聚氯乙烯管材（英文簡稱PVC管材）是由聚氯乙烯樹脂添加必要的穩定劑、滑劑、色料等輔料混合后用熱壓法擠壓成型，是較早得到開發應用的塑料管材。
?
聚乙烯（polyethylene ，簡稱PE）是乙烯經聚合制得的一種熱塑性樹脂。
聚乙烯無臭，無毒，手感似蠟，具有優良的耐低溫性能（最低使用溫度可達-100~-70°C），化學穩定性好，能耐大多數酸堿的侵蝕（不耐具有氧化性質的酸）。
?
PP-R管材、管件是以無規共聚聚丙烯為主要原料，按照GB/T18742生產的管道系統。聚丙烯可分為PP-H（均聚聚丙烯）、PP-B（嵌段共聚聚丙烯）、PP-R（無規共聚聚丙烯）三類。
?
冷熱水用耐熱聚乙烯管材，英文簡稱PE-RT。PE-RT樹脂是由乙烯單體和辛烯單體共聚而成的中密度乙烯—辛烯共聚物。
?
冷耐熱聚乙烯（PE-RT Ⅱ型）管道是一種新型的高分子化學建材。
具有優異的耐熱性、耐腐蝕性、耐沖擊性，良好的柔韌性及密封性，施工維修方便，使用壽命長達50年以上，適用于集中供熱的二次管網系統。
?
電力電纜用非開挖改性聚丙烯（MPP）保護管是以改性聚丙烯為主要原材料，采用特殊配方和加工工藝制造的新型塑料管道。
具有高強度、耐穩性能好、穿放電纜容易、施工簡便、節省費用等一系列優點。
?
膠合劑是PVC專用的接著材料，其膠合作用非一般之糊粘作用，而是和銅鐵等金屬焊接一樣的作用（即分子間之接合），因此，膠著效果極好。
因為使用時接合物不須加熱，所以適于無熱源地區或任何氣候下的施工。
