ＥＰＤＭ的硫化速度較慢，耐油性及粘合性較差，若使其與橡膠如天然橡膠（ＮＲ）、丁腈橡膠（ＮＢＲ），加工性能優(yōu)異三元乙丙膠錦湖歡迎來電、丁基橡膠（ＩＩＲ）、甲基乙烯基硅橡膠（ＶＭＱ）、氯磺化聚乙烯（ＣＳＭ）、氯丁橡膠（ｃＲ）、氯化聚乙烯（ＣＰＥ）等并用改性，可以很好地綜合不同種類橡膠的優(yōu)異性能，改善各自的不足。一方面，ＥＰＤＭ可以改善其他膠種的耐熱性、耐低溫性、耐臭氧及耐水蒸氣性能等；另一方面，又會(huì)使ＥＰＤＭ本身的加工性、耐油性和粘合性得到提高，加工性能優(yōu)異三元乙丙膠錦湖歡迎來電。因此，ＥＰＤＭ與其他橡膠共混改性，可制造出許多具有優(yōu)異性能的新材料。ＥＰＤＭ具有飽和主鏈和低不飽和側(cè)鏈，與塑料和其他橡膠共混、動(dòng)態(tài)硫化改性，可制造多種性能優(yōu)異的新型材料，加工性能優(yōu)異三元乙丙膠錦湖歡迎來電。典型共混物是與聚丙烯（ＰＰ）共混動(dòng)態(tài)硫化改性制成全硫化ＴＰＶ。三元乙丙橡膠(EPDM)常用依據(jù)不同的性能要求可使用硫黃、過氧化物及樹脂硫化。加工性能優(yōu)異三元乙丙膠錦湖歡迎來電</p><div

乙丙橡膠的耐熱及耐熱氧老化性能優(yōu)于其他通用橡膠，只要配合適當(dāng)，乙丙橡膠的長(zhǎng)期工作溫度可達(dá)１２０℃，比較高連續(xù)工作溫度為１５０℃，短時(shí)間甚至可耐２３０～２６０℃高溫。這種良好的耐熱老化性能使其成為制造耐熱輸送帶、耐熱膠管等耐熱制品較為理想的彈性體材料。不過，當(dāng)使用溫度高于１５０℃時(shí)，乙丙橡膠便開始緩饅分解。普通牌號(hào)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。加入適當(dāng)防老劑，會(huì)進(jìn)一步改善乙丙橡膠的耐高溫性能。為了獲得硫黃硫化時(shí)比較好的耐熱性能，另外加入一些***防老劑可進(jìn)一步改善膠料的耐熱性能。硫黃硫化ＥＰＤＭ膠料中使用***自由基捕捉型防老劑如防老劑ＡＭ和其與防老劑增效劑如防老劑ＭＢ搭配使用時(shí)，兩種添加防護(hù)體系膠料的耐熱性能均比不加防老劑的時(shí)好。而且兩種防老劑搭配使用比單用自由基捕捉型防老劑好。錦湖三元乙丙膠

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(cè)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(gè)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(qiáng)度，在高溫情況下更高的生坯強(qiáng)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(huì)使得橡膠的流動(dòng)性能變差，這意味橡膠后續(xù)加工會(huì)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(jìn)硫化速度，硫化狀態(tài)以及注塑行為。 </p><p> 硫化類型三元乙丙可以利用有機(jī)過氧化物或者硫來進(jìn)行硫化。但是，相比與硫磺硫化，過氧化物交鏈的三元乙丙用于電線電纜工業(yè)時(shí)具有更高的溫度抗性，更低的壓縮形變以及改進(jìn)的硫化特性。過氧化物硫化的不好的地方就在于更高的成本。正如前面所提到的，三元乙丙的交鏈速度和硫化時(shí)間隨著硫化類型和含量而改變。當(dāng)三元乙丙與丁基，天然橡膠，丁苯橡膠混合時(shí)，在選擇合適的三元乙丙產(chǎn)品時(shí)，必須要考慮到下列因素：當(dāng)與丁基進(jìn)行混合時(shí)，由于丁基具有較低的不飽和度，為適應(yīng)丁基的硫化速度，比較好選擇相對(duì)較低含量的DCPD和ENB含量的三元乙丙。當(dāng)與天然橡膠和丁苯橡膠混合時(shí)，比較好選擇8%到10%ENB含量的三元乙丙，以滿足其硫化速度。三元乙丙橡膠是由乙烯、丙烯經(jīng)溶液共聚合而成的橡膠，再引入第三單體（ENB）。三元乙丙橡膠基本上是一種飽和的高聚物，耐老化性能非常好、耐天候性好、電絕緣性能優(yōu)良、耐化學(xué)腐蝕性好、沖擊彈性較好。乙丙橡膠的**主要缺點(diǎn)是硫化速度慢；與其它不飽和橡膠并用難，自粘和互粘性都很差，故加工性能不好。三元乙丙橡膠耐過熱水性能亦較好，但與所用硫化系統(tǒng)密切相關(guān)。</p><div

8.EPDM防水卷材三元乙丙橡膠(EPDM)卷材是目前世界公認(rèn)的性能比較好異的防水材料，近年來,橡膠防水卷材在我國(guó)迅速發(fā)展,已成為一種多品種、多規(guī)格、多檔次及多功能的橡膠制品,防水卷材的應(yīng)用領(lǐng)域很廣，如平屋面和低坡度住宅建筑的屋面工程和地下工程，住宅小區(qū)的停車場(chǎng)的頂板，層間和地下，公用設(shè)施以及游泳池等工程的防水，明挖法地鐵隧道工程中地下結(jié)構(gòu)的主體結(jié)構(gòu)全外包防水和頂板防水，車問及出入口通道，蓋挖法施工的車站頂板防水等。防水卷材作為防水層材料的優(yōu)點(diǎn)和工程應(yīng)用的優(yōu)勢(shì)是無可爭(zhēng)辯的。三元乙丙橡膠防水材料分子的耐用年限據(jù)測(cè)算可達(dá)５４年。三元乙丙橡膠防水卷材彈性好、拉伸性能優(yōu)異、抵抗應(yīng)力變形和基層開裂的能力強(qiáng)，具有高斷裂強(qiáng)度、撕裂強(qiáng)度和抗刺穿強(qiáng)度；通過熱焊接能形成強(qiáng)于卷材的接縫；具有高的反射率；卷材不含氯。三元乙丙中*****使用的是ENB，它比DCPD產(chǎn)品硫化要快得多。錦湖膠黏劑用三元乙丙膠</p><p
