Duracon M90-44: specs and equivalent grades
Daicel (formerly Polyplastics) medium-viscosity acetal copolymer (POM-C). Published data, grades from other producers to ask about, and how to request a quote from one gaylord.
Request a QuoteThe short answer
Duracon M90-44 is a medium-viscosity polyoxymethylene copolymer (POM-C) with a balance of mechanical, chemical and thermal properties. It was a Polyplastics grade: on April 1, 2026 Daicel took the Polyplastics engineering plastics business into Daicel itself, where it runs as Daicel HPP, and Polyplastics USA became Daicel HPP USA. Published melt flow is 9 g/10 min (MVR 8 cm³/10 min), measured at 190°C / 374°F, 2.16 kg, ISO 1133, and density is 1.41 g/cm³ (ISO 1183). Daicel lists tensile modulus 2,700 MPa, notched Charpy 6.0 kJ/m² and HDT 95°C at 1.8 MPa. Grades from other producers to ask about include Celcon M90, Hostaform C9021, Kepital F20-03 and Ultraform N2320 003 AT. They are not identical, so compare the data sheets and run a trial before switching.
Also written as: DURACON M90-44 (Daicel’s capitals). Daicel’s grade database lists it with color codes after the grade, for example CF2001 and CD3068. Quote the full code from your drawing or bag label; color and additive suffixes change the grade.

Grades to ask about instead of Duracon M90-44
These grades from other producers have similar published specs. None is a drop-in replacement: additive packages, flow at molding shear rates, color and approvals differ. If your part, drawing or customer approval names Duracon M90-44, any change needs your approval and usually a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| Celcon M90 | Celanese | MVR 8 cm³/10 min (190°C / 374°F, 2.16 kg, ISO 1133) | 1.41 g/cm³ (ISO 1183) | Tensile modulus 2,760 MPa (ISO 527); flexural modulus 2,550 MPa (ISO 178); notched Charpy 6 kJ/m² (ISO 179); HDT 101°C at 1.8 MPa (ISO 75) | Close match on flow and density. Celanese’s medium-viscosity copolymer for general-purpose molding and thin-wall extrusion. Celcon M90 lists slightly higher stiffness and HDT (101°C vs 95°C at 1.8 MPa); notched impact is the same.

It lists higher stiffness and HDT (104°C vs 95°C) and UL 94 HB only above 1.5 mm, so check the UL file for your wall thickness. Quote this alternative › |

Typical uses for Duracon M90-44
Daicel’s database table gives no application list. What it does show:
- Sliding parts: it is one of the few sheets here that publishes friction and wear data, against carbon steel and against the same grade
- General medium-viscosity acetal copolymer parts
What to check before you switch
- Paperwork after the Daicel merger: new documents and lot paperwork may show Daicel HPP rather than Polyplastics. Ask whether your approval, UL file reference and supplier records need updating.
- Shrinkage: Daicel lists 2.3 % (flow) and 2.1 % (transverse) on a 60 × 60 × 2 mm plaque. Compare with the figures for the grade you run now.
- Wall thickness and flammability: check the UL file for M90-44 at your wall thickness; the Hostaform C9021 sheet lists HB only above 1.5 mm. Check the yellow card for any thin-wall part.
- Gears and sliding parts: compare wear and friction against your actual counterface in a trial. See best plastic for gears.
- Acetal shrinks about 2 % and keeps shrinking slightly after molding. Check dimensions on first articles after any grade change.
- Keep acetal away from PVC in the same barrel and purge thoroughly between them; the two degrade each other.
- Compare melt flow, density and impact only at the same test condition and method (ASTM vs. ISO results differ).
- Ask for the producer’s food-contact or regulatory letter for the exact grade if the part needs one.
- Run a trial lot and check shrinkage, cycle time and appearance before you switch production.
Buying Duracon M90-44: price, lead time and lot size
- Lot size. From one gaylord to a railcar. See gaylord, LTL and truckload for typical weights per box.
- Where it ships from. 22+ partner warehouse locations. Material already in a partner warehouse usually moves sooner than a grade that has to come from the producer; your quote says which applies.
- Price. We do not publish prices because they move with feedstock, freight and order size. What moves your price most: lot size, color, ship-to region, and whether you need Duracon M90-44 itself or can accept a matched alternative. See how resin is priced and the monthly market update.
- Paperwork. Supplier COA on every prime lot (what a COA shows). Ask for the producer’s regulatory letter or UL file if your part needs them.
- Trying an alternative? Start with one gaylord as a trial lot, molded and checked before you commit a full release.
- If Duracon M90-44 itself is not available. Some branded grades are sold only through the producer’s own channels or go on allocation. If we cannot source it, we tell you, then quote a matched alternative with a side-by-side comparison.
Send the grade code, your annual volume and ship-to location. A polymer chemist checks it before we quote; we have been in the resin business for 30+ years. For several grades at once, use the resin RFQ template.
