NGE Hollow Plastic Balls, Color : White /Black / RED / Customize

PP(Polypropylene)Balls have all the great mechanical properties of acetal resin, These balls are precision ground for tight tolerance & are made of solid, high-quality thermoplastic. The tolerance is ±.001" for all sizes and the color is Natural (white)

Very resistant to most acids and alkalies, Polypropylene Balls are useful for vapor and evaporation shields in electrolytic solutions. Because their Specific Gravity is less than water, they are excellent for liquid level float applications.
