四氟板是優(yōu)良的膜結構建筑材料，其透光性優(yōu)，可降低照明及空調費用，耐久性達20年以上，可降低涂裝清掃費用，對大構架屋頂的建筑工期可縮短50%，可降低屋頂材料費的50%及總建筑費用的20%，量輕耐震不燃，設計自由度大等。因此宜作室外球場、競技場、體育館、滑冰場、游泳池、大型展覽會、動植物園、交通站等的屋頂材料。

在邊界潤滑條件下，降低摩擦系數zui途徑是選擇適用的潤滑添加劑，而四氟板是常用的固體添加劑。實驗證明，機油中添加一定數量的固體添加劑可有效節(jié)約發(fā)動機燃料油5%左右。

改性四氟板是管道、管件、波紋管、泵體、閥門、釜、槽、塔和各類標準設備的襯里shou選材料；作為密封材料在機械、石化、交通運輸、紡織和建筑行業(yè)使用十分；改性四氟板還可用做閥門、軸承、活塞環(huán)、導軌等要求耐蝕和底摩擦件；根據四氟板處理后具有選擇透氣性，可用做分離材料，有選擇的透過氣體或液體，尤其是過濾腐蝕性液體；近年來國外開發(fā)的將改性四氟板用作人造器官，如人造血管、心臟瓣膜等。而且許多新的應用技術和領域不斷被開發(fā)出來，四氟板及其改性材料展現了良好的發(fā)展前景。

根據目前國內外研究生產與應用狀況，我國應該大力發(fā)展改性四氟板的材料，使其商品化、系列化、化，尤其重要的是優(yōu)先發(fā)展需求量大流動性好玻璃纖維、碳纖維、石墨、銅粉填充的四氟板按，充分利用我國稀土資源，開發(fā)稀土填充四氟板和納米改性四氟板新品種將是我國今后重點的研究方向。

在四氟板中加入填充劑，從而改善和克服四氟板的缺陷，目前填充四氟板制品是產量大的PTFE樹脂產品，值得注意的是在國外四氟板填充技術都是由PTFE樹脂生產廠家完成，而我國四氟板填充技術都是由加工生產企業(yè)來完成。通過在PTFE樹脂填充無機類、金屬類和有機高聚物類等不同填料來改善四氟板的耐壓性、性和冷卻性，這些填料要求能經受住PTFE的燒結溫度；不與PTFE反應；另外具有一定粒度并能改善PTFE的一些物化性能。

無機填充材料，常用無機材料主要有玻璃纖維、石墨、二硫化鋁和碳纖維等。填充四氟板的玻璃纖維一般為無堿玻纖，填充量為15%～25%，復合后四氟板的度可增加500倍以上，耐蠕變性和抗冷流性都有較大程度提高與改善；二硫化鋁的加入可以有助于提高四氟板的硬度，降低初期的磨損量；石墨可以單獨使用，也可以與玻璃纖維或炭黑配合使用，石墨填充的四氟板具有優(yōu)良的耐化學藥品性、壓縮蠕變性和較好的導熱性；少量碳纖維填充四氟板即可達到碳和石墨填充效果，而且具有極強的抗拉性能，但是碳纖維價格昂貴，應用受到一定限制。

金屬填充材料，為了改善四氟板的機械性能、導熱性能和尺寸穩(wěn)定性，通常采用鐵、銅、鉛、鋁、鎢、銀等金屬及其氧化物來填充四氟板，目前關于金屬填充技術研究比較多，尤其是銅及其合金為常用，銅粉填充四氟板可以提高制品的抗蠕變性、抗壓強度、硬度及尺寸穩(wěn)定性等。

有機填充材料，用于填充四氟板的有機材料主要是有機纖維和高分子聚合物，有機填充可使四氟板的耐熱性、抗蠕變性、抗壓能力、壓縮、彎曲和性能得到改善。為了提高填充劑與四氟板的界面粘接性，防止燒結時分解，一般需要對填充劑進行適當處理，獲得的相容性和表面效應。
