Premium POM Sheets (Polyacetal / Delrin®) | Imported from Röchling Germany
Engineering applications in precision machinery, automotive manufacturing, and food processing demand dimensional stability, extreme mechanical strength, and minimal friction. High-grade POM Sheets (Polyoxy-Methylene), manufactured by industry leader Röchling Industrial (Germany) and directly imported to Iran, represent the benchmark in technical thermoplastic engineering.
Whether you require POM-C (Copolymer) for enhanced chemical resistance or specialized grades for exact mechanical tolerances, direct sourcing from Röchling guarantees compliance with international standards, consistent molecular density, and long-term durability under heavy mechanical stress.
Technical Specifications & Grade Variations
POM sheets, commonly referred to as Polyacetal or Acetal, are semi-crystalline thermoplastics engineered to replace traditional metallic components in demanding industrial environments.
Key Material Properties
- High Mechanical Strength & Rigidity: Excellent load-bearing capabilities with minimal creep under static or dynamic stress.
- Superior Dimensional Stability: Ultra-low moisture absorption ensures parts retain exact tolerances even in high-humidity or submerged applications.
- Low Coefficient of Friction: Natural self-lubricating surface minimizes wear on mating mechanical parts.
- Exceptional Machinability: Ideal for high-precision CNC turning, milling, and laser cutting without burring or edge cracking.
- Chemical Resistance: Highly resistant to neutral chemicals, solvents, hydrocarbons, and strong alkalis.
POM-C vs. POM-H
- POM-C (Polyacetal Copolymer): The industry standard for versatile industrial engineering. Offers superior resistance to thermal degradation, hot water, and strong alkalis with reduced center-line porosity.
- POM-H (Polyacetal Homopolymer): Provides slightly higher mechanical strength, hardness, and thermal expansion limits for extreme load environments.
Key Industrial Applications
Due to its balance of stiffness, friction performance, and wear resistance, imported Röchling POM sheet stock is widely specified across multiple sectors:
- Precision Mechanical Engineering: Gears, bearings, bushings, guide rollers, and wear strips.
- Automotive Sector: Fuel system components, door lock mechanisms, wiper arms, and sensor housings.
- Electrical & Electronics: Insulating plates, switches, connectors, and structural housings.
- Food & Pharmaceutical Processing: Conveyor components, star wheels, and scraper blades requiring strict regulatory compliance (FDA / EU 10/2011).
- Fluid Management: Valve bodies, pump impellers, manifolds, and hydraulic seals.
Why Choose Imported Röchling POM Sheets?
Not all engineering plastics offer equal internal consistency. Lower-grade polyacetal sheets frequently exhibit internal stress, voiding, and inconsistent thickness tolerances, leading to material warp during high-speed CNC machining.
Machining & Fabrication Guidelines
POM is among the easiest engineering plastics to machine, provided correct tooling parameters are applied:
- Tooling: Sharp high-speed steel (HSS) or carbide tools with positive rake angles.
- Cooling: Air cooling or standard water-soluble cutting fluids prevent localized thermal expansion.
- Chip Removal: Continuous chip removal prevents re-welding onto the workpiece
