塑化劑(Plasticizers),或稱增塑劑、可塑劑,是一種增加材料的柔軟性或是材料液化的添加劑。其添加對象包含了塑膠、混凝土、牆版泥灰、水泥與石膏等等。同一種塑化劑常常使用在不同的對象上,但其效果往往並不相同。塑化劑種類多達百餘種,但使用得最普遍的即是一群稱為鄰苯二甲酸酯類的化合物。據統計2004年全世界的塑化劑市場,總量約在550萬噸左右並朝600萬噸邁進。
塑膠添加塑化劑依據使用的功能、環境不同,製造成擁有各種韌性的軟硬度、光澤的成品,其中愈軟的塑膠成品所需添加的塑化劑愈多。一般常使用的保鮮膜,一種是無添加劑的PE(聚乙烯)材料,但其黏性較差;另一種廣被使用的是PVC(聚氯乙烯)保鮮膜,有大量的塑化劑,以讓PVC材質變得柔軟且增加黏度,非常適合生鮮食品的包裝。
混凝土使用塑化劑(減水劑),可以增加混合物的工作性方便施工不易產生蜂窩,從而可減少含水比例,增加強度。牆版泥灰使用塑化劑可以增加混合物的液化程度,如此便不用添加太多水分,可減少乾燥牆版所需的工夫。
