Key Benefits of POM (Acetal) Engineering Plastic
POM, also known as Acetal or Polyacetal, is chosen for precision components where dimensional accuracy matters over the life of the part. Key benefits include:
- High Dimensional Stability: Holds tight tolerances even under repeated mechanical stress.
- Low Moisture Absorption: Maintains consistent dimensions and performance in humid conditions, unlike Nylon.
- Low Friction: A naturally slick surface suits gears, bearings, and sliding components.
- Fatigue & Creep Resistance: Performs reliably under repeated cyclic loading over long service life.
These properties make POM one of the preferred materials for precision-machined mechanical parts where Nylon’s moisture sensitivity would be a drawback.
Common Applications of POM (Acetal) Engineering Plastic
POM / Acetal is used across precision mechanical and industrial applications, including:
- Precision gears and pinions
- Bearings and bushings
- Conveyor system components
- Valve and pump parts
- Fasteners and small precision-machined parts

Q1. What Is POM (Acetal) Used For?
A. POM, also called Acetal or Polyacetal, is used for precision gears, bearings, bushings, conveyor components, and fasteners that need to hold tight tolerances over long service life.
Q2. How Is POM Different From Nylon?
A. POM absorbs far less moisture than Nylon, so it holds its dimensions more precisely in humid conditions, while Nylon generally offers higher impact resistance.
Q3. What Sizes Of POM Sheets And Rods Do You Stock?
A. We stock POM sheets up to 2000 x 1000mm and rods from 10mm to 300mm diameter, with custom cutting and CNC machining available.
Q4. Do You Offer Custom Machining For POM Parts?
A. Yes, we provide custom cutting to precise dimensions and CNC machining for precision POM components, in addition to standard stock sheets and rods.
Q5. Do You Deliver POM Products Across Saudi Arabia And The GCC?
A. Yes, Diode Trading EST supplies POM sheets and rods across Saudi Arabia and the wider GCC, with material test certificates (MTC) available on request.
