Nylon
Balls are used in valves, light-duty bearings, flowmeters and
numerous special applications where toughness, abrasion resistance
and light weight are more important than hardness. |

Balls are unaffected by most mild chemicals. They are particularly
outstanding in resistance to alkalies and petroleum oils and
greases. Acids, such as lactic acid, photographic solutions,
etc. have little or no effect. |
