The invention relates to a wood substitute material for wood-encased pencils, comprising the following ingredients: 15% - 30% by weight of at least one polymeric binder, 50% - 80% by weight of at least one organic filler, 0% - 20% by weight of at least one inorganic filler, 0.5% - 5% by weight of at least one adhesion promoter, 1% - 30% by weight of at least one wax, 0% - 10% by weight of at least one colour pigment, and 0% - 10% by weight of at least one additive, the at least one adhesion promoter forming a chemical bond between the at least one polymeric binder and the at least one organic filler, a ratio of the at least one adhesion promoter to the at least one wax in the range from 1:2 to 1:6 being formed, and the sum of organic and inorganic filler being not more than 80% by weight. |
