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.
Copolymer Polypropylene Sheet for Tanks, Trays & Fabricated Parts
Natural copolymer polypropylene is a thermoplastic material designed for applications requiring a balance of impact strength, flexibility, and chemical resistance. This grade offers improved flexibility and low-temperature impact strength compared to standard homopolymer polypropylene through the use of an ethylene comonomer in the manufacturing process.
This rugged, lightweight material absorbs very little moisture and provides dependable toughness for fabricated tanks, trays, covers, guards, and containment components. It sees use in applications that require reliable fatigue resistance and are continuously exposed to many chemical solvents, bases, and acids.
Looking for a more rigid option? For applications where stiffness is a higher priority than low-temperature flexibility, consider our Homopolymer Polypropylene.
Why Choose This Specific Sheet?
Natural Copolymer Polypropylene provides a dependable blend of toughness and formability. It is the correct choice if you need:
Enhanced Flexibility:
The ethylene comonomer increases flexibility and toughness compared with homopolymer polypropylene, making this sheet suitable for formed parts, covers, and dynamic components where impact resistance is important.
Improved Impact Strength:
Offers better energy absorption and impact resistance, especially in low-temperature environments.
Chemical Resistance:
Resists many acids, bases, solvents, and other industrial chemicals.
Stress Crack Resistance:
Designed to reduce the risk of environmental stress cracking under load.
Low Water Absorption:
Absorbs very little moisture, helping fabricated components maintain consistent performance in wet and humid environments.
Copolymer vs. Homopolymer Polypropylene: Which Do You Need?
While both are polypropylene-based plastics, they are formulated for slightly different mechanical requirements.
Choose Copolymer PP (This Sheet) if enhanced flexibility, toughness, and low-temperature impact strength are your priorities. It is a good choice for parts exposed to impact, flexing, or cold-service conditions.
Choose Homopolymer PP if structural rigidity and higher tensile strength are required, and low-temperature impact is not a primary concern.
Fabrication & Thermoforming

PRONEQ SH
Technical Performance
Natural copolymer polypropylene is engineered for applications requiring a practical balance of chemical resistance, low moisture absorption, and reliable impact strength, particularly in low-temperature settings.
Cold-Service Components: Parts requiring better impact toughness at reduced temperatures than homopolymer polypropylene typically provides.
Formed Components: Thermoformed liners, housings, protective covers, and other parts that benefit from toughness and formability.
Engineering Limitations & Alternatives
While copolymer polypropylene is highly versatile, specific mechanical or environmental demands may require different material selections:
Structural Rigidity: Copolymer polypropylene sacrifices some stiffness to achieve its flexibility and impact strength. Better Alternative: For structural applications requiring greater rigidity, choose Homopolymer Polypropylene.
Extreme Continuous Heat: While formable at elevated temperatures, standard copolymer polypropylene is not recommended for continuous load-bearing use in extreme heat. Better Alternative: For high-heat applications, consider materials like PEEK.
Machining Tolerances: Like many softer, flexible thermoplastics, holding extremely tight precision tolerances can be difficult. Better Alternative: For precision machined components that require tight tolerances, consider Acetal.
