一、丁晴聚氨酯密封隔絕件的總體使用性能
丁晴(qing)橡塑其主要采用了高(gao)溫制(zhi)冷的(de)效果保濕乳液聚合法(fa)性(xing)產(chan)量，丁晴(qing)橡塑兼(jian)有優(you)質產(chan)品的(de)耐(nai)(nai)石油(you)醚性(xing)，其 耐(nai)(nai)石油(you)醚性(xing)不亞于聚硫橡塑和氟(fu)橡塑，因此兼(jian)有的(de)耐(nai)(nai)磨天然橡塑性(xing)隨和密性(xing)，粘(zhan)結力(li)強。丁晴(qing)橡塑的(de)優(you)點(dian)和缺點(dian)是不會耐(nai)(nai)三(san)氧 及(ji)芬芳族、鹵代烴、及(ji)酯類石油(you)醚，不能做電(dian)絕緣建材。丁晴(qing)橡塑耐(nai)(nai)高(gao)溫制(zhi)冷的(de)效果能力(li)差，電(dian)能力(li)低等，回彈力(li)較(jiao)低。
二、丁晴橡塑密封墊件主要的的應用領域
丁晴(qing)(qing)(qing)聚(ju)(ju)氨(an)酯封(feng)密件重要于生(sheng)產設計(ji)丁晴(qing)(qing)(qing)相關食品，如丁晴(qing)(qing)(qing)管、絕緣膠布(bu)、聚(ju)(ju)氨(an)酯膈膜和門(men)頭(tou)油(you)囊等，常于生(sheng)產設計(ji)各種類(lei)型丁晴(qing)(qing)(qing)模壓聚(ju)(ju)氨(an)酯相關食品，如O形圈、油(you)封(feng)、膜片、門(men)伐、波線管等，也于生(sheng)產設計(ji)膠板和耐腐(fu)工件。
三、丁晴塑膠密封性能件的基本上亮點
(1) 丁晴塑膠事(shi)非(fei)凝結性無塑形混物物，生膠強(qiang)度(du)較低，須進入(ru)補強(qiang)劑才具有安全使(shi)用顏值。晴重量考(kao)試分數(shu)較高的丁晴塑膠這樣有利(li)于加快混煉膠的強(qiang)度(du)和耐(nai)磨涂層(ceng)性，但會(hui)使(shi)剛性下調。
(2) 耐老化是(shi)丁晴(qing)(qing)產(chan)品最嚴重的(de)結構(gou)特征(zheng)，丁晴(qing)(qing)產(chan)品含(han)電(dian)性晴(qing)(qing)基，對非電(dian)性或弱電(dian)性的(de)礦(kuang)石(shi)油、動(dong)花(hua)草油、 介質液體主要燃料和溶(rong)液等檢查是(shi)否的(de)物質有優質的(de)抗忍(ren)耐力。晴(qing)(qing)的(de)質量中考分(fen)數(shu)愈高(gao)，耐老化性愈好。
(3) 耐溫性遠(yuan)遠(yuan)超過NR、SBR和CR，可在120℃的熱氧氣中長(chang)期(qi)動用。
(4) 抗寒性、耐超低溫(wen)性偏差，晴品質成績排名(ming)愈高，抗寒性愈差。
(5) 密(mi)封性盡量(liang)，在通用的硅橡膠中比得上IIR。
(6) 耐熱(re)性氧破(po)裂測(ce)試、日曬破(po)裂測(ce)試功效遠低于NR。
(7) 丁晴(qing)再(zai)生(sheng)膠(jiao)的介(jie)電性(xing)能參數比較，屬光電器件再(zai)生(sheng)膠(jiao)。
