Corrosion Resistance

Nylon balls are insolvable into diluted mineral acids and in most organic acids. They are resisting to alkalis, petroleum products, greases, inorganic salt solutions, low gradation alcohols, motor oil, transmission fluids, methanol, ketones, esters. They do not resist to strong acids and basis.
