MDPE是什么材料?
中密度聚乙烯(MDPE)樹脂是用低壓法由乙烯和α-烯烴共聚生產制得,
其密度在0.9260.94g/cm3范圍內。
(1)性能與特征中密度聚乙烯的性能大多數介于高密度聚乙烯和
低密度聚乙烯性能之間,其制品有較好的柔性和低溫特性;拉
伸強度、硬度、耐熱性等特性比高密度聚乙烯略差些,
但其耐環境應力開裂性和強度的穩定性要好于高密度聚乙烯。
(2)成型方法中密度聚乙烯樹脂成型塑料
制品可用擠出成型、注塑成型、擠出-吹塑成型、粉末成型、滾塑成型和旋轉成型等方法成型管材、薄膜、容器和儲槽等塑料制品。
(3)用途塑料管用于輸送有一定壓力的液體;薄膜用于物品包裝;容器和各種形狀儲槽用于化工、醫藥等工業中。 。以上文獻若需轉載請備注出處:PBT樹脂 //shanglikaiguan.cn/
