Delrin POM-H — Machining & Properties
Typical properties, what Delrin POM-H is like on a machine tool, what it gets used for, and the tolerance and finishes we hold on it — from a shop that actually machines it, not a datasheet aggregator. Every figure here drives our own calculators.
Machining Delrin POM-H
Machinability is rated excellent — one of the friendlier materials on a machine tool — expect efficient cycle times and good surface finish at sensible cost. Engineering polymers have significantly higher thermal expansion coefficients than metals. All plastic components must be inspected at a controlled temperature, and tolerances tighter than ±0.020 mm are generally not maintainable in service without dimensional constraints in the design.
Our standard achievable tolerance on Delrin POM-H is ±0.020mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Higher crystallinity than POM-C. Full material traceability with MTR and CoC documentation on every order.
Typical applications
High-stiffness components, precision bushings, positioning elements.

Delrin POM-H — FAQ
What is the density of Delrin POM-H?
1.42 g/cm³ (typical). That is 1420 kg/m³ — our metal weight calculator uses exactly this figure for Delrin POM-H.
What is the tensile strength of Delrin POM-H?
Typically 65 MPa. Treat it as a typical value, not a specification — the Material Test Report supplied with your order states the actual certified figures for the batch.
Is Delrin POM-H easy to machine?
Its machinability is rated excellent — one of the friendlier materials on a machine tool — expect efficient cycle times and good surface finish at sensible cost.
What is Delrin POM-H used for?
Typical applications: High-stiffness components, precision bushings, positioning elements.
What tolerance can be held when machining Delrin POM-H?
Our standard achievable tolerance on Delrin POM-H is ±0.020mm under normal conditions (ISO 2768-f general tolerancing). Tighter tolerances on critical features can be agreed at quotation for specific geometries.
Can Dalloway machine Delrin POM-H?
Yes — we machine Delrin POM-H in-house on 3, 4 and 5-axis milling and CNC turning, from single prototypes to production, with MTR and CoC documentation standard. Typical finishes: Higher crystallinity than POM-C.
