KEP-330。EPDM主要用于汽車、建筑與施工、輪胎與管、電線與電纜和潤滑添加劑。該需求將不斷地受到增長的終端用戶產(chǎn)業(yè)、彈性體的需求增加、發(fā)展策略提升及擴張和收購活動增加的推動。估計潤滑添加劑是增長**快的應(yīng)用。EPDM還可被用作潤滑劑中的黏度改進劑(Ⅵ)。汽車產(chǎn)業(yè)是全球EPDM市場中比較大的終端用途產(chǎn)業(yè)細(xì)分市場。全球EPDM在汽車產(chǎn)業(yè)中的消費主要是由于其高耐熱性和耐氣候性及振動吸收性能。由于這些性能，EPDM還用于軟管、引擎蓋下的機械產(chǎn)品，錦湖KUMHO KEP-330、車身密封膠、擋風(fēng)雨條、傳送帶、引擎支架，錦湖KUMHO KEP-330、剎車配件、雨刮器等。在汽車產(chǎn)業(yè)中EPDM市場也受到了新興經(jīng)濟體生活標(biāo)準(zhǔn)提高的推動。據(jù)報道，亞太地區(qū)是比較大的EPDM市場，包括中國、日本、馬來西亞、印度、中國臺灣和韓國。2014年亞太地區(qū)市場大約占全球EPDM市場的40％，且在2020年之前預(yù)計這個地區(qū)仍將主導(dǎo)市場。預(yù)計在2020年之前亞太地區(qū)還將是比較大的區(qū)域市場，以高投資于汽車、塑料改性和建筑行業(yè)等應(yīng)用。并且預(yù)計亞太地區(qū)將是增長**快的EPDM市場。這種高增長歸因于不斷增長的汽車市場和中國國內(nèi)需求增加用過氧化物交聯(lián)的三元乙丙橡膠可在更苛刻的條件下使用。錦湖KUMHO

style="text-indent:25px">接枝改性是改善乙丙橡膠性能缺點的重要途徑之一，也為制備綜合性能更優(yōu)異的改性乙丙橡膠提供了可能。乙丙橡膠的接枝改性就是通過在其分子主鏈上接枝含有特征官能團的極性支鏈單體，提高聚烯烴基體與其它極性成分界面的結(jié)合力，使其它極性材料得以均勻分散，提高材料的物理性能及產(chǎn)品的性能穩(wěn)定性，從而改善乙丙橡膠的自粘性、互粘性以及相容性。接枝改性乙丙橡膠主要用于改善乙丙橡膠與其它材料的結(jié)合強度、相容性、填料界面的結(jié)合、制品韌性、沖擊強度、低溫脆性及耐熱性等。乙丙橡膠接枝改性技術(shù)主要包括溶液接枝法、熔融接枝法等，近年來又發(fā)現(xiàn)了電子束輻射接枝和直接溶脹接枝等新的接枝方法，為乙丙橡膠接枝改性提供了更***的技術(shù)可行性。錦湖KUMHO

此概念的基礎(chǔ)上采取添加所需材料的方法。追求“簡單的就是比較好的"這排除計量失誤發(fā)生的可能性，材料的種類是越少越好。為便于在場進行原材料管理，以由于近來各材料生產(chǎn)商都在不斷地開發(fā)新材料，村料也就在所難免。因此使用橡膠產(chǎn)品要求性能上年然而，在不能準(zhǔn)確把任何時候添加材料，都可能成為泄漏、起霜等負(fù)面因素。把握村料效果的情況下，比較好不要盲目地河地添加材料。 </p> <p> 漫合設(shè)計時適宜的材料種類 </p> <p> 聚合體3種以下 </p> <p> 碳/黑 2種以下 </p> <p> 填充物 2種以下 </p> <p> 軟化劑可塑劑 2種以下 </p> <p> 加工助劑 2種以下 </p> <p> 抗老化劑 2種以下 </p> <p> 促進劑(丁晴橡膠混合) 3種以下 </p> <p> 促進劑(三元乙丙橡膠般混合) 4種以下 </p> <p> b.關(guān)于材料的添加量 </p> <p> “比較低添加量比較好為0.2phr以上”其理由在于，在現(xiàn)場使用大型機械進行混煉操作時，經(jīng)常發(fā)生分散不充分的情況并且如添加量少，將會發(fā)生分散不均勻的現(xiàn)象。 </p> <p> 如果不得已要添加0.1phr以下的量時，需要事先完全與材料混合，使?jié)舛冉档?，此外，氧化鋅的比重為5.6左右時，雖然重量份數(shù)為5Phr.但容量份數(shù)為0.891通常添加量不需要5Phr,比較好是添加3Phr以上，在進行硫化過程中，當(dāng)內(nèi)模被行財，可以考慮混合少量的氧化鋅，但這時比較好添加活性氧化鋅活性氧化鋅)。 </p><p> 2. 分子量對三元乙丙膠性能的影響： </p> <p> 三元乙丙橡膠的分子量及分布可以通過凝膠滲透色譜法使用二氯苯作為溶劑在高溫下（150℃）測量而得。分子量分布通常被稱為是重量平均分子量與數(shù)量平均分子量的比例。根據(jù)普通和高度支化的結(jié)構(gòu)，這個值通常在2到5之間變化。三元乙丙橡膠的門尼粘度可以反映其分子量的大小，三元乙丙橡膠的門尼粘度范圍通常在20到100之間。 </p> <p> 增加三元乙丙橡膠的分子量，正面影響有：更高的拉伸和撕裂強度，在高溫情況下更高的生坯強度，能夠吸收更多的油和填料（低成本）。但是過高的分子量也會使得橡膠的流動性能變差，這意味橡膠后續(xù)加工會更加的困難，比如更難混煉，更難充模，更難擠出等等，隨著分子量分布的增加，正面的影響有：增加的混煉和碾磨加工性。但是，較窄的分子量分布可以改進硫化速度，硫化狀態(tài)以及注塑行為。普通牌號的乙丙橡膠即使不加入耐熱型防老劑，也具有良好的耐高溫性能。</p><div

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、汽車點火線、控制及信號電纜。ＩＥＣ標(biāo)準(zhǔn)規(guī)定，分體空調(diào)機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，同時耐老化性和安全可靠性。近幾年來，國內(nèi)對橡皮絕緣電線電纜的需求又異乎尋常地多起來，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**主流品種。而我國在這個產(chǎn)品上還是相當(dāng)落后，船舶及機械產(chǎn)品出口量的增加，要求船用電纜及潤滑油等的標(biāo)準(zhǔn)必須與國際接軌而增加了乙丙橡膠用量。利用EPDM耐制動液（DOT3、DOT4、DOT5（硅油基））的特性，用于液壓制動軟管內(nèi)膠層和制動泵中密封圈的制作。錦湖天然膠共混EPDM</p><p
