General Description:
Polyethylene (PE) has great chemical resistance properties and is generally described as a “low density” (LD) or “high density” (HD) polymer. The LDPE material tends to be more flexible than the HDPE polymer. PE raw material comes in standard grade and FDA grades are available. The natural color of the raw material is a semi-translucent white; colorant can be added to the raw material to meet the customer’s needs. These materials, in their natural state, are lighter than water, meaning PE balls float in water. The ball blanks can be manufactured by injection molding or CNC lathe operation.
