The components of black sand are carbon black and polymer assistant(dispersing agent, lubricating agent,etc...) It is widely used ni engineering modification. Our black sand is specially suited for PA,PC,ABS,PBT,POM,HIPS,LCP,etc...Compare to masterbatch and carbon black, the benefits of using black sand are: less additive amount, no dust emissions, high temperature resistance, high blackness value, and no damage on the original plastic products. According to customer’s needs, we made three types of black sands depending on pellent sizes which are S type, M type, Ftype. S type’s pellet size is about 0.5-2.0mm, Mtype’s pellet size is about 2.0-5.0mm, and F type’s pellet size is about 2.0-5.0mm. These products have been thoroughly pretreated and may save customer extra process costs in producing desire colors.

 

Usage and additive amount:

 

By using our S type black sand, we suggest that you can add a little amount of white mineral oil or diffusion oil in raw material to moist. After that, before you pump the tablets, mix the black sand up and stir them will. If you use M or F type black sand, you can mix them up directly with thermoplastics or recycling plastics and stir them well before you pump the tablets. The addition amount of the black sand is generally between 1%-2% of your final product.(Final additive amount should be based on customers; requirements.)
