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.
FDA-Compliant Fluoropolymer for Extreme Heat and Chemicals
Natural Virgin PTFE (Polytetrafluoroethylene) sheet—also known by the brand name Teflon®1—is a high-performance fluoropolymer made for extreme environments where other plastics fail. Offering nearly universal chemical immunity and continuous stability from -400°F to +500°F, it is an exceptional choice for for critical sealing and non-stick applications.
Looking for enhanced mechanical properties? For applications requiring higher compression strength and reduced cold flow, we offer Glass-Filled PTFE and Mechanical Grade PTFE options.

Why Choose Virgin PTFE Sheet?
Virgin PTFE is the purest form of the material, containing no additives or reprocessed material. This ensures maximum electrical insulation and FDA compliance. It is the correct choice if you need:
Universal Chemical Resistance:
Virtually unaffected by all acids, bases, and solvents, making it essential for chemical processing.
Extreme Temperature Range:
Remains stable and functional in environments ranging from cryogenic temperatures up to 500°F (260°C).
Lowest Friction Coefficient:
The "slickest" solid material available, preventing "stick-slip" and ensuring easy release in food or adhesive applications.
FDA & Medical Grade:
This natural virgin grade is non-toxic and compliant for food contact and medical equipment components.
Excellent Dielectric Strength:
An outstanding insulator for high-frequency electrical applications, including aerospace and computer hardware.
Virgin vs. Mechanical Grade PTFE: Which Do You Need?
While virgin and mechanical grades of PTFE look similar, their internal composition produces distinct peformance differences:
Choose Virgin PTFE (This Sheet) for food contact, medical applications, or high-end electrical insulation. It has the highest purity, the best physical properties, and the lowest friction.
Choose Mechanical Grade for non-critical gaskets or spacers where cost is the primary factor. It contains reprocessed material and is not FDA compliant.
Fabrication & Machining
PTFE is easily cut, drilled, and routed, though its softness requires exceptionally sharp tooling to prevent deformation.
Engineering Note: PTFE is a "cold-flow" material that may creep under constant, heavy loads. If dimensional stability under high pressure is required, use Glass-Filled PTFE.

Technical Performance
Natural Virgin PTFE (Polytetrafluoroethylene) is a high-performance fluoropolymer engineered for extreme environments requiring near-universal chemical immunity, wide temperature stability, and the lowest possible friction.
Unmatched operating range of -400°F to 500°F. It maintains flexibility at cryogenic temperatures and structural integrity in high-heat environments.
Chemical Immunity:
Practically inert to all known chemicals, solvents, and corrosive agents, except for molten alkali metals and elemental fluorine.
Friction Coefficient:
The lowest of any solid material (0.05–0.10 static), providing a permanent non-stick surface that eliminates "stick-slip" in mechanical assemblies.
Key Properties
FDA Compliant:
Natural Virgin grade is non-toxic and approved for direct food contact (CFR 177.1550) and medical applications.
Dielectric Strength:
Excellent electrical insulation properties with high dielectric strength and a low dissipation factor, even at high frequencies.
Zero Moisture Absorption:
Completely hydrophobic; it will not swell, degrade, or harbor bacterial growth in wet or submerged conditions.
Weather & UV Resistance:
Totally resistant to UV radiation and oxidation, making it suitable for indefinite outdoor exposure without degradation.
Flame Retardant:
Inherently non-flammable with a high limiting oxygen index (LOI), making it safe for critical aerospace and industrial hardware.
Common Industrial Applications
Fluid Handling: Chemically inert gaskets, valve seats, pump components, and seals for aggressive chemical processing.
Electrical & Aerospace: High-temperature wire insulation, standoff insulators, and connector assemblies for flight and satellite hardware.
Food & Medical: Non-stick release sheets, pharmaceutical filling equipment components, and medical lab instrumentation.
Mechanical Wear: Slide plates, expansion joints, and low-speed bushings where external lubricants cannot be used or would contaminate the process.
Engineering Limitations & Alternatives
While PTFE is the high-performance choice for chemical and thermal resistance, its physical softness may require alternatives for high-load mechanical use:
Mechanical Strength: Virgin PTFE is susceptible to "cold flow" (deformation under load). Better Alternative: For high-load compression applications, choose Glass-Filled PTFE.
Structural Rigidity: PTFE is a soft plastic and cannot be used for structural frames or high-torque gears. Better Alternative: For rigid, chemically resistant parts, consider PEEK.
Impact Wear: While slick, PTFE is less resistant to abrasive impact than certain polyethylenes. Better Alternative: For heavy impact abrasion in ambient temperatures, consider Natural Virgin UHMW.
