四氟板是優(yōu)良的膜結(jié)構(gòu)建筑材料，其透光性優(yōu)，可降低照明及空調(diào)費(fèi)用，耐久性達(dá)20年以上，可降低涂裝清掃費(fèi)用，對(duì)大構(gòu)架屋頂?shù)慕ㄖて诳煽s短50%，可降低屋頂材料費(fèi)的50%及總建筑費(fèi)用的20%，量輕耐震不燃，設(shè)計(jì)自由度大等。因此宜作室外球場(chǎng)、競(jìng)技場(chǎng)、體育館、滑冰場(chǎng)、游泳池、大型展覽會(huì)、動(dòng)植物園、交通站等的屋頂材料。

在邊界潤(rùn)滑條件下，降低摩擦系數(shù)zui途徑是選擇適用的潤(rùn)滑添加劑，而四氟板是常用的固體添加劑。實(shí)驗(yàn)證明，機(jī)油中添加一定數(shù)量的固體添加劑可有效節(jié)約發(fā)動(dòng)機(jī)燃料油5%左右。

改性四氟板是管道、管件、波紋管、泵體、閥門(mén)、釜、槽、塔和各類(lèi)標(biāo)準(zhǔn)設(shè)備的襯里shou選材料；作為密封材料在機(jī)械、石化、交通運(yùn)輸、紡織和建筑行業(yè)使用十分；改性四氟板還可用做閥門(mén)、軸承、活塞環(huán)、導(dǎo)軌等要求耐蝕和底摩擦件；根據(jù)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(guò)氣體或液體，尤其是過(guò)濾腐蝕性液體；近年來(lái)國(guó)外開(kāi)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(yīng)用技術(shù)和領(lǐng)域不斷被開(kāi)發(fā)出來(lái)，四氟板及其改性材料展現(xiàn)了良好的發(fā)展前景。

根據(jù)目前國(guó)內(nèi)外研究生產(chǎn)與應(yīng)用狀況，我國(guó)應(yīng)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(dòng)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(guó)稀土資源，開(kāi)發(fā)稀土填充四氟板和納米改性四氟板新品種將是我國(guó)今后重點(diǎn)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(chǎn)量大的PTFE樹(shù)脂產(chǎn)品，值得注意的是在國(guó)外四氟板填充技術(shù)都是由PTFE樹(shù)脂生產(chǎn)廠家完成，而我國(guó)四氟板填充技術(shù)都是由加工生產(chǎn)企業(yè)來(lái)完成。通過(guò)在PTFE樹(shù)脂填充無(wú)機(jī)類(lèi)、金屬類(lèi)和有機(jī)高聚物類(lèi)等不同填料來(lái)改善四氟板的耐壓性、性和冷卻性，這些填料要求能經(jīng)受住PTFE的燒結(jié)溫度；不與PTFE反應(yīng)；另外具有一定粒度并能改善PTFE的一些物化性能。

無(wú)機(jī)填充材料，常用無(wú)機(jī)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(wú)堿玻纖，填充量為15%～25%，復(fù)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(dú)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(xué)藥品性、壓縮蠕變性和較好的導(dǎo)熱性；少量碳纖維填充四氟板即可達(dá)到碳和石墨填充效果，而且具有極強(qiáng)的抗拉性能，但是碳纖維價(jià)格昂貴，應(yīng)用受到一定限制。

金屬填充材料，為了改善四氟板的機(jī)械性能、導(dǎo)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(lái)填充四氟板，目前關(guān)于金屬填充技術(shù)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(qiáng)度、硬度及尺寸穩(wěn)定性等。

有機(jī)填充材料，用于填充四氟板的有機(jī)材料主要是有機(jī)纖維和高分子聚合物，有機(jī)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(jié)時(shí)分解，一般需要對(duì)填充劑進(jìn)行適當(dāng)處理，獲得的相容性和表面效應(yīng)。
