ECO PA is cast polyamide with good sliding properties and is used for back -up rings, guide rings and bearing components instead of POM fora diameters above 260 mm. Ecomid can be used in mineral oils and water-based fire-resistant hydraulic fluids. When designing parts out of ECO PA for an application in water or water-based fluids, the swelling of the material (ECOPA abosorbs water up to eight weight percent) must be taken into account.
