What is POM-C UV?
POM-C UV is a black, carbon-black/UV-package stabilized acetal copolymer sold under designations such as Delrin 500P NC010 and Sustarin C UV. It resists outdoor weathering and photodegradation better than natural POM while keeping acetal stiffness and low friction: 64 MPa tensile strength, 30 % elongation, 2.8 GPa modulus, 100 °C maximum service temperature and a machinability score of 88. It is available as moulding pellets, rod and sheet, with GF25, GF30, PTFE20, MoS2, ESD and FDA variants. It cannot be solvent bonded, welds only by hot-plate, vibration, spin or ultrasonic methods, and melt must stay below about 230 °C; natural POM-C is the alternative for indoor parts. POM-C UV has a density of 1.41 g/cm³ (0.0509 lb/in³), heavier than 81% of polymer grades. Its glass-transition temperature is -60°C (-76 °F). POM-C UV has a yield strength of 63 MPa (9.14 ksi) and a tensile strength of 64 MPa (9.28 ksi) — stronger than 74% of polymer grades. Elongation at break is 30% and the elastic modulus is 2.8 GPa (0.406 Msi).

Working with POM-C UV
Is POM-C UV easy to machine?
Excellent to machine — sharp positive-rake carbide, high speed, light feed, and air/mist cooling; avoid part heating and clamp distortion, and anneal 140–150 °C for tight-tolerance parts.
Can POM-C UV be welded?
Poor weldability: hot-plate, vibration, spin and ultrasonic welding work with tuned parameters; solvent bonding is impossible and adhesives need plasma/flame or acid etching.
Can POM-C UV be formed, bent or molded?
Injection mould at 190–215 °C melt / 70–110 °C tool with generous gates and holding pressure; shrinkage ≈2 % and highly anisotropic in filled grades, and melt must stay below ~230 °C to avoid formaldehyde evolution.

What surface finishes work on POM-C UV?
Black UV grade takes a fine machined or bead-blast matte finish; paint and print only after surface pretreatment, and laser marking or in-mould texture is the practical decorating route.

POM-C UV — frequently asked
What is POM-C UV used for?
POM-C UV is typically used for outdoor irrigation fittings, window and door hardware, automotive exterior clips and garden equipment parts. In short: weatherable black acetal; UV-stabilized POM copolymer; machines like unfilled POM.
What is the yield strength of POM-C UV?
POM-C UV has a typical yield strength of 63 MPa (9.14 ksi) and a tensile strength of 64 MPa (9.28 ksi) — stronger than 74% of polymer grades. Strength varies by condition: see the 9 listed tempers.
Is POM-C UV easy to machine?
Yes — machinability is rated excellent (88/100, better than 92% of polymer grades). Excellent to machine — sharp positive-rake carbide, high speed, light feed, and air/mist cooling; avoid part heating and clamp distortion, and anneal 140–150 °C for tight-tolerance parts.
Can POM-C UV be welded?
With care — weldability is rated fair (35/100). Poor weldability: hot-plate, vibration, spin and ultrasonic welding work with tuned parameters; solvent bonding is impossible and adhesives need plasma/flame or acid etching.
What surface finishes work on POM-C UV?
Black UV grade takes a fine machined or bead-blast matte finish; paint and print only after surface pretreatment, and laser marking or in-mould texture is the practical decorating route.

What is the maximum service temperature of POM-C UV?
POM-C UV is rated for continuous use to about 100°C (212 °F), and briefly to 140°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between POM-C UV UV-BK and POM-C UV IM?
UV-BK is the default condition — default outdoor grade: unfilled POM-C with carbon black and light stabilizers for long-term sunlight exposure. IM: use for snap-fits, clips and cold-impact parts where notched toughness is critical. Yield strength is 63 MPa in UV-BK versus 42 MPa in IM.
How much does POM-C UV cost?
POM-C UV is a standard-cost polymer ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
