Applications

Suitable for use as an abrasive blasting material in place of garnet or copper slag.

Used as a counter balance in mixing materials

Used as filtration media during recycling of industrial waste water

Because PS Ball has nonslip properties, it can be applied as layer of a road pavement system.

Due to its coherence with asphalt or concrete, PS Balls can be used as efficient Repair or Reinforcement Material.

PS Balls can be used as filter and drainage material in waste landfill system, due to its hardness and spherical shape.

Also used in the field of ship industries and oil refinery plant maintenance for short blasting purposes.
