Sipario Bionylon® Strings: Eco-Friendly Bio-Polymer Technology for Harps
Sipario Bionylon® strings represent an advanced generation of eco-friendly synthetic harp strings developed in collaboration with Aquila Corde's acoustic research lab. Made from a specialized bio-plastic derived 63% from plant derivatives (castor oil), Bionylon® delivers superior acoustic projection while reducing carbon emissions by over 50% during polymer synthesis compared to standard nylon.
