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 HPV is a high-performance bearing grade sheet designed for applications requiring excellent wear, slide, and mechanical properties. Reinforced with carbon fiber, this advanced thermoplastic is engineered to offer a very low coefficient of friction (COF) and high machinability among PEEK grades.
PEEK HPV is formulated to run at higher speeds and handle heavier loads than standard unfilled PEEK, maintaining dimensional stability even in environments where it will be continuously exposed to hot water or steam. It serves as a highly effective replacement for metal in demanding components such as bearings and bushings.
Looking for standard, unfilled options? For applications that do not require internal lubricants or carbon fiber reinforcement, we offer Natural Virgin PEEK.
Why Choose PEEK HPV?
This is a specialized bearing grade material reinforced with carbon fiber. It is ideal for environments requiring extreme thermal stability and continuous load-bearing capabilities. PEEK HPV is the correct choice if you need:
Outstanding Wear Properties:
Features internal graphite and PTFE lubricants for enhanced lubricity, allowing it to run effectively with or without external lubricants.
Thermal Stability:
Offers high-temperature performance, with continuous service capability approaching 500°F depending on load, environment, and application conditions.
Low Friction:
Designed to provide the lowest coefficient of friction among all PEEK grades.
Chemical Resistance:
Outstanding resistance to a wide range of chemicals, hydrolysis, and superheated steam.
High Creep Resistance:
Maintains structural integrity and dimensional stability under persistent mechanical stress.
PEEK HPV vs. Standard PEEK: Which Do You Need?
While both are high-performance, semi-crystalline thermoplastics, they are utilized in different mechanical environments.
Choose PEEK HPV (This Sheet) if load-bearing wear life and self-lubrication are your priorities. The internal lubricants and carbon fiber make it suitable for high-speed, high-friction components.
Choose Standard PEEK if you require a high-purity, unfilled polymer for general structural applications or environments where carbon reinforcement is unnecessary.
Fabrication & Machining
PEEK HPV offers some of the best machinability among PEEK grades. Due to its structural stability, it supports the tight tolerances required in demanding aerospace, automotive, and textile components.

Key Properties
Bearing Grade Capability:
Carbon fiber reinforcement enables the material to handle heavier loads and higher speeds than standard PEEK formulations.
Chemical Stability:
Outstanding resistance to chemicals; effectively resists hydrolysis and continuous exposure to hot water or superheated steam.
Creep Resistance:
High creep resistance ensures dimensional stability is maintained under prolonged stress.
Flammability:
PEEK HPV is inherently flame resistant; this sheet carries a UL94 rating of V-0.
Machinability:
Formulated to offer excellent machinability compared to other filled PEEK grades, supporting precision engineering tasks.
Common Industrial Applications
Mechanical Engineering: Wear components, high-load bearings, and bushings replacing traditional metal parts.
Chemical Technology: Seals, valves, and pump components exposed to harsh chemicals or superheated steam.
Aerospace & Automotive: Precision structural components operating in extreme heat and high-friction environments.
Textile Industry: High-speed sliding parts and guides requiring self-lubricating properties.
Engineering Limitations & Alternatives
While PEEK HPV is a premier high-performance material for severe environments, specific applications may allow for more cost-effective or differently optimized materials:
Cost vs. Operating Environment: PEEK HPV is an advanced material. If operating temperatures stay below 200°F and extreme chemical resistance is not required, its capabilities may exceed project needs. Better Alternative: For standard-temperature, high-load bearings or structural gears, choose Cast Nylon or Acetal (Delrin®).
Unfilled Requirements: Because it contains carbon fiber, graphite, and PTFE, it is not suitable for applications requiring high-purity, unfilled polymers. Better Alternative: For high-temperature structural needs without additives, consider Natural Virgin PEEK.
Absolute Chemical Inertness: While PEEK is highly resistant to most chemicals, certain highly specific or volatile chemical environments may require fully fluorinated solutions. Better Alternative: For applications requiring very broad chemical compatibility, consider PTFE (Teflon®).
