POM Grades Injection Molding Properties And Applications
Delrin® (General-Purpose POM)
Delrin® is a versatile general-purpose POM known for its high stiffness, excellent dimensional stability, and ease of machining. With a 1.42 g/cm³ density, it boasts a tensile strength of up to 85 MPa and a flexural modulus of 3.2 GPa. This makes it ideal for gears, bushings, fasteners, and various automotive components. Its resistance to wear, chemicals, and moisture ensures durable performance.
Delrin® AF (Filled POM with PTFE)
Delrin® AF combines POM with PTFE to create a low-friction material that offers wear resistance and a coefficient of friction as low as 0.12. With a density of 1.47 g/cm³, it maintains a tensile strength of up to 78 MPa and a flexural modulus of 3.1 GPa. Bearings, bushings, conveyor systems, and moving parts benefit from reduced friction.
Delrin® 570 (FDA-Compliant POM)
Delrin® 570 is an FDA-compliant POM with a 1.41 g/cm³ density. It offers a tensile strength of up to 75 MPa and a flexural modulus of 2.8 GPa. Its suitability for food processing equipment, medical devices, and conveyor belts arises from its good chemical resistance and compliance with stringent FDA regulations.
Hostaform® (Engineering POM)
Hostaform® is an engineering-grade POM valued for its high strength, even at elevated temperatures. With a density of 1.42 g/cm³, it boasts a tensile strength of up to 75 MPa and a flexural modulus of 3.2 GPa. Automotive parts, precision gears, and electrical components benefit from their exceptional mechanical properties, including resistance to wear and fatigue.
Celcon® (Low-Friction POM)
Celcon® is a low-friction POM designed for applications requiring minimal wear and reduced friction. With a 1.42 g/cm³ density, it maintains a tensile strength of up to 77 MPa and a flexural modulus of 3.2 GPa. Its unique combination of low friction, high wear resistance, and dimensional stability makes it ideal for low-friction bearings, conveyor components, and pump parts.
