As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade.Please review our full return and shipping policy here.
Measure Twice, Cut Once
Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring Tape
Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End Hook
The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).
Sanitizing Acrylic and Polycarbonate Sheet [X]
Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.
Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.
Modified Acetal With Reduced Friction & Enhanced Wear Life
Acetal 13% AF Blend sheet combines Acetal AF-100 and Acetal 150 resins in a 2:1 ratio. It is intended for parts that need better sliding and friction properties while retaining reliable mechanical strength.
Softer PTFE fibers give this dark brown Acetal AF blend lower friction and reduced wear. Its static and dynamic coefficients of friction are closer to each other than those of most standard plastics, helping minimize stick-slip in demanding sliding, bearing, and wear applications.
Looking for an unmodified grade? We also stock Natural Acetal and Black Acetal for parts where higher strength and stiffness matter more than reduced friction.
Why Choose Acetal 13% AF Blend?
This blend adds the lubricity of PTFE while retaining much of acetal's strength and stiffness. Key benefits include:
Reduced Friction:
PTFE fibers within the sheet help lower friction in sliding mechanisms and guide components.
Wear Resistance:
Enhanced wear resistance reduces wear in bushings and other moving components exposed to repeated sliding.
Reduced Stick-Slip:
The closer relationship between the static and dynamic coefficients of friction helps reduce jerky startup and supports smoother movement.
Mechanical Performance:
Retains much of the strength and stiffness of unmodified acetal while providing lower friction and better sliding performance.
Moisture Resistance:
Like standard acetal, this blend absorbs minimal moisture, helping precision parts maintain excellent dimensional stability in wet or humid environments.
Acetal AF Blend vs. Unfilled Copolymer Acetal: Which Do You Need?
Both materials offer excellent dimensional stability and machinability, but they suit different mechanical requirements.
Choose Acetal AF Blend (This Sheet) when reducing friction, avoiding stick-slip, and extending wear life in moving parts are the priorities.
Choose Unfilled Copolymer Acetal when you need higher strength and stiffness than PTFE-filled Acetal AF Blend and do not need the added lubricity of PTFE.
Fabrication & Machining
Acetal 13% AF Blend machines well with standard tools for precision gears, bushings, and sliding components. Its PTFE fiber content improves lubricity while retaining much of the strength and machinability of unmodified acetal.

Technical Performance
Acetal 13% AF Blend pairs reliable mechanical strength with modified sliding and friction properties intended to reduce wear in moving components.
Friction Properties:
Its static and dynamic coefficients allow for reduced stick-slip behavior.
Wear Resistance:
This blend is formulated so bearings and sliding elements can operate with less wear than standard acetal.
Mechanical Strength:
Despite the addition of softer PTFE fibers, the blend maintains excellent structural integrity, retaining much of the strength of unmodified acetal.
Key Properties
Material Composition:
A 13% PTFE-filled acetal material produced from a 2:1 blend of Acetal AF-100 and Acetal 150 resins.
Visual Appearance:
This formulation's natural color is dark brown.
PTFE Fiber Addition:
Incorporates softer PTFE fibers that modify certain mechanical properties, favoring lubricity over absolute rigidity.
Common Industrial Applications
Bearings & Bushings: Machined components designed for lower friction, smoother motion, and reduced wear.
Sliding & Guiding Components: Wear strips, guide rails, slides, thrust washers, and other parts exposed to repeated sliding contact.
Power-Transmission Components: Gears, rollers, cams, and related moving parts that benefit from dimensional stability and modified friction properties.
Conveyor & Packaging Equipment: Guides, rollers, wear components, and other moving parts where reduced friction may lower operating resistance and maintenance requirements.
Valve & Mechanical Components: Seats, seals, spacers, and precision parts with moving or sliding interfaces.
Engineering Limitations & Alternatives
Acetal 13% AF Blend suits many moving parts, but some operating conditions call for other materials:
Maximum Structural Strength: PTFE fibers improve lubricity and wear performance but reduce the material's strength. Better Alternative: For structural gears or parts requiring maximum rigidity and load-bearing capacity, choose unmodified Acetal.
High-Temperature Environments: Acetal resins have defined continuous service temperature limits and are not classified as extreme-heat materials. Better Alternative: For high-heat, low-friction applications with lighter loads, consider PTFE. Note: PTFE has lower structural strength. For high heat and high loads, explore PAI or PEEK.
