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.
Rigid, Wear-Resistant Delrin® 150 for Precision Machined Parts
Natural Delrin® 150 (Acetal Homopolymer) sheet is an engineering thermoplastic with properties tailored for applications requiring high room-temperature strength, a high modulus of elasticity, and excellent rigidity.
Delrin® 150 features great toughness properties and dimensional stability and performs well across a broad operating temperature range. Its excellent fatigue endurance, low coefficient of friction, and excellent wear properties make it a widely used metal replacement for gears, bearings, bushings, and sliding components.
Natural Delrin® 150 homopolymer is recommended for applications where dimensional stability and machinability are required. It is a good choice if you need:
Low Moisture Absorption:
Absorbs very little moisture, helping parts retain dimensional stability in humid or damp environments.
High Strength & Stiffness:
Highly crystalline structure provides rigidity and resilience, maintaining mechanical integrity and impact resistance under sustained loads in standard operating environments.
Easy Machinability:
Readily machined to close tolerances using standard machining practices and tools capable of high speed without vibration.
Wear Resistance:
Low coefficient of friction offers reliable performance in moving and sliding components.
Delrin® 150 (Homopolymer) vs. Acetal Copolymer vs. Nylon: Which Do You Need?
Delrin® 150, acetal copolymer, and nylon are all engineering plastics, but they excel in different applications.
Choose Delrin® 150 (This Sheet) if high tensile strength, stiffness, and creep resistance are your primary priorities.
Choose Acetal Copolymer if you require a material without centerline porosity, preventing potential routes for leakage of gas and liquids, or areas where bacteria can grow.
Choose Nylon if you need a tough, abrasion-resistant material for bearings, wear pads, rollers, or parts exposed to repeated impact.
Delrin® 150 is highly fabrication-friendly. Available in extruded rod and sheet, it can be processed using standard machining practices with sharp tools, proper support, and controlled cutting conditions. High-speed tooling with minimal vibration helps machinists achieve clean finishes and tight tolerances.

ACENE5 SH
Technical Performance
Natural homopolymer acetal (POM-H) is designed for applications requiring high modulus of elasticity, strength, rigidity, low moisture absorption, and dimensional stability.
Moisture Absorption:
Very low; retains form and dimensional stability in humid or damp environments.
Dimensional Stability:
Highly crystalline structure provides consistent mechanical properties and excellent creep resistance during long-term use in recommended operating conditions.
Friction & Wear:
Low coefficient of friction combined with good toughness properties produces reliable sliding and guiding performance.
Key Properties
High Tensile Strength:
Provides reliable structural integrity for load-bearing mechanical components.
Creep Resistance:
Excellent resistance to cold flow, maintaining shape under static loads.
Centerline Porosity:
A potential characteristic of acetal homopolymer where low-density areas or voids may occur near the centerline. In sheet form, porosity may appear as a line along the center of a cut edge.
Electrical Properties:
Functions well as an insulator for electronic devices and components.
Chemical Resistance:
Offers good resistance to many chemicals and solvents. Note: verification of compatibility for specific operating conditions is encouraged.
Common Industrial Applications
Auto Mechanical: Valves, bearings, gears, sliding elements, housing parts, springs, and conveyor links.
While Delrin® 150 is chosen for its machinability and strength, specific environments may require different formulations or materials:
Fluid Leakage & Bacteria: Centerline porosity in Delrin® 150 can create potential routes for liquid or gas leakage and areas where bacteria may accumulate. Better Alternative: For food processing, sealing components, or fluid environments requiring porosity-free material, choose Acetal Copolymer.
Extreme Abrasive Wear: While Delrin® 150 has a low COF, it is not the most abrasive-resistant plastic available for heavy bulk material handling. Better Alternative: For chute liners or heavy sliding abrasion, consider Virgin UHMW.
High Heat or Prolonged Hot Water: Applications involving elevated temperatures, prolonged hot-water exposure, steam, strong caustics, or high-pH cleaning conditions may require a different material. Better Alternative: For hot water or high-pH cleaning, consider Acetal Copolymer. For dry elevated-temperature wear, consider Heat-Stabilized Nylon. For more aggressive heat or chemical exposure, consider PTFE (Teflon®).
