1.Compared to other solid plastic balls, hollow PP balls are much cheaper
2.They have light weight. density is 0.91-0.92g/cm3.
3.PP balls have excellent chemical resistance to commonly used acids, oils, and water-based liquids, and have a higher temperature resistance than HDPE.
4.The most important, they are food grade (same as the soda lime glass, stainless steel 304 and 316), so they can used for sous vide cooking balls and cosmetic. There are two types of hollow balls: non-polished PP balls and high polished PP balls.
