A unique ivory substitute in a polyurethane matrix - ethical, sustainable and perfected for discerning craftsmanship worldwide.
elforyn® is a high-performance polyurethane-based plastic formulated by BKT Germany that replaces real ivory with a deceptively authentic look, feel and machinability. The material contains a UV dye for clear identification versus genuine ivory under black light - species protection can be this simple.
Declarations of compliance are available for elforyn® and JUMA® for direct contact with mouth and skin. Through our online shop elforyn.de, four elforyn® variants and six JUMA® design lines are available in numerous formats - from round bars and square profiles to plates and blocks.
