Calcium stearate
Main Uses :
1、Used as an additive agent in polyolefin resin production. The recommended dosage is 500-2000ppm. The actual dosage depends on the catalytic activity and the product model.
2、Used as a lubricant and non-toxic stabilizing agent in the plastic industry.
3、Used as a mold release agent in the casting industry and a lubricant in the battery industry.
4、Used as a thickening agent for lubricating oils or ointments.
5、Used as an additive agent in waterproof cement.
Packaging :
The powder is packaged in coated paper bags, each of which has a net weight of 20 kilograms.
The granules are packaged in snakeskin bags, each of which has a net weight of 600 kilograms.
Storage and Transportation Precautions :
Store in a cool and dry place, away from acids and alkali.Usage of hooks is strictly forbidden when loading and unloading. During transport, avoid exposure to heat and moisture, and do not package with acid and alkalisubstances.
Quality Standards :
Implement Standards Q/ITCL2
