Frequently Asked Questions
Delrin AF is a PTFE- fiber or powder filled homopolymer acetal material designed to reduce friction and improve wear resistance. Compared to standard Delrin, Delrin AF offers smoother sliding performance, longer wear life, and quieter operation in motion applications.
Delrin AF is typically chosen for sliding, rotating, and wear-critical components where low friction, smooth motion, and long service life are more important than high temperature or chemical resistance.
Quantum AEP provides several specialized Delrin grades tailored for specific friction and wear requirements:
- DE588: A naval-grade acetal developed for submarine components. It features 20% PTFE fibers and is uniquely conformable for sealing applications.
- 100AF / AF13: High-performance grades utilizing PTFE fibers (20% and 13% respectively) for superior lubricity in general dry-running environments.
- Delrin-PTFE 13P: A cost-effective solution using 13% PTFE powder to provide enhanced wear resistance and reduced friction for high-volume or light-duty applications.
Yes. Delrin AF machines cleanly and predictably using standard machining practices. It supports tight tolerances and consistent surface finishes, making it suitable for precision wear and motion components.
Quantum AEP supplies Delrin AF as extruded rods, plates, and tubular bars to support a wide range of machined wear and motion component designs.
In many applications, Delrin AF can operate without external lubrication due to its PTFE-filled formulation. However, lubrication requirements depend on load, speed, and operating conditions.
Delrin AF is commonly used for bushings, bearings, wear pads, guide rails, gears, conveyor components, and other parts requiring low friction and long-term wear resistance.
