Cast Nylon Unfilled

Cast Nylon Unfilled

Cast Nylon Unfilled Overview

What is the Material: Cast Nylon Unfilled is a semi-crystalline material. The PA-6 naming comes from the base material consisting of the 6 carbon molecule caprolactum.

Key Material Features: This material is beneficial in applications requiring mechanical properties, low friction, wear resistance, abrasion resistance, and dimensional stability.

Other Considerations: Cast nylons are often used as wear parts. The properties of the materials often make them beneficial alternatives to steel and bronze parts.
