Calcium Stearate

Type: Internal Lubricant

Development / Applications

Calcium stearate is pure and additive-free; its granular particle size typically presents no dispersion problems. It is a slip agent with lubricating properties for polymer processes and is recommended for the production of woven fibers.Due to its hydrophobic properties, this product is recommended as a concrete additive. It can be used in PVC, PE-PP polyolefins, polyester, rubber, cosmetics, adhesives, paints, etc. In PVC, it acts as an internal lubricant, promoting fusion and resulting in an excellent surface finish. In injection molding, it is an excellent release agent.The recommended dosage is 0.05 – 0.5 % as a slip and 0.2 – 1.0 phr as a lubricant for PVC compounds depending on the compound in question.
