Zeolite ZP-4A powder
...................................................................

Zeolite ZP 4A is a Sodium aluminiumsilicate. Due to its ion exchanging properties, it is used as builder in phosphate-free and phosphate-reduced detergents.
In addition to standard Zeolite ZP-4A powder, the modified Zeolite ZP-4A M powder with excellent flow characteristics is avail­able.
