聚氯乙烯管材（英文简称PVC管材）是由聚氯乙烯树脂添加必要的稳定剂、滑剂、色料等辅料混合后用热压法挤压成型，是较早得到开发应用的塑料管材。
聚乙烯（polyethylene ，简称PE）是乙烯经聚合制得的一种热塑性树脂。
聚乙烯无臭，无毒，手感似蜡，具有优良的耐低温性能（最低使用温度可达-100~-70°C），化学稳定性好，能耐大多数酸碱的侵蚀（不耐具有氧化性质的酸）。
PP-R管材、管件是以无规共聚聚丙烯为主要原料，按照GB/T18742生产的管道系统。聚丙烯可分为PP-H（均聚聚丙烯）、PP-B（嵌段共聚聚丙烯）、PP-R（无规共聚聚丙烯）三类。
冷热水用耐热聚乙烯管材，英文简称PE-RT。PE-RT树脂是由乙烯单体和辛烯单体共聚而成的中密度乙烯—辛烯共聚物。
冷耐热聚乙烯（PE-RT Ⅱ型）管道是一种新型的高分子化学建材。
具有优异的耐热性、耐腐蚀性、耐冲击性，良好的柔韧性及密封性，施工维修方便，使用寿命长达50年以上，适用于集中供热的二次管网系统。
电力电缆用非开挖改性聚丙烯（MPP）保护管是以改性聚丙烯为主要原材料，采用特殊配方和加工工艺制造的新型塑料管道。
具有高强度、耐稳性能好、穿放电缆容易、施工简便、节省费用等一系列优点。
胶合剂是PVC专用的接著材料，其胶合作用非一般之糊粘作用，而是和铜铁等金属焊接一样的作用（即分子间之接合），因此，胶著效果极好。
因为使用时接合物不须加热，所以适于无热源地区或任何气候下的施工。
