Grinding foam pellet/projectile are made from flexible polyurethane foam with aluminium oxide adhered to the circumference of the pellet.
The main application is the cleaning of tube and pipe where there is a greater build up of contamination, surface rust or mild scale.
Recommended sizes are approximately 5%larger than the Internal Diameter being cleaned, due to the grit increasing the diameter and reducing the foam pellet/ projectile ability to compact.
