EPDM用于制作發(fā)動(dòng)機(jī)冷卻系統(tǒng)中的密封圈。此類產(chǎn)品接觸的介質(zhì)是防凍液、陽(yáng)光、水、臭氧，使用溫度在-40℃～125℃，短期耐熱溫度可達(dá)135℃。此類零件采用的EPDM，硬度（邵氏A）為60～80（制冷系統(tǒng)中應(yīng)用的圓密封圈為75）；其拉伸強(qiáng)度應(yīng)在10.5MPa以上；斷裂伸長(zhǎng)率一般在175%以上；在伸長(zhǎng)率50%下的定伸應(yīng)力為1～2MPa；在伸長(zhǎng)率**下的定伸應(yīng)力為2～5MPa以上；壓縮變形（150℃，22h）應(yīng)小于20%；其玻璃化轉(zhuǎn)變溫度（TR）比較大為-50℃；耐臭氧老化（50pphm,拉伸20%，72h）應(yīng)無(wú)裂紋；對(duì)于發(fā)動(dòng)機(jī)冷卻系統(tǒng)中應(yīng)用的密封件應(yīng)進(jìn)行冷卻液試驗(yàn)（將試樣放于防凍液中，150℃，166h，試驗(yàn)壓力約0.4MPa），其硬度變化應(yīng)為±5，拉伸強(qiáng)度變化應(yīng)為±20%，斷裂伸長(zhǎng)率變化應(yīng)為-15%～20%，體積改變應(yīng)在±5%；對(duì)于空調(diào)系統(tǒng)中應(yīng)用的密封件，應(yīng)進(jìn)行制冷劑試驗(yàn)（將試樣放于PAG、ND8制冷劑中，100℃，70h）其硬度變化**多為±5，拉伸強(qiáng)度變化**多為±20%，斷裂伸長(zhǎng)率變化**多為-15%～20%，體積改變應(yīng)在±5%之內(nèi)；熱老化試驗(yàn)（150℃，70h），其硬度變化應(yīng)為±5，拉伸強(qiáng)度下降應(yīng)小于10%，伸長(zhǎng)率的下降不能超過(guò)10%。 </p><p> EPDM電纜上的應(yīng)用 </p> <p> 電線電纜上主要用于民用和商用建筑的輸入線、建筑用電線、礦用電纜、核電站用電線、風(fēng)能用線、汽車點(diǎn)火線、控制及信號(hào)電纜。ＩＥＣ標(biāo)準(zhǔn)規(guī)定，分體空調(diào)機(jī)連接電纜不得再使用塑料絕緣電纜，一方面是為了增加柔軟性，同時(shí)耐老化性和安全可靠性。近幾年來(lái)，國(guó)內(nèi)對(duì)橡皮絕緣電線電纜的需求又異乎尋常地多起來(lái)，主要是低壓產(chǎn)品，而１ＫＶ以上的橡皮絕緣電纜，除了船用電纜和礦用電纜以外，電力電纜方面則還是極少?，F(xiàn)代國(guó)外中高壓橡皮絕緣電纜主要是采用乙丙橡膠絕緣，意大利的乙丙膠絕緣電纜早已做到１５０ｋＶ，１５ｋＶ乙丙膠絕緣電纜已經(jīng)是美國(guó)**主流品種。而我國(guó)在這個(gè)產(chǎn)品上還是相當(dāng)落后，船舶及機(jī)械產(chǎn)品出口量的增加，要求船用電纜及潤(rùn)滑油等的標(biāo)準(zhǔn)必須與國(guó)際接軌而增加了乙丙橡膠用量。三元乙丙是乙烯、丙烯和非共軛二烯烴的三元共聚物。</p><div

8.輪胎用EPDM選擇胎側(cè)：輪胎胎側(cè)是輪胎側(cè)向變形比較大的部位,又與大氣直接接觸,要求膠料的耐屈撓性能、耐臭氧性能和耐天候老化性能良好。在胎側(cè)膠配方中添加少量防護(hù)蠟可對(duì)輪胎胎側(cè)起靜態(tài)防護(hù)作用,但在動(dòng)態(tài)條件下防護(hù)作用**減弱,輪胎在使用一段時(shí)間后胎側(cè)仍會(huì)出現(xiàn)大量龜裂。EPDM具有突出的耐臭氧性能、耐天候性能和耐熱性能，并用少量的EPDM可以***提高胎側(cè)的耐臭氧、耐候性能和耐裂口增長(zhǎng)性能。推薦牌號(hào)：錦湖KEP5560推薦理由：窄分子量分布，超高的ENB含量，硫化速度快，用于輪胎制品時(shí)能夠很好的與NR、SBR等二烯類橡膠共混，保證良好的物理性能內(nèi)胎：因具有良好的氣密性能和耐熱性能而在輪胎內(nèi)胎中得到廣泛應(yīng)用"但其加工性能較差存在膠料收縮大&滯后生熱大和加油后易粘輥等問(wèn)題并且老化時(shí)分子鏈傾向于斷裂導(dǎo)致使用后期膠料發(fā)粘嚴(yán)重時(shí)造成內(nèi)外胎粘在一起。乙丙橡膠有優(yōu)異的耐水蒸氣性能并優(yōu)于其耐熱性。KEP-2371錦湖質(zhì)量保證</p><p

8.EPDM粘貼成型EPDM缺少活性基團(tuán)，內(nèi)聚能低，分子鏈段擴(kuò)散性極小，加上膠料容易噴霜，給粘貼成型工藝，尤其是制造多層結(jié)構(gòu)的制品如輪胎胎側(cè)、輸送帶、屋頂材料、膠輥、襯里等帶來(lái)較大的困難。一般可以采取：1）保持需粘合表面新鮮不被污染或用化學(xué)溶液或溶劑處理需粘合的表面；2）在需粘合的表面涂膠粘劑；3）提高粘合部位的溫度、壓力和平整度；4）與其它含活性基團(tuán)的高聚物并用；5）在膠料中加5~10份增粘劑；6）適當(dāng)提高增塑劑的用量；7）采用中間層膠或涂膠液等辦法來(lái)提高粘合力。其中比較簡(jiǎn)單有效地提高粘合力的辦法是提高溫度和壓力。非反應(yīng)性烷基酚醛樹脂增粘效果較好，但同時(shí)也使硫化膠物理機(jī)械性能下降，如彈性下降，長(zhǎng)久變形增大，硫化速度減慢。提高三元乙丙橡膠的粘合力除加增粘劑外，還可在膠料中加由膠粘劑RE、膠黏劑A和白炭黑或膠黏劑RH、膠黏劑A和白炭黑組成的粘合體系，其中白炭黑要選用沉淀法活性白炭黑。此法的缺點(diǎn)是價(jià)格較高。
