Calcium Stearate is mainly used as lubricant, emulsifier, stabilizer, releasing agent, accelerant etc.
Molecular formula: Ca (C17H35COO)2
Molecular weight: 606
CAS No.: 1592-23-0
EC No.: 216-472-8
Applications: Calcium stearate is widely used in food, medicine, cosmetic, plastic, rubber fields, mainly function as lubricant, emulsifier, stabilizer, releasing agent, accelerant etc. It can boost the freezing rate in hard plastic product. Also it is applied in the innoxious soft film,such as food packing and medicine apparatus, can effectively improve film’s stability. It is stabilizer & lubricant in PVC and PE. It is halogen adsorbent in PE and PP, can eliminate the poor effect on resin’s color and stalibility because of catalyst remains. Besides it is widely used to improve plastic’s thermostability, better plastic’s air-conductivity, in future it will replace noxious stabilizer with same functions.
