Ply markers and crayons have zero VOCs and are typically used to mark rubber surfaces for inspection and identification.

Ply markers, also known as fugitive crayons, are a valuable tool for marking uncured rubber surfaces such as calendered material, plies, and bead rings. The product does not act as a contaminant and will not cause delamination. Ply markers are available in standard, jumbo and triangular sizes and can be applied manually or by machine.

Crayons, also known as non-fugitive markers, are a valuable tool for marking cured (external) rubber surfaces. Available in a variety of colors, crayons are available in standard, jumbo and triangular sizes.

Ply markers and crayons are sold by the gross and packaged with 72 crayons per box. Products may be purchased labeled or unlabeled.

Other Uses and Applications:
Crayons can also be used for other unique applications including those that require marking on wet or dry surfaces as well as glass.

*The shelf life of ply markers or crayons relies almost entirely upon the proper storage of the stock. These identification markers are highly perishable when stored at temperature extremes. If stored in a cool, dry, area between 10-24°C, (50-75°F) the shelf life can be extended up to 5 years.
