Long-Term Outdoor Signage Solutions with HDPE ColorCore© – Precision Plastics

Long-Term Outdoor Signage Solutions with HDPE ColorCore©

ColorCore© high density polyethylene (HDPE), also known as “sandwich board” is a versatile, environmentally stabilized sheet with multiple layers of contrasting colors. Its thin cap layers and bright primary colors make it ideal for signage, marine, playground and recreational applications. ColorCore© HDPE sheets come in different sizes, thicknesses and color combinations to meet your needs.

Features of ColorCore©

ColorCore© is a high-impact-resistant polymer to handle more abuse than conventional sign materials. It is stress and crack resistant and will not warp, rot or delaminate.  ColorCore© is easy to machine with common woodworking tools and techniques and can also be machined using laser cutters and CNC routers to reach maximum precision. The base materials are FDA approved and provide long-term outdoor signage and wayfinding solutions.


ColorCore© is homogeneous sheet, made with a unique state-of-the-art continuous process, manufactured to the highest standards in the industry. When engraved by laser or standard woodworking tools, the inner core color is revealed. No further printing or lamination is required, allowing markers and spray paint to be easily removed and making ColorCore© popular for high traffic outdoor areas such as playgrounds, pools, warning signs, and corporate signage. Other common uses include architectural applications, carnival games, children’s furniture, marine applications, museums, picnic tables, point-of-purchase displays, and wayfinding signage.

Our design and fabrication teams can assist you with finishing styles, mounting and posting. Let Precision Plastics help you design and manufacture the perfect product using ColorCore©.
