Trusted by engineers worldwide, Ailide Polymer (Jiangsu) Co., Ltd. brings you the POM FM090AW PTFE Filled Wear Resistant Low Friction Acetal – a high-performance engineering plastic specifically formulated for silent gear applications. As a dedicated manufacturer with a 1,000–3,000 sqm facility and over a decade of compounding expertise, we understand that noise reduction and long-term durability are critical in gears, bushings, and sliding components. This PTFE‑filled acetal grade delivers an exceptionally low coefficient of friction while maintaining the inherent strength and stiffness of standard POM, making it ideal for applications where metal replacement, reduced wear, and quiet operation are required.
Key Features & Technical Specifications
PTFE Lubrication: Evenly dispersed micro‑PTFE particles create a permanent internal lubricant, reducing friction without external grease.
Wear Resistance: Enhanced surface durability extends component life by 2–3 times compared to unfilled acetal in sliding/rotating contact.
Low Noise Operation: The self‑lubricating nature eliminates stick‑slip, resulting in smooth, silent gear meshing.
Dimensional Stability: Low moisture absorption (0.2% max) ensures consistent part geometry in humid environments.
Machinability: Can be easily turned, milled, drilled, and tapped to tight tolerances.
Chemical Resistance: Excellent resistance to hydrocarbons, alcohols, and weak acids/alkalis.

Customer Benefits:
Silent gears: Perfect for office equipment, printers, small appliances, and automotive interior actuators where noise is a concern.
Reduced maintenance: No external lubrication needed; PTFE does not dry out or attract dust.
Cost savings: Lower weight than metal gears, faster molding cycles, and no secondary oiling operations.
Customizable: Available in rod, sheet, or custom‑cut blanks. Color options upon request (natural, black, blue).

Frequently Asked Questions (FAQ)
What is the main difference between standard POM and this PTFE‑filled grade?
Standard POM has a friction coefficient of ~0.3; FM090AW with PTFE reduces it to ~0.14, dramatically lowering noise and wear in sliding contact.Can this material be used for high‑speed gears?
Yes, the low friction and heat dissipation make it suitable for moderate to high‑speed applications as long as the PV limit (pressure × velocity) is respected. For extreme speeds, consult our engineering team.Is the PTFE filler food‑grade compliant?
Our standard grade does not carry food‑contact certification. If needed, we can discuss a food‑grade variant (custom formulation available upon request).Does the PTFE filler affect the machinability?
No – it actually improves chip breaking and reduces tool wear compared to unfilled POM, making it easier to achieve tight tolerances.What sizes are available in rod and sheet?
Rods: diameter 6 mm to 200 mm; sheets: thickness 2 mm to 50 mm, width up to 600 mm. Custom sizes can be cut to order.How does the material behave in wet environments?
Moisture absorption is very low (0.15% at saturation), so dimensional stability remains excellent even in high‑humidity conditions.Can I use this acetal for worm gears or rack‑and‑pinion systems?
Absolutely. Its low friction and high wear resistance make it ideal for all types of gear meshing, especially where quiet operation is required.Is a certificate of compliance or test report provided for each shipment?
Yes, we can provide a material test report (MTR) upon request, including density, tensile, and friction data for the specific batch.
