1、抗靜電填充型
抗(kang)靜電劑填充(chong)型(xing)產品(pin)的(de)優點是(shi)制品(pin)著色不受限制，其中(zhong)低分子型(xing)抗(kang)靜電劑對產品(pin)性能(neng)影響不大，其表面電阻率為1010-1013Ω。但低分子抗(kang)靜電劑填充(chong)型(xing)產品(pin)的(de)電性能(neng)會隨著時(shi)間的(de)推移而逐漸(jian)喪失。
國(guo)外目(mu)前的主要(yao)開發動(dong)向(xiang)是(shi)研(yan)制(zhi)生(sheng)產(chan)高(gao)分(fen)子(zi)型(xing)抗靜(jing)(jing)(jing)電(dian)劑，高(gao)分(fen)子(zi)型(xing)抗靜(jing)(jing)(jing)電(dian)劑亦可稱為(wei)永久性抗靜(jing)(jing)(jing)電(dian)劑，它不會(hui)像低分(fen)子(zi)型(xing)抗靜(jing)(jing)(jing)電(dian)劑那樣水洗后(hou)或(huo)長(chang)時(shi)間使(shi)用后(hou)便喪(sang)失其導電(dian)性。高(gao)分(fen)子(zi)型(xing)抗靜(jing)(jing)(jing)電(dian)劑的主要(yao)品種有：聚醚型(xing)、季氨(an)鹽型(xing)、磺酸(suan)型(xing)、酸(suan)的接枝共聚物、離(li)子(zi)型(xing)。主要(yao)生(sheng)產(chan)廠家有日本的三(san)洋化(hua)成、住友精化(hua)、住友科(ke)學工(gong)業、第一(yi)(yi)工(gong)業制(zhi)藥，瑞(rui)士的汽巴(ba)精化(hua)、科(ke)萊(lai)恩，美國(guo)的威科(ke)、大湖等。高(gao)分(fen)子(zi)型(xing)抗靜(jing)(jing)(jing)電(dian)劑的添加量是(shi)低分(fen)子(zi)型(xing)抗靜(jing)(jing)(jing)電(dian)劑的5-15倍，同時(shi)還要(yao)考慮其與樹(shu)脂的相(xiang)容性從而(er)選擇適用的相(xiang)容劑，因受(shou)(shou)到成本的制(zhi)約使(shi)其應用受(shou)(shou)到一(yi)(yi)定(ding)限(xian)制(zhi)。國(guo)內目(mu)前主要(yao)是(shi)低分(fen)子(zi)型(xing)抗靜(jing)(jing)(jing)電(dian)劑，特別是(shi)離(li)子(zi)型(xing)抗靜(jing)(jing)(jing)電(dian)劑，易(yi)淅出(chu)，受(shou)(shou)環境(jing)濕度影響(xiang)較(jiao)大。
2、碳系(xi)填充型
這一系列的(de)(de)(de)填(tian)充物主要是導(dao)電(dian)(dian)炭黑(hei)(hei)、石墨和碳纖維，制(zhi)成品(pin)的(de)(de)(de)體積電(dian)(dian)阻率為(wei)102-109Ω·cm。其(qi)(qi)中炭黑(hei)(hei)填(tian)充是主流，炭黑(hei)(hei)填(tian)充型(xing)導(dao)電(dian)(dian)聚合物之(zhi)所以被廣泛采用，其(qi)(qi)一是因為(wei)導(dao)電(dian)(dian)炭黑(hei)(hei)價格較為(wei)低(di)廉；其(qi)(qi)二是因為(wei)炭黑(hei)(hei)能根據(ju)不同的(de)(de)(de)導(dao)電(dian)(dian)性需求有較大的(de)(de)(de)選(xuan)擇余地(di)，它(ta)的(de)(de)(de)制(zhi)成品(pin)的(de)(de)(de)電(dian)(dian)阻值(zhi)可在102-109Ω之(zhi)間的(de)(de)(de)寬(kuan)廣范(fan)圍內變化；其(qi)(qi)三(san)是導(dao)電(dian)(dian)性持久、穩(wen)(wen)定；因此是理想的(de)(de)(de)抗靜電(dian)(dian)材(cai)料(liao)(liao)。但(dan)是它(ta)的(de)(de)(de)制(zhi)成品(pin)僅限于黑(hei)(hei)色，并對材(cai)料(liao)(liao)性能影響較大，需要配套改(gai)性技(ji)術。為(wei)了改(gai)善(shan)并提高導(dao)電(dian)(dian)塑料(liao)(liao)韌性和保持更(geng)佳(jia)的(de)(de)(de)物性以及優異穩(wen)(wen)定的(de)(de)(de)導(dao)電(dian)(dian)性能。
3、金(jin)屬填充型
這(zhe)類導電(dian)(dian)(dian)(dian)塑(su)(su)(su)料(liao)主要(yao)用(yong)于(yu)電(dian)(dian)(dian)(dian)磁(ci)波屏(ping)蔽(bi)(bi)場合。近(jin)年來(lai)由于(yu)集(ji)(ji)成(cheng)電(dian)(dian)(dian)(dian)路(lu)和大規模集(ji)(ji)成(cheng)電(dian)(dian)(dian)(dian)路(lu)技(ji)術的(de)發展(zhan)，數字化(hua)電(dian)(dian)(dian)(dian)子機(ji)器(qi)已從(cong)工業用(yong)向民用(yong)品發展(zhan)。為了提高處(chu)理能力(li)，使用(yong)的(de)電(dian)(dian)(dian)(dian)子線路(lu)和元件(jian)越來(lai)越集(ji)(ji)成(cheng)微型化(hua)、高速化(hua)，其信(xin)號(hao)水平減(jian)小(xiao)，這(zhe)使從(cong)外部侵入(ru)的(de)電(dian)(dian)(dian)(dian)磁(ci)波與控制信(xin)號(hao)相接近(jin)。此外，電(dian)(dian)(dian)(dian)子設備也向外放(fang)射(she)電(dian)(dian)(dian)(dian)磁(ci)波，因此很容易(yi)造成(cheng)電(dian)(dian)(dian)(dian)子機(ji)器(qi)的(de)誤(wu)動作、圖象和聲(sheng)音(yin)干擾。進入(ru)80年代(dai)，電(dian)(dian)(dian)(dian)子機(ji)器(qi)的(de)殼體大多(duo)采(cai)用(yong)塑(su)(su)(su)料(liao)材料(liao)代(dai)替金屬(shu)。這(zhe)是(shi)由于(yu)塑(su)(su)(su)料(liao)作為殼體具有質輕且強(qiang)度高、耐腐蝕、易(yi)加工、生產(chan)效率高、總(zong)成(cheng)本(ben)低(di)等優點。但是(shi)，塑(su)(su)(su)料(liao)是(shi)絕緣體，對于(yu)電(dian)(dian)(dian)(dian)磁(ci)波來(lai)說，完全可以透過(guo)。因此，賦予(yu)塑(su)(su)(su)料(liao)殼體電(dian)(dian)(dian)(dian)磁(ci)波屏(ping)蔽(bi)(bi)能力(li)就成(cheng)為一個有待研究的(de)十分迫切的(de)課題。
