For the production of pencil and coloured crayon Celopro® is used as a binder and plasticiser. The lead of the crayon achieves a higher flexibility and a higher braking strength due to the use of Celopro®. A further advantage is the high compatibility of Celopro® in combination with all other raw materials used.
We recommend Celopro® H and MC (MHEC/HPMC) grades with a low to medium viscosity level.
