錦湖Polychem是由韓國合成橡膠工業(yè)（株）[現錦湖石油化學（株）]與日本合成橡膠（株）[現JSR（株）]的合作而成立。于1988年成功引進美國埃克森化工（ExxonChemical）的先進技術生產，2015年第四條生產線建成后，產量達22萬噸每年，已成為亞洲***位，世界第三位EPDM制造商。錦湖POLYCHEM位于麗水石油化學國家產業(yè)區(qū)，是韓國首批EPDMMaker，錦湖乙丙膠的生產技術采用的是傳統(tǒng)的齊格勒-納塔（Z-N）催化體系，具有牌號完善，選擇性強，性價比高產品質量穩(wěn)定，產能高等優(yōu)勢。錦湖POLYCHEM生產的EP(D)M是主要用于汽車配件領域的高性能特殊合成橡膠，KEP-7141錦湖質量保證，耐熱性、耐臭氧性、耐化學性均很***。既比其他橡膠重量輕，KEP-7141錦湖質量保證，KEP-7141錦湖質量保證，又可以實現高度填充，經濟性好，不僅可用于車身密封輪胎和密封管以及軟管，還可用于電線和建筑輔材等。三元乙丙橡膠高溫流動性較好，故制造模壓制品時沒有什么困難。KEP-7141錦湖質量保證</p><div

2.過氧化物硫化時要加入防老劑才能使硫化中生成的碳．碳鍵的耐熱老化性能充分發(fā)揮。典型的聚合型喹啉防老齊ＵＴＭＱ（ＲＤ）對過氧化物硫化的干擾**?。Ａ肯陆递^小，壓縮長久變形增大較小），但是更強的自由基捕捉型防老劑４４５（二烷基二苯胺）卻可達到更好的高溫老化后物理性能。防老劑４４５和防老劑增效劑ＭＢＺ搭配使用提供了比較好的空氣老化后綜合性能保持率。ＥＰＤＭ過氧化物交聯(lián)體系中加入含氯聚合物如ＣＲ、ＣＳＭ等可進一步提高ＥＰＤＭ硫化膠的抗老化性能。ＣＲ、防老劑４４５和防老劑增效劑Ｍ舊Ｚ三者并用可使ＥＰＤＭ獲得比較好的耐熱效果。 </p> <p> 乙烯基硅烷偶聯(lián)劑Ａ１７２的加入有助于提高ＥＰＤＭ高溫老化后的伸長率保持率。使用乙烯基硅烷還能使ＥＰＤＭ電纜橡皮膠料在水浸漬期間保持電絕緣性能，乙烯基硅烷偶聯(lián)劑能改善聚合物與填料的結合強度，防止浸入，從而使ＥＰＤＭ保持了很好的電性能。ＥＰＤＭ配合中，如將ＬＥＰＤＭ替代配方中的石蠟油類軟化劑可進一步提高ＥＰＤＭ的高溫耐熱性。錦湖EPDM KEP-370F乙丙橡膠為非結晶橡膠，其抗疲勞性能尤其是抗龜裂增長不是很好。與ＳＢＲ相當。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="KEP-7141錦湖質量保證,錦湖"

8.輪胎用EPDM選擇胎側：輪胎胎側是輪胎側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。在胎側膠配方中添加少量防護蠟可對輪胎胎側起靜態(tài)防護作用,但在動態(tài)條件下防護作用**減弱,輪胎在使用一段時間后胎側仍會出現大量龜裂。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***提高胎側的耐臭氧、耐候性能和耐裂口增長性能。推薦牌號：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胎：因具有良好的氣密性能和耐熱性能而在輪胎內胎中得到廣泛應用"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題并且老化時分子鏈傾向于斷裂導致使用后期膠料發(fā)粘嚴重時造成內外胎粘在一起。 </p><p> 8.EPDM粘貼成型EPDM缺少活性基團，內聚能低，分子鏈段擴散性極小，加上膠料容易噴霜，給粘貼成型工藝，尤其是制造多層結構的制品如輪胎胎側、輸送帶、屋頂材料、膠輥、襯里等帶來較大的困難。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）與其它含活性基團的高聚物并用；5）在膠料中加5~10份增粘劑；6）適當提高增塑劑的用量；7）采用中間層膠或涂膠液等辦法來提高粘合力。其中比較簡單有效地提高粘合力的辦法是提高溫度和壓力。非反應性烷基酚醛樹脂增粘效果較好，但同時也使硫化膠物理機械性能下降，如彈性下降，長久變形增大，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。此法的缺點是價格較高。三元乙丙橡膠具有較高的增稠能力有著較好的抗剪切穩(wěn)定性及耐低溫和抗氧化性能。</p><div

短纖維／橡膠復合材料（ＳＦＲＣ）將纖維的剛性與橡膠的柔性有機結合在一起，滿足一些橡膠制品的某些性能特殊要求，在傳動帶、膠管、密封制品等廣泛應用。ＳＦＲＣ性能強烈依賴于纖維的形狀系數（長徑比）、短纖維在橡膠基體的分散及取向、纖維與橡膠的黏合等。由于ＥＰＤＭ分子結構中缺少活性基團，內聚能低，與纖維之間界面作用弱，影響纖維的分散和黏合，因此纖維的表面處理對ＥＰＤＭ的ＳＦＲＣ非常重要。經過改性處理的短纖維對ＥＰＤＭ膠料的交聯(lián)反應具有某種催化作用，它能增加交聯(lián)速度和交聯(lián)密度，使復合材料獲得更大的強度和彈性。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。KEP-7141錦湖質量保證</p><p
