Zinc stearate applications

Zinc stearate is a necessary ingredient in the compounding of plastic. That also helps to smooth out the plastic and make it easier to work with. One type of powder that is mixed into the plastic compound is calcium zinc stabilizer for pvc. It effectively reduces the friction among particles of plastic, enabling them to more easily glide around each other (and allows them to co-mingle without clumping or crinkling). This is to ensure the plastic is well mixed and will ultimately cure correctly. 

Achieving a Smooth and Matte Finish

Another key feature of zinc stearate is that it gives cosmetics a smooth, dull finish. In products in which zinc stearate is present, it’s one of the factors that make the product feel nice and smooth and give the product a slippery feel upon application. ~The zinc stearate helps give the finish on a product a little bit of matte so that it isn't shiny or reflective of light. This can be essential for products like plastic toys or packaging, where a glossy finish may not be desired.
