产品用途：该产品有较好的润滑性，可作为化妆品、陶瓷工艺品、聚乙烯、聚苯乙烯、ABS、酚醛树脂等热塑性及热固性树脂的润滑剂和脱模剂。同时它还可以作为聚氯乙烯的热稳定剂，初期着色性好，无硫化污染，滑润性好，有一定的热稳定性。但用量应适当，用量过多反而会对PVC有催化降解作用，一般与钙皂、铝皂及其他热稳定剂配合使用，或与螯合剂（如亚磷酸脂）等配合使用。包装及贮存：纺织袋加内衬衫 包装，每袋20kg±0.5kg.

Product use: this product has good lubricity, can be used as a cosmetic, ceramic crafts, polyethylene, polystyrene, ABS, phenolic resin and other thermoplastic and thermosetting resin of lubricant and release agent. At the same time, it also can be used as PVC thermal stabilizer, early good coloring, no sulfide pollution, good lubrication, there is a certain thermal stability. But the dosage should be appropriate, use too much may have a catalytic degradation effect on PVC, generally with calcium soap, aluminum soap and other heat stabilizer, or with chelating agent (such as phosphite ester). Packing and storage: woven shirt inside the packing, 20 kg - 0.5 kg per bag.
