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.
Impact-Resistant Polycarbonate With 2-Sided Abrasion Protection
Clear Polycarbonate AR2 sheet combines polycarbonate's impact strength and transparency with an abrasion-resistant hardcoat on both sides. Compared with uncoated general-purpose polycarbonate, this hardcoated sheet has better resistance to scratching, marring, chemical contact, and outdoor weathering.
This grade sees use in many applications, including flat glazing, machine guards, equipment windows, protective panels, and other transparent parts whose surfaces may be exposed to frequent cleaning or physical contact. AR2 retains polycarbonate's light weight and impact resistance while adding a harder, more durable viewing surface.
"AR2" means that both faces have an abrasion-resistant hardcoat. The sheet retains polycarbonate-level impact performance while resisting surface wear better than a standard uncoated sheet. Choose it when your application needs:
Two-Sided Abrasion Resistance:
The hard-coated faces resist marring and abrasion substantially better than uncoated polycarbonate.
High Impact Strength:
The sheet retains polycarbonate's inherent toughness for protective glazing and guards, including transparent equipment panels.
Clear Visibility:
The sheet provides clear visibility of equipment, processes, or enclosed areas.
Enhanced UV & Weathering Resistance:
The AR2 hardcoat helps improve long-term outdoor weathering performance and resistance to yellowing compared with unprotected polycarbonate.
Improved Surface Chemical Resistance:
Tolerates a wider range of cleaning and chemical contact than uncoated polycarbonate surfaces. Note: cut edges remain uncoated.
AR2 vs. Standard Polycarbonate: Which Do You Need?
Both provide polycarbonate impact strength and transparency, but they differ in surface performance and fabrication requirements.
Choose AR2 Polycarbonate (This Sheet) when both exposed faces need better protection from surface wear and chemical contact, along with added weathering resistance. It is particularly useful for frequently cleaned glazing, machine guards, and protective viewing panels.
Choose Standard Polycarbonate when abrasion resistance is less important or the sheet must be cold-bent or formed. Uncoated grades offer more fabrication flexibility at a lower material cost.
Fabrication & Machining
Clear Polycarbonate AR2 can be cut, drilled, routed, or milled with appropriate plastic-fabrication tooling. Sharp carbide tools and controlled feeds help limit localized heating and preserve edge quality. Conventional hard-coated AR polycarbonate is intended for flat applications and should not be cold-formed like standard uncoated polycarbonate. Machining exposes uncoated edges, so evaluate chemical exposure at those edges separately.

POLCEZ SH
Technical Performance
Clear Polycarbonate AR2 is a transparent polycarbonate sheet with a hardcoat on both sides. It is designed for flat applications that require high impact strength and better resistance to abrasion, surface marring, chemical contact, and outdoor weathering.
An abrasion-resistant hardcoat on both faces improves surface hardness and resistance to repeated contact compared with uncoated polycarbonate.
Impact Performance:
The sheet retains polycarbonate's high impact strength while adding a harder protective surface for transparent guarding and glazing.
Thermal Performance:
Has a typical heat deflection temperature of approximately 270°F at 264 psi under ASTM D648.
Key Properties
Abrasion Resistant:
The hard-coated surfaces provide substantially better resistance to scratching, marring, and haze development than standard uncoated polycarbonate.
Enhanced UV Resistance:
The sheet is designed for improved outdoor weathering and reduced yellowing compared with unprotected polycarbonate.
Optical Clarity:
Its transparent construction maintains clear visibility for glazing, viewing windows, machine guards, and protective panels.
Electrical Insulation:
Polycarbonate has strong dielectric properties and is used in applications that require transparent or fabricated electrical insulating components.
Lightweight:
Polycarbonate weighs considerably less than glass while retaining strong impact performance.
Common Industrial Applications
Machine Guarding: Clear equipment guards, safety windows, and enclosure panels exposed to cleaning, handling, or repeated surface contact.
Architectural Glazing: Flat transparent panels where impact resistance, visibility, abrasion resistance, and outdoor weatherability are important.
Protective Viewing Panels: Windows and barriers for equipment, public-facing installations, transportation, and other areas subject to wear or incidental impact.
Laminated Assemblies: Transparent laminate constructions that benefit from a durable, abrasion-resistant exterior polycarbonate surface.
Engineering Limitations & Alternatives
Clear Polycarbonate AR2 is designed primarily for flat, abrasion-resistant glazing and guarding. Applications that require forming, certified ballistic protection, or different optical surface priorities may need another grade:
Cold Forming: Conventional hard-coated AR2 polycarbonate is intended for flat applications and should not be cold-bent like uncoated general-purpose sheet. Better Alternative: For fabricated panels that require cold bending or forming, consider Clear General-Purpose Polycarbonate.
Ballistic Protection: High impact strength does not make standard AR2 sheet a certified bullet-resistant glazing material. Ballistic applications require a tested laminate with the appropriate threat rating. Better Alternative: For UL 752-rated ballistic glazing, choose AZCARB BR Bullet-Resistant Polycarbonate.
Material Tradeoff: AR2 polycarbonate combines high impact strength with improved surface durability, but it is not scratch-proof or mechanically identical to glass. Better Alternative: When high impact resistance is less important and greater rigidity and optical clarity are preferred, consider Clear Cast Acrylic. Standard cast acrylic is not hard-coated and can still scratch.
