Use

 

作聚氯乙烯等热稳定剂和多种塑料加工的润滑剂，脱模剂等。在硬质制品中，与盐基性铅盐、铅皂配合可提高凝胶化速度，也用于食品包装，医疗器具等要求无毒的软质薄膜与器具。还可作聚乙烯，聚丙烯的卤素吸收剂，以消除残留催化剂对颜色和稳定性的不良影响。在橡胶加工中作增塑剂，能使天然橡胶和合成橡胶软化，而对硫化几乎无影响。亦用作聚烯烃纤维和模塑料的润滑剂，润滑脂的增厚剂，纺织品的防水剂，油漆的平光剂，制造塑料唱片时的增塑剂，还用在铅笔芯生产及医药、香料工业中。

 

Heat stabilizers for PVC and other plastics processing and a variety of lubricants, release agents. Products in the hard, and the basicity of the lead salts, lead with soap can increase the rate of gelation, but also for food packaging, medical equipment and other requirements of non-toxic soft film and equipment. Can be made of polyethylene, polypropylene halogen absorbent, to remove residual catalyst on the adverse effects of color and stability. As plasticizers in rubber processing, can soften the natural rubber and synthetic rubber, and almost no effect on curing. Also used as polyolefin fibers and molding lubricant, grease thickening agent, textile waterproofing agents, paint the plain agent, plasticizer, when manufacturing plastic music, also used in pencil manufacturing and medicine, perfume industry in.
