S50SP is a coarse solid spherical carbon steel granular powder with particles of about 300 micron. Granules of S50SP have a narrow particle size distribution. In other words most particles appear to be the same size. S50SP is used to increase weight in some plastic and rubber products.

Applications of S50SP include:

Shotgun shells/Ammunition, weight bags, high precision masses, blasting, resin casting, adding weight to plastic parts. Plastic parts incorporating S50SP will be detectable by metal detectors.
