POM Wear-Resistant Modification: 1–2% PTFE Micropowder for Better Wear Resistance and Easy Demolding

Polyoxymethylene (POM), also known as acetal resin, is widely used in engineering plastics thanks to its excellent mechanical strength, rigidity, and dimensional stability. However, when it comes to applications involving friction, sliding, and frequent contact between moving parts, unmodified POM often shows limitations in wear resistance and mold release. To overcome these challenges, a small amount of PTFE (polytetrafluoroethylene) micropowder is commonly added during the modification process, typically in the range of 1–2%. This simple yet effective formulation significantly improves the performance of POM in demanding applications.

The addition of PTFE micropowder provides multiple benefits. First, it enhances the wear resistance of POM by reducing the coefficient of friction between surfaces. PTFE is well known for its self-lubricating properties, and when evenly dispersed in POM, it creates a microscopic lubricating layer that minimizes abrasion and prolongs service life. This makes modified POM highly suitable for gears, bearings, sliders, and automotive components where long-term durability is critical.

Second, PTFE micropowder improves the mold release properties of POM during injection molding. Unmodified POM sometimes adheres tightly to the mold surface, which not only increases cycle time but also causes surface defects. With the incorporation of 1–2% PTFE micropowder, the resin flows more smoothly and releases more easily, reducing the risk of part sticking and improving production efficiency. This advantage is especially valuable in mass production of precision components, where stable processing and smooth surface finish are essential.

Moreover, the modification does not compromise the mechanical integrity of POM. At low addition levels, PTFE micropowder maintains the inherent strength and rigidity of the polymer while offering additional functional improvements. This balance of properties makes PTFE-modified POM an ideal solution for manufacturers who require both mechanical reliability and superior wear performance.

For industries such as automotive, electronics, consumer goods, and industrial machinery, adopting PTFE-modified POM can bring significant competitive advantages. The ability to deliver components with higher durability, better processing efficiency, and smoother operation helps reduce maintenance costs and enhances end-user satisfaction.
