Material Comparison: Nylon vs. UHMW vs. Acetal

Choosing the right material can make or break your product's performance. Here's a quick engineering comparison to help guide your selection:

PropertyNylon (PA)UHMW (Ultra-High Molecular Weight PE)Acetal (POM/Delrin)
Density (g/cm³)~1.14~0.93~1.41
Tensile Strength (MPa)70–9020–4060–70
Impact ResistanceModerateExcellentGood
Moisture AbsorptionHighVery LowLow
Coefficient of FrictionModerateVery LowLow
MachinabilityGoodExcellentExcellent
Temperature Range (°F)-40 to 250-150 to 180-60 to 180
Chemical ResistanceModerateExcellentGood
CostModerateLowModerate to High

Note: Values are approximate and can vary by grade and supplier.

This chart helps customers understand why UHMW is ideal for your niche-and why you're the right partner to guide material selection.
