Key Insight: Creep Resistance<\/strong> \u2014 POM has significantly better creep resistance than nylon. Under sustained loading, POM retains more of its stiffness over time. For components under constant load (spring clips, retaining rings, fastener bushings), POM’s superior creep resistance often makes it the better choice despite similar initial strength.<\/p>\n

\ub0b4\ucda9\uaca9\uc131<\/strong> \u2014 Nylon has higher unnotched impact resistance. But POM often outperforms nylon in notched impact tests because POM’s ductile failure mode absorbs more energy at the crack tip. For parts with stress concentrations (keyways, holes, threads), POM’s toughness at sharp notches is an advantage.<\/p>\n

Fatigue Resistance<\/strong> \u2014 Nylon has superior fatigue resistance for repeated loading. In cyclic loading tests, nylon components survive 3-5\u00d7 more cycles before failure than equivalent POM parts. Critical for components like conveyor belt guides, pump impellers, and hinge mechanisms.<\/p>\n

POM’s thermal weakness<\/strong> \u2014 The 175\u00b0C melting point of POM is its thermal limitation. At temperatures above 100\u00b0C, POM loses mechanical strength rapidly. PA66-GF30 (HDT 250\u00b0C) operates at temperatures where POM would melt.<\/p>\n\n\n\n\n\n

POM wins decisively on moisture<\/strong> \u2014 At 0.8% maximum moisture absorption, POM is essentially dimensionally stable in humid environments. Nylon’s 8-9% absorption causes measurable swelling and property changes. For underwater or outdoor exposed applications without encapsulation, POM is often the only viable choice.<\/p>\n

Critical Decision Points<\/strong>:

\n- Hot water (>60\u00b0C)<\/strong>: Nylon hydrolyzes \u2014 use POM or PVDF
\n- Plasticizer migration<\/strong> (flexible cables, wire insulation): POM absorbs plasticizers \u2014 use PA12
\n- Automotive under-hood<\/strong>: PA66-GF30 for its heat resistance (180\u00b0C+) and fluid resistance
\n- Consumer appliances<\/strong>: POM for its dimensional stability and surface finish<\/p>\n

The critical difference: wear factor<\/strong> \u2014 POM’s wear factor (1-3) is 10-20\u00d7 lower than nylon’s (10-40). This means POM parts generate less heat and wear more slowly in sliding contact. For high-PV applications (bearings, wear strips, sliding inserts), POM is the superior choice.<\/p>\n

Self-lubricating versions<\/strong>:
\n- POM + PTFE<\/strong>: Wear factor drops to 0.5-1.0 \u2014 excellent for boundary lubrication
\n- PA6\/66 + PTFE or silicone<\/strong>: Significantly reduces friction, but PTFE can migrate to surface and affect bonding
\n- Carbon fiber reinforced<\/strong>: Improves wear resistance in both materials, especially at elevated temperatures<\/p>\n

Surface Speed Consideration<\/strong>: At surface speeds above 1 m\/s in dry sliding, both materials generate enough heat to cause thermal softening. For high-speed applications, consider internally lubricated grades or oil-impregnated sintered bronze backings.<\/p>\n
