庫門密封條，糧庫門密封條，阻燃門窗密封條，玻璃密封條，錦湖耐老化EPDM，自動旋轉(zhuǎn)門密封條，建筑門密封條，幕墻密封條等。門窗密封條特點：塑鋼門窗密封條是近年來應(yīng)用較廣的新一代門窗，它較普通門窗密封條有更好的防腐性、耐候性、降噪隔熱效果。塑鋼門窗密封條表面光潔，不但具有優(yōu)異的密封防水性能，還起著美觀裝飾的作用。在選材方面，一般要求較高的廠家都選用三元乙丙橡膠或熱塑性三元乙丙橡膠。 </p> <p> 機(jī)柜密封條：電氣柜密封條是由具有良好彈性和抗壓縮變形、耐老化，錦湖耐老化EPDM、臭氧、化學(xué)作用、較寬的使用溫度范圍（ -40℃~1 20℃）的三元乙丙橡膠 (EPDM) 橡膠發(fā)泡與密實復(fù)合而成，內(nèi)含獨特的金屬夾具和舌形扣，堅固耐用 .

ＥＰＤＭ／聚酰胺（ＰＡ）：ＰＡ具有很高的抗張強(qiáng)度和抗沖擊韌性和耐磨性，與ＥＰＤＭ共混為一種高彈性模量和良好加工性能的彈性體，主要用于制造汽車零部件和建筑材料。北京化工大學(xué)馬勇等選用氯化聚乙烯（ＣＰＥ）作為ＥＰＤ脅體系的增容劑，研究得至ＵＣＰＥ的比較好用量是ＰＡ的１／２，當(dāng)ＰＡ用量為３０-４０份時產(chǎn)生比較好增***果。該項研究產(chǎn)物**提高了ＥＰＤＭ撕裂強(qiáng)度，而磨耗降低和耐油性提高，尤其是通過壓延拉伸ＰＡ能形成類似短纖維補(bǔ)強(qiáng)的微纖復(fù)合材料（ⅧＲＣ）。 </p> <p> ＥＰＤＭ／有機(jī)硅硅橡膠（ｖＭＱ）ＥＰＤＭ與有機(jī)硅橡膠改性，可以獲得許多優(yōu)異特性，在耐熱性、耐候性、壓縮長久變形性能方面優(yōu)于硅橡膠，既可用硫磺硫化，又可用過氧化物硫化，適用于多種成型方式，因此可用于硅橡膠或乙丙橡膠不能適應(yīng)的場合，如汽車減震材料、發(fā)動機(jī)耐熱部件、電氣部件等，耐熱等級從ＥＰＤＭ的１５０℃提高到１７５℃。

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)，乙丙橡膠的長期工作溫度可達(dá)１２０℃，比較高連續(xù)工作溫度為１５０℃，短時間甚至可耐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，乙丙橡膠便開始緩饅分解。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。加入適當(dāng)防老劑，會進(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，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。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。錦湖耐老化EPDM</p><p

三元乙丙橡膠是乙烯、丙烯和少量的非共軛二烯烴的共聚物，是乙丙橡膠的一種，以EPDM（EthylenepyleneDieneMonomer）表示，因其主鏈?zhǔn)怯苫瘜W(xué)穩(wěn)定的飽和烴組成，只在側(cè)鏈中含有不飽和雙鍵，故其耐臭氧、耐熱、耐候等耐老化性能優(yōu)異，可***用于汽車部件、建筑用防水材料、電線電纜護(hù)套、耐熱膠管、膠帶、汽車密封件等領(lǐng)域。三元乙丙橡膠是乙烯、丙烯以及非共軛二烯烴的三元共聚物，1963年開始商業(yè)化生產(chǎn)。每年全世界的消費量是80萬噸。EPDM**主要的特性就是其優(yōu)越的耐氧化、抗臭氧和抗侵蝕的能力。由于三元乙丙橡膠屬于聚烯(PA66)烴家族，它具有極好的硫化特性。在所有橡膠當(dāng)中，EPDM具有比較低的比重。它能吸收大量的填料和油而影響特性不大。因此可以制作成本低廉的橡膠化合物。錦湖耐老化EPDM</p><p
