塑料用润滑剂的种类比较繁多，从褐煤蜡、石蜡、矿物油、动植物油类等天然物质到各种低分子量聚合物如低分子氟树脂、有机硅油、低密度聚乙烯等，使用较为普遍的是一些脂肪族化合物，例如硬脂酸、硬脂酸皂类、酸脂酸酯类。以及酰胺类化合物。美国1981年在塑料加工中耗用的润滑剂达万多吨，共中酰胺类占45%、硬脂酸及其衍生物占35%，再次是蜡类化合物等。有些润滑剂，如油酸酰胺、硬脂酰胺、脂肪酸的金属盐硬（脂酸镉)等本身又是很好的抗粘贴剂。只要加入0.5%就可使薄膜获很良好的爽滑性。当然二氧化硅、陶土这类填充剂也是最长用的抗粘贴剂，用量为0.1-1.0%，它们又常被称为开口剂。

There are many kinds of lubricants used in plastics. From natural substances such as lignite wax, paraffin, mineral oil, and animal and plant oils to low molecular weight polymers such as low molecular fluorine resin, organic silicon oil and low density polyethylene, some aliphatic compounds are commonly used, such as stearic acid, stearic acid soap and acid fatty acid. Esters. And amides. In 1981, more than 10000 tons of lubricants used in plastic processing were used in the United States. The total amount of amides accounted for 45%, stearic acid and its derivatives accounted for 35%, and again the wax compounds. Some lubricants, such as oleamide, stearamide, hard salt of fatty acids, etc., are good anti sticking agents themselves. The addition of 0.5% can make the film get good skid. Of course, silica and clay filler is the longest used anti sticking agent, and the dosage is 0.1-1.0%. They are also known as openings.
