Polyoxymethylene Copolymer (Acetal Copolymer)

Polyoxymethylene Copolymer (POM-C), also known as Acetal Copolymer, is a high-stiffness, low-friction engineering thermoplastic with excellent wear resistance, fatigue endurance, and chemical resistance (especially to bases and hot water).

Typical Grades

ModelModification TypeAdditivesKey Performance IndicatorsMain Application Areas
WL-POM-C-GENStandard Viscosity (General Purpose)StabilizersHigh rigidity, Low friction, Excellent fatigue resistance, Good dimensional stabilityGears, bushings, rollers, conveyor belt parts, pump components, zippers
WL-POM-C-GENHigh Flow GradeStabilizersFaster molding cycles, Easy fill for thin-wall/complex molds, Slightly lower mechanicalsThin-walled parts, complex geometry parts, high-volume production (e.g., lighter casings)
WL-POM-C-IMImpact Modified (Toughened Grade)Impact Modifier, 5-15%Significantly improved impact toughness (esp. notched), Reduced rigidity/hardnessSnap-fit assemblies, clips, fasteners, ski bindings, seatbelt buckles
WL-POM-C-GENPTFE Lubricated GradePTFE Lubricant, 10-20%Extremely low coefficient of friction, Enhanced wear resistance (esp. dry friction)Low friction gears, bearings, sliding elements, actuator parts, self-lubricating precision parts
WL-POM-C-UVUV Stabilized GradeUV Stabilizer, 1-2%Improved weather resistance under outdoor exposure, Delays yellowing/degradationAutomotive interior/exterior parts (limited use), window hardware, outdoor equipment parts
WL-POM-C-GF25Glass Fiber Reinforced GradeGlass Fiber, 10-25%Increased rigidity/strength/creep resistance, Higher HDT, Friction coefficient may increaseStructural parts needing higher rigidity, levers, brackets, gears (needing higher load capacity)
