Delrin® 100AF Blend 13% PTFE Fiber-reinforced Shapes
Delrin® 100AF Blend is a specialized thermoplastic material engineered for demanding applications where low friction, reduced wear, and extended component life are critical. It belongs to the acetal homopolymer family (polyoxymethylene or POM), produced by DuPont under the Delrin® brand, and is commonly used in moving parts such as bearings, gears, rollers, and bushings.
Key Composition and Formulation
- Base Material: A 2:1 blend of Delrin® AF 100 (20% PTFE-filled) and Delrin® 150 (unfilled) resins.
- Filler Content: Uniformly dispersed PTFE (polytetrafluoroethylene) fibers at approximately 13% by weight, which enhances lubricity without compromising core structural properties.
- Color: Naturally dark brown.
- Forms Available: Extruded rods, sheets, and plates for machining into custom components.
Properties and Performance
- Friction and Wear: Exhibits an exceptionally low coefficient of friction (both static and dynamic), minimizing slip-stick behavior. This allows bearings to operate at higher speeds and loads with significantly reduced wear compared to standard Delrin®.
- Strength Retention: Maintains about 90% of the tensile strength, stiffness, and toughness of unmodified Delrin®, while offering better sliding properties.
- Dimensional Stability: Low moisture absorption, resistance to solvents (including gasoline), lubricants, and chemicals, making it suitable for self-threading screws or interference-fit parts.
- Machinability: Excellent, enabling precise fabrication of complex geometries.
- Trade-offs: Slight reductions in impact strength and wear resistance relative to unfilled Delrin® due to the softer PTFE addition, but overall superior for lubricity-focused uses.
Applications
Ideal for non-lubricated or low-maintenance environments in industries like automotive, aerospace, industrial machinery, and consumer products. Examples include high-speed bearings, conveyor components, and valve seats.
Delrin® 100AF 20% PTFE vs Delrin 100AF Blend 13% PTFE
Delrin® 100AF and Delrin® 100AF Blend are both PTFE (polytetrafluoroethylene)-filled acetal homopolymers from DuPont (now DELRIN USA LLC), designed for low-friction, wear-resistant applications like bearings, bushings, and sliding components. They enhance the base Delrin® acetal's properties with PTFE for reduced friction and improved lubricity. The key differences lie in their composition, PTFE content, processing methods, and resulting mechanical trade-offs.

Delrin® 100AF 20% PTFE Fiber-reinforced Shapes
Delrin® 100AF is a high viscosity acetal homopolymer containing 20% PTFE fibers. It is designed for applications requiring low wear and/or low friction against steel, itself, or other plastics.
Key Properties of Delrin 100AF 20% PTFE Fiber-filled POM-H
- Composition: Homopolymer acetal resin uniformly reinforced with 20% chopped PTFE fibers for homogeneous distribution, optimizing sliding friction without compromising core acetal toughness.
- Performance Benefits:
- Superior wear resistance and reduced coefficient of friction compared to unfilled acetal or powder-filled PTFE variants.
- Excellent internal lubrication, eliminating the need for added oils or greases.
- High strength, toughness, and dimensional stability under load.
- Good creep resistance and machinability; minimal stick-slip effects.
- Color: Typically brown (due to PTFE fiber integration).
- Typical Applications: Bearings, bushings, cams, gears, rollers, and other precision components in automotive, industrial machinery, and consumer electronics where low noise, low maintenance, and high cycle life are critical.
This material maintains the inherent chemical resistance, low moisture absorption, and thermal stability of standard Delrin (up to 180°F/82°C continuous use), but the PTFE fibers specifically target tribological (friction/wear) improvements.
Available Shapes and Forms
Delrin 100AF 20% PTFE fiber is supplied as semi-finished "stock shapes" for machining into custom parts. Common forms include:
