  • Pencils and Methods for Their Production
    Publication number: 20070223985
    Abstract: Pencils having a core within a barrel, the barrel being formed from a blend of at least two transparent polymers which are incompatible and form separate phases within the blend, the polymers having refractive indices which differ by not more than 0.02 when measured under substantially the same conditions. Blends for use in producing the barrels of such pencils have shown good sharpenability combined with high transparency. The latter enables the core of the pencils to be clearly visible through their barrels.
