|polyethylene glycol terephthalate;[高分子]聚對苯二甲酸乙二醇酯
聚乙烯對苯二甲酸酯(polyethylene terephthalate,縮寫PET)是一種熱塑性聚合物,由對苯二甲酸(terephthalic acid)與乙二醇(ethylene glycol)通過酯化反應和縮聚反應合成。該材料具有高機械強度、耐化學腐蝕性和透明性,屬于聚酯類高分子化合物。
從化學結構來看,PET的重複單元包含剛性的對苯二甲酸基團與柔性的乙二醇鍊段交替排列,這種結構特性使其同時具備優異的尺寸穩定性和加工流動性。根據國際純粹與應用化學聯合會(IUPAC)的命名規則,其系統命名為聚(氧乙烯氧對苯二甲酰)。
在工業應用中,PET主要用于制造:
美國食品藥品監督管理局(FDA)将其列為食品接觸安全材料(21 CFR 177.1630),其玻璃化轉變溫度約70°C,熔點255-265°C。環境方面,美國國家環境保護局(EPA)數據顯示,PET回收率可達29%,屬于1號可回收塑料,但自然降解需要超過450年。
Polyethylene Terephthalate(PET) 是聚對苯二甲酸乙二醇酯的英文名稱,簡稱PET或PETE,是一種熱塑性聚合物,屬于聚酯類材料。以下是詳細解釋:
