Engineering Thermoplastics
POM Homopolymer — Polyoxymethylene Homopolymer
POM homopolymers offer exceptional stiffness, high tensile strength, excellent fatigue endurance, and low coefficient of friction. They have low moisture absorption, good chemical resistance, and inherent lubricity, making them ideal for precise mechanical parts.
