現在(zai)的(de)(de)(de)無邊模具(ju)生(sheng)產的(de)(de)(de)制(zhi)(zhi)品(pin)(pin)，膠邊特別(bie)薄， 有時起(qi)模時就被帶掉或輕輕一擦就可(ke)以(yi)去(qu)掉。但這(zhe)種(zhong)模具(ju)成(cheng)本較高，易(yi)損壞，大多數橡(xiang)膠模制(zhi)(zhi)品(pin)(pin)在(zai)硫化(hua)之后都需(xu)要修整(zheng)處(chu)理。橡(xiang)膠制(zhi)(zhi)品(pin)(pin)生(sheng)產工(gong)藝流程(cheng)更具(ju)體(ti)一點說：橡(xiang)膠加工(gong)的(de)(de)(de)過程(cheng)主要是解決可(ke)塑性(xing)和彈性(xing)之間的(de)(de)(de)矛盾。通過各種(zhong)加工(gong)方法，彈性(xing)橡(xiang)膠成(cheng)為可(ke)塑性(xing)的(de)(de)(de)塑料。加入各種(zhong)添加劑制(zhi)(zhi)成(cheng)半(ban)(ban)成(cheng)品(pin)(pin)后，通過硫化(hua)，塑料半(ban)(ban)成(cheng)品(pin)(pin)成(cheng)為工(gong)具(ju)橡(xiang)膠制(zhi)(zhi)品(pin)(pin)具(ju)有高彈性(xing)和良好的(de)(de)(de)物理機械性(xing)能。

由與丁二(er)烯共聚合(he)而成，橡(xiang)膠(jiao)(jiao)(jiao)螺絲，含量由 18%~50% ，含量越高，對石化油(you)(you)(you)品碳氫燃料油(you)(you)(you)之(zhi)抵(di)抗(kang)性(xing)愈好(hao)，但低溫性(xing)能則變差(cha)，一(yi)般使用溫度范圍為 -25~100 ℃。丁晴膠(jiao)(jiao)(jiao)為目前(qian)油(you)(you)(you)封及 O 型(xing)圈(quan)之(zhi)橡(xiang)膠(jiao)(jiao)(jiao)之(zhi)一(yi) 優(you)點：具(ju)良好(hao)的(de)抗(kang)油(you)(you)(you)，抗(kang)水，橡(xiang)膠(jiao)(jiao)(jiao)螺絲公司，抗(kang)溶劑(ji)(ji)及抗(kang)高壓(ya)油(you)(you)(you)的(de)特(te)(te)性(xing)。缺點：不適(shi)合(he)用于極性(xing)溶劑(ji)(ji)之(zhi)中，例如酮(tong)類、臭(chou)氧、硝(xiao)基烴，MEK 和.用于制(zhi)作燃油(you)(you)(you)箱、潤滑(hua)油(you)(you)(you)箱以及在石油(you)(you)(you)系液壓(ya)油(you)(you)(you)硅油(you)(you)(you)、二(er)酯(zhi)系潤滑(hua)油(you)(you)(you)等流體介質中使用的(de)橡(xiang)膠(jiao)(jiao)(jiao)零件(jian)(jian)，特(te)(te)別是密封零件(jian)(jian).可說是目前(qian)用途廣、成本的(de)橡(xiang)膠(jiao)(jiao)(jiao)密封件(jian)(jian)
