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.
Black PEEK Sheet for High-Temperature, Chemically Resistant Components
Black PEEK (Polyether Ether Ketone) sheet is an unfilled, black-pigmented high-performance thermoplastic with outstanding chemical resistance, thermal stability, and mechanical toughness. Black PEEK is a popular choice for visible assemblies, component masking, improved contrast, or applications where an unfilled black stock shape is favored.
With a maximum continuous working temperature of up to 480°F, Black PEEK can serve as a lightweight, corrosion-resistant replacement for metal and stainless steel components. Its structural integrity under extreme heat and pressure makes it a dependable choice for industrial applications where long-term performance is a priority.
Black PEEK is an advanced thermoplastic that reduces the risk of failure in demanding operating environments. It is the correct choice for applications where you need:
Extreme Thermal Resilience:
Features a long-term service temperature of up to 480°F in air and retains its mechanical properties effectively even in steam or high-pressure water environments.
Broad Chemical Resistance:
Exhibits excellent resistance to a wide array of chemicals and hydrolysis and is insoluble in most common industrial solvents.
High Strength and Stiffness:
Provides the mechanical performance needed for precision components subjected to sustained loads and elevated operating temperatures.
Wear Resistance:
Delivers good sliding performance and wear resistance (bearing-grade PEEK may be preferred for more demanding PV applications).
Black PEEK vs. PTFE: Which Do You Need?
While both are considered high-performance plastics that endure harsh chemicals and extreme heat, they are specified for different applications.
Choose Black PEEK (This Sheet) if your application demands high mechanical strength, rigidity, and the ability to support dynamic or static loads at elevated temperatures.
Choose PTFE if you need an exceptionally low coefficient of friction or broad chemical resistance, but do not require structural load-bearing capabilities.
Fabrication & Machining
Black PEEK offers excellent machinability but requires careful thermal management during fabrication. For precise, high-tolerance components, sharp carbide tooling, appropriate feeds and speeds, and coolant or air cooling may be required to control heat buildup.

Technical Performance
Black PEEK is a high-performance material preferred for applications requiring superior mechanical, thermal, and electrical properties. It is highly resistant to thermal degradation and provides excellent dimensional stability under stress.
Has a long-term service temperature of up to 480°F in air and retains its mechanical properties effectively in steam or high-pressure water.
Wear Resistance:
Features good general-purpose sliding and wear performance.
Mechanical Performance:
Combines high strength, stiffness, and dimensional stability for precision components subjected to demanding mechanical loads.
Key Properties
Chemical Resistance:
Resistant to a broad range of organic and inorganic liquids and insoluble in most common solvents.
Hydrolysis Resistance:
Designed to reduce the risk of degradation from prolonged exposure to high-pressure steam environments.
Fatigue Resistance:
Excellent fatigue resistance promotes mechanical longevity when components are subjected to cyclic loading.
Common Industrial Applications
Mechanical Components: Machined valve, seal, and selected bearing components.
Scientific & Analytical Equipment: Instrument parts, valve components, and precision-machined components exposed to heat or chemicals.
Aerospace Components: Machined parts for aircraft systems where low weight, heat resistance, and chemical resistance are important.
Industrial Processing: Utilized extensively in general chemical process applications and fluid handling.
Engineering Limitations & Alternatives
While Black PEEK is a high-performance material, specific operating environments or budget constraints may dictate the use of alternative materials:
Cost & Moderate-Temperature Service: PEEK is a premium high-performance material designed for extreme environments and may be cost-prohibitive when an application does not require the full range of its capabilities. Better Alternative: For cost-effective precision components operating consistently under 180°F, consider Acetal.
Transparent Guards & Impact Barriers: Black PEEK is not intended for applications that require a transparent panel or a large, cost-effective impact-resistant barrier. Better Alternative: For machine guards, viewing panels, and protective barriers requiring very high impact resistance, consider Polycarbonate.
Extremely Low Friction at Moderate Temps: If load-bearing structural strength is not required and the sole design priority is chemical inertness alongside low sliding friction, other materials may be more cost-effective. Better Alternative: For applications requiring extreme low friction properties, consider PTFE.
