Cut-to-Size orders are currently taking 2 to 3 days (Monday-Friday) to process
Cut to size orders are cut with table and CNC panel saws and have a cut tolerance of +/- 1/32". Plastic sheets have a thickness tolerance of +/- 10% and can have thickness variations throughout the sheet. Cut to size items cannot be returned for a refund or exchange.
Sheet sizes, colors, thicknesses and products available on our website are available at TAP Plastics stores.
Visit or contact your local TAP Plastics store where cut-to-size orders often take less than five minutes, start to finish.
King ColorCore® is a multi-layer, high-density polyethylene (HDPE) sheet designed for premium outdoor signage, labels, displays, and recreational applications. Made in the USA using King Plastic's proprietary PolyFusion™ process, these homogeneous sheets feature a contrasting cap and core color ideal for CNC engraving. Unlike laminated or printed surfaces, the color layers run throughout, ensuring long-lasting readability without the risk of delamination, rust, or rot.
Key Features & Benefits:
-
Engravable Cap Layer: Cap thickness typically .050" (check depth before cutting). CNC users often cut 0.075" to reveal the core color with clarity.
-
CNC Optimized: Engraves cleanly with 30° or 60° v-bits for a crisp carved effect. Use sharp solid carbide bits (double o-flute or down-spiral) for best results.
-
Speed Recommendations:
-
V-bits: 20,000 RPM at 150 IPM, 0.1" depth/pass
-
1/8" bits: 16,000 RPM at 80 IPM
-
1/16" bits: 15,000 RPM at 60 IPM
Always test settings with your CNC machine for optimal performance.
-
-
Durability: Resists impact, water, UV, and harsh weather. Ideal for marine, park, and playground signage.
-
No Painting or Refinishing Needed: ColorCore® retains its vibrant color and matte texture without coatings.
-
Chemically Resistant: Most household and commercial chemicals, including cleaners, will not harm the surface.
Common Applications:
-
Outdoor engraved signs and plaques
-
Legend plates and switch labels
-
Playground equipment and recreational panels
-
Boat dashboards and marine labeling
-
Carnival and amusement signage
-
Architectural signage and directional panels
-
Durable point-of-sale and museum displays
Maintenance & Cleaning Tips:
-
Everyday Cleaning: Use Soft Scrub® and a nylon brush. Avoid excessive force to preserve the matte finish.
-
Stubborn Stains: Try Goof Off®, Mr. Clean Magic Eraser®, or citrus-based degreasers. For petroleum-based marks, use mineral spirits, WD-40®, or acetone with a white nylon pad.
-
Avoid: Teak oils, magic markers, and uncoated metal contact, which may stain light colors. Do not use MEK or turpentine.
-
Temperature Limit: Do not expose to constant temps above 180°F.
-
Pro Tip: Light media blasting (e.g., Zendex Speed Blaster with glass beads) can reduce tool marks without damaging the texture.
Fabrication Notes:
-
Cut with standard woodworking tools (carbide blades recommended).
-
Not glueable with traditional adhesives—use stainless steel fasteners.
-
Allow for thermal expansion: 1/32" per 40°F shift.
Finish Options & Colors:
Standard colors are matched to coordinate with King ColorBoard® for projects that require consistent design language across materials.
