Color compounds for the production of crayons from GRAFE

Traditional crayons are often brittle and break easily or achieve only patchy coverage. The new color compounds from the GRAFE Group make it possible to produce injection-molded crayons, which wear down less quickly, achieve a more even coverage and are especially resistant to breakage. The new development has also led to a low-distortion crystallization of the materials, so that even large geometries can be injection-molded without any stress cracks. In addition, the crayons guarantee smudge-free coloring for keeping little and big hands clean.

„Because little children often put crayons in their mouths we have taken special care during the development of the wax compounds, to ensure that all pigments and other ingredients are harmless“, explains Dr. Jan Stadermann, leader of the project. „Approvals in accordance with toy standard DIN EN 71-3 are therefore in principle possible.“ Our color range consists at the moment of six main and six additional colors. Further colors may be added upon customer request.
