What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.
About this product
Delrin® 900P BK602 is a low-viscosity acetal homopolymer (POM) resin featuring internal lubrication and mold release. This grade is engineered for improved processability, offering excellent flow for filling complex molds while retaining the high strength, stiffness, and low friction that make acetal a premier choice for precision mechanical components and wear-resistant applications.
Key Features & Benefits
- Low Viscosity & High Flow (25 MFR): Enables easy filling of thin walls and complex geometries, reducing injection pressure and cycle times.
- Excellent Stiffness & Strength: Provides high mechanical strength and rigidity for load-bearing components.
- Good Toughness: Offers a balanced impact resistance for durable parts.
- Low Friction & Wear Resistance: Inherently slick and lubricated for moving parts, reducing noise and wear.
- Improved Mold Release: Facilitates easier part ejection from the mold, improving productivity.
Primary Applications
- Gears, Bearings, and Bushings
- Automotive Fuel System Components
- Consumer Appliance Parts
- Fasteners and Clips
- Fluid Handling Components
- Conveyor System Parts
Processing Notes (Injection Molding)
- Drying: Required for 2-4 hours at 80°C. Maximum moisture content should be < 0.20%.
- Melt Temperature: 210 – 220°C (410 – 428°F)
- Mold Temperature: 80 – 100°C (176 – 212°F)

Unedited feedback from customers who reorder Acetal (Delrin) 900P Black Pellets - 2 lbs.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

★★★★★
Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
