Description

Polyoxymethylene (POM) is a high-performance engineering thermoplastic known for its exceptional stiffness, low friction, and excellent dimensional stability. This material is critical for manufacturers requiring durable, wear-resistant components with reliable mechanical properties over a wide temperature range. Key industries that utilize POM include automotive, consumer electronics, industrial machinery, and medical device manufacturing for precision parts.

Application

• Precision Mechanical Components: Gears, bearings, bushings, and cams in automotive and industrial equipment.
• Consumer Goods and Electronics: Housings, rollers, fasteners, and zippers requiring smooth operation and durability.
• Fluid Handling Systems: Pump housings, valve bodies, and meter components due to its chemical resistance.
• Medical Devices: Components for inhalers, drug delivery systems, and surgical instruments where precision and biocompatibility are needed.
• Electrical Insulation: Connectors, insulators, and switch components.
• Aerospace and Defense: Lightweight, high-strength parts for control systems and assemblies.
