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).

HDPE Black Sheet
Black Industrial Grade HDPE | Cut-to-Size & Full Sheet | Impact, Moisture & Chemical Resistant
Industrial Black HDPE for Impact, Moisture & Chemical Resistance
Black HDPE is a durable engineering plastic commonly used in industrial, fabrication, and utility applications. Compared to Natural HDPE, the opaque black color helps conceal dirt, grease, oil, and handling marks in demanding work environments.
It offers strong impact resistance, low moisture absorption, and broad chemical resistance, making it well-suited for wear liners, fabricated trays, machine guards, spacers, equipment components, and general-purpose industrial parts.
Note on Surface Finish: This is an unmasked, industrial-grade plastic sheet. Minor scuffs and handling marks are normal and do not affect material performance. If you require a pristine, textured cosmetic finish for visible boat cabinetry or finished marine components, we recommend King StarBoard®.
Why Choose Black HDPE?
This sheet is a practical choice for demanding industrial, fabrication, and utility applications. It is the correct choice if your project requires:
Impact Resistance: HDPE absorbs impact well and resists cracking or shattering in many fabricated parts, guards, liners, and handling components.
Aesthetic Maintenance: The opaque black color helps hide grease, oil, dirt, and handling marks. This is useful in factory, maintenance, and equipment environments where lighter-colored sheets can show stains quickly.
Broad Chemical Resistance: Resists many acids, alkalis, solvents, and detergents, depending on concentration, temperature, and exposure time. Its non-porous surface also helps reduce moisture absorption and odor retention.
Thermoforming: Unlike UHMW, HDPE can be heated and vacuum-formed. This makes it useful for manufacturing complex 3D shapes like automotive dunnage, custom trays, and equipment housings.
Material Selection: Which Polyethylene Do You Need?
Polyethylenes look similar but perform differently. Choose the right grade for your application:
Choose Black HDPE (This Sheet) for industrial, fabrication, or dirty work environments. Black HDPE is a strong choice for liners, trays, guards, spacers, fabricated parts, and applications where a dark, grime-hiding material is preferred.
Choose Natural (White) HDPE for sanitary or food-contact environments where FDA compliance is required. Best for cutting boards, food chutes, and food-processing components. Confirm compliance before use in regulated food-contact applications.
Choose Pipe Grade HDPE for applications that require higher-density HDPE sheet with improved stiffness, strength, UV resistance, and durability for fabricated parts, tank components, liners, and industrial equipment applications.
Choose UHMW for sliding wear. If you need extreme abrasion resistance, a lower coefficient of friction, or longer wear life in conveyor guides, chute liners, or snow plow edges, UHMW is usually the better choice.
HDPE is non-abrasive and easy to machine using common woodworking tools. It can be cut with standard carbide-tipped saw blades and drilled with standard bits. Due to its low surface energy and chemical resistance, HDPE is difficult to bond with standard adhesives or solvent cements. It is typically mechanically fastened, heat-welded, or bonded only with specialty adhesive systems designed for polyethylene.
