Polypropylene (PP) has great chemical resistance properties and is generally described as a commodity resin with engineering resin capabilities. PP raw material comes in standard grade. FDA grades are available. The natural color of the raw material is white; colorant can be added to the raw material to meet the customer’s needs.  This material, in its natural state, is lighter than water, meaning PP balls float in water. The ball blanks can be manufactured by injection molding or CNC lathe operation.
