Polyetheretherketone (PEEK) is a linear, aromatic, semi-crystalline polymer that exhibits excellent mechanical and thermal properties. Several grades of PEEK™ such as Virgin PEEK™, 30% Glass Filled PEEK™, 30% Carbon Filled PEEK™, and Bearing Grade PEEK™ are preferred for applications in demanding environments. PEEK rods, sheets, and machine parts are sought after for applications across industries. This post aims to discuss PEEK’s properties and benefits, which in turn helps you use the material wisely in applications.
