常見彈性體材料
根據(jù)彈性體是否可塑化可以分為熱固性彈性體,熱塑性彈性體二大類。熱固性彈性體,這也就是傳統(tǒng)意義的橡膠(Rubber),熱塑性彈性體(Thermoplastic elastomer),縮寫為
TPE,為上世紀(jì)90年代開始逐漸被越來越多的商業(yè)化應(yīng)用。這個分類同樣也說明了這二類彈性體加工所采用的是兩種不同的方式:橡膠用熱固性設(shè)備加工,
TPE采用熱塑性設(shè)備加工。
彈性體按照原料組成分類如下:
1、傳統(tǒng)橡膠(Rubber)
(1)不飽和橡膠
天然橡膠 Natural rubber (NR)
異戊橡膠 Synthetic polyisoprene (IR)

丁腈橡膠Nitrile rubber (copolymer of polybutadiene and acrylonitrile, NBR)
氯丁橡膠Chloroprene rubber (CR)
(2)飽和橡膠
丁基橡膠 Isobutylene Isoprene Rubber (IIR) 或 Butyl Rubber
