[Introduction]:
[Chemical formula]: Ca[CH3(CH2)16COO]2
[Characters]:
Calcium sterate is kind of fine white powder with greasy touch sense,soluble in hot water,methylbenzene,ethanol and other organic solvents,innoxious,slowly decomposes into stearic acid and calcium salts when it is heated to 400°C.
[Applications]:
Calcium stearate is widely applied 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 medicin apparatus,can effectively improve film’s stability. It is stabilizer&lubricant in PVC and PE. It is halogn adsorbent in PE ang 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.
