优良的耐化学药品性、压缩蠕变性和较好的导热性；少量碳纤维填充四氟板即可达到碳和石墨填充效果，而且具有极强的抗拉性能，但是碳纤维价格昂贵，应用受到一定限制。

金属填充材料，为了改善四氟板的机械性能、导热性能和尺寸稳定性，通常采用铁、铜、铅、铝、钨、银等金属及其氧化物来填充四氟板，目前关于金属填充技术研究比较多，尤其是铜及其合金为常用，铜粉填充四氟板可以提高制品的抗蠕变性、抗压强度、硬度及尺寸稳定性等。

有机填充材料，用于填充四氟板的有机材料主要是有机纤维和高分子聚合物，有机填充可使四氟板的耐热性、抗蠕变性、抗压能力、压缩、弯曲和性能得到改善。为了提高填充剂与四氟板的界面粘接性，防止烧结时分解，一般需要对填充剂进行适当处理，获得的相容性和表面效应。
