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.
Tough & Flexible Black Copolymer Polypropylene Sheet
Black copolymer polypropylene is a lightweight thermoplastic sheet designed for applications requiring a practical balance of impact strength, flexibility, and chemical resistance. The addition of an ethylene comonomer improves flexibility and low-temperature impact performance compared to standard homopolymer polypropylene.
Its opaque black appearance works well for industrial components where a dark, uniform color is preferred. This material also features very low moisture absorption and dependable resistance to many solvents, bases, and acids, making it useful for containment, protective components, packaging, and fabricated parts exposed to moisture or chemicals.
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?
Black copolymer polypropylene provides a useful combination of toughness, formability, and chemical resistance. It is the right choice when you need:
Opaque Black Appearance:
Provides a consistent dark color for fabricated industrial parts, equipment components, protective panels, and applications where visual contrast or color coordination is important.
Enhanced Flexibility:
Copolymer polypropylene offers greater flexibility than homopolymer polypropylene, making the sheet suitable for formed parts, covers, and components exposed to flexing or impact.
Improved Impact Strength:
Absorbs impact energy more effectively than standard homopolymer grades, particularly in lower-temperature environments.
Chemical Resistance:
Resists many acids, bases, and chemical solutions commonly encountered in industrial applications.
Low Moisture Absorption:
Absorbs very little water, supporting dimensional stability and moisture-resistant performance in wet or humid environments.
Tougher Copolymer Formulation:
Provides improved impact resistance and flexibility compared to homopolymer polypropylene.
Copolymer vs. Homopolymer Polypropylene: Which Do You Need?
Although both materials are polypropylene-based, they are formulated for different mechanical requirements.
Choose Copolymer PP (This Sheet) when flexibility, toughness, and low-temperature impact strength are priorities. Copolymer polypropylene is commonly used for parts exposed to impact, repeated handling, flexing, or cold-service conditions.
Choose Homopolymer PP when greater structural rigidity and tensile strength are required, and low-temperature impact performance is not a primary concern.
Fabrication & Thermoforming
This material combines moderate rigidity with good formability and can be fabricated or thermoformed into a range of industrial and commercial components. Black sheet may respond to radiant heat differently than natural sheet; processing trials are recommended to establish appropriate forming conditions.

PROBEQ SH
Technical Performance
Black copolymer polypropylene is engineered for applications requiring a practical balance of chemical resistance, low moisture absorption, flexibility, and dependable impact performance, including components used in lower-temperature environments.
Black sheet may respond differently to radiant heating than natural sheet, so heating time and temperature should be confirmed through processing trials. Note: Standard industrial grades are not recommended for continuous load-bearing use in high-heat applications.
Chemical Resilience:
Resists many acids, bases, and chemical solutions, making it suitable for fabricated components exposed to a range of industrial chemicals.
Flex Fatigue Resistance:
Features dependable flex-fatigue performance and toughness for parts exposed to repeated flexing, handling, or impact.
Key Properties
Opaque Black Color:
Consistent dark appearance works well for industrial components, equipment parts, protective panels, and applications requiring visual contrast or color coordination.
Low-Temperature Toughness:
Retains impact resistance more effectively than homopolymer polypropylene in lower-temperature conditions.
Moisture Resistance:
Features very low moisture absorption and maintains its properties in many wet or humid environments.
Impact & Flexibility Balance:
Its tougher, more flexible formulation improves impact performance and flexibility compared with more rigid polypropylene grades.
Mechanical Strength:
Its strength-to-weight ratio is useful for rugged components where low material weight is beneficial.
Common Industrial Applications
Fluid Handling & Containment: Chemical tank components, fluid transfer parts, reclaimed water systems, secondary containment linings, and moisture-resistant barriers.
While black copolymer polypropylene is suitable for many fabricated components, certain structural or environmental requirements may call for a different material or grade:
Structural Rigidity: Copolymer polypropylene gives up some stiffness in exchange for greater flexibility and impact strength. Better Alternative: For structural applications requiring greater rigidity, choose Homopolymer Polypropylene.
Elevated-Temperature Service: Standard copolymer polypropylene has a typical continuous operating temperature of about 180°F, and strength and stiffness decline as temperature rises. Better Alternative: For applications requiring higher-temperature service, consider materials such as PTFE (Teflon®).
Machining Tolerances: Like many softer, flexible thermoplastics, copolymer polypropylene can be difficult to machine to extremely tight tolerances. Better Alternative: For precision-machined components where dimensional stability and tight tolerances are critical, consider Acetal.
Outdoor Exposure: Though it is black in color, this material is not necessarily suited for long-term outdoor applications. Better Alternative: For long-term outdoor applications, consider a material like Pipe Grade HDPE.
