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.
Reliable Engineering Thermoplastic for High-Moisture Environments
When traditional metal parts fail due to weight, corrosion, or friction, Acetal (Copolymer POM-C) is a proven engineering material alternative. This high-strength, low-friction thermoplastic performs well in high-moisture environments, delivering the necessary dimensional stability for precision-machined components that must resist warping, swelling, and binding.
Beyond its competitive price point, acetal provides excellent wear resistance and a naturally low coefficient of friction in both dry and wet environments. It machines exceptionally well and resists continuous moisture and a variety of chemicals and solvents, making it a strong choice for many demanding fluid-handling applications.
Looking for different grades or colors? We also offer Black Acetal for improved UV resistance compared to natural acetal and Homopolymer Acetal (Delrin®) for increased mechanical strength to meet specific application requirements.
Why Choose Copolymer Acetal?
Acetal plastic provides reliable performance across diverse mechanical and structural applications. It is the correct choice if your project requires:
Low Moisture Absorption:
Absorbs minimal moisture, ensuring consistent properties and dimensional stability in wet environments with reliable hydrolysis resistance in hot water applications up to 140°F.
High Strength & Stiffness:
Maintains toughness, resilience, and rigidity without becoming brittle, even over long-term exposure to demanding conditions.
Excellent Machinability:
Readily machines to close tolerances using standard high-speed tooling.
Low Friction & Wear:
A smooth, non-porous surface that reduces the need for external lubrication in sliding parts.
Chemical Resilience:
Demonstrates notable resistance to a variety of solvents, basic (high pH) solutions, and hard water.
Copolymer Acetal vs. Delrin® (Homopolymer) vs. Nylon: Which Do You Need?
While all three are engineering plastics, they excel in different operating environments.
Choose Copolymer Acetal (This Sheet) to minimize centerline porosity. The absence of a porous core makes copolymer acetal a popular material choice for food processing and medical applications where hygiene and bacteria growth are concerns. It handles high pH solutions and prolonged hot water exposure better than homopolymer grades.
Choose Delrin® (Homopolymer Acetal) if high room-temperature stiffness, tensile strength, and impact resistance are your primary priorities.
Choose Nylon if you need a tough, abrasion-resistant material for bearings, wear pads, rollers, or parts exposed to repeated impact when moisture absorption is not a concern.
Acetal plastic is a fabrication-friendly material and can be machined using standard woodworking and metalworking tools. It can be readily drilled, cut, and routed. Any machining tool capable of high speed with minimal vibration can be used to achieve tight tolerances and a smooth surface finish.

Technical Performance
Acetal is a rigid engineering thermoplastic designed for applications requiring high dimensional stability, low moisture absorption, and excellent fatigue endurance. Depending on load and environment, acetal can provide consistent performance even in challenging wet conditions.
While Acetal offers excellent machinability and stability, extreme environments and conditions may require different materials:
Strong Acids: Acetal is generally not recommended for environments involving highly concentrated or oxidizing acids. Better Alternative: For extreme chemical or acidic resistance, consider PVC or PTFE (Teflon®).
Sliding Abrasion: While acetal has good wear properties, it may not outlast softer, highly resilient impact plastics in heavy sliding bulk-material scenarios. Better Alternative: For lining chutes and bins requiring maximum sliding abrasion resistance, consider UHMW.
Extreme High Heat: Continuous service above 180°F may reduce mechanical performance and dimensional stability of the material. Better Alternative: For high-heat structural applications, consider PEEK.
