日興エボナイト製造所 Company Profile

It is the only ebonite factory in the country. It is made from natural rubber raw materials and is used not only as an insulating material but also as a material for fountain pens, musical instruments, and smoking accessories.

Ebonite, said to be the world's oldest resin. Hard rubber ebonite, made from natural rubber, has been used for a long time in fountain pens and mouthpieces for woodwind instruments. Ebonite rods, sheets, and tubes have high insulation properties, oil resistance, water resistance, chemical resistance, and low thermal conductivity. We also accept molding processing. Oil-resistant NBR floats have a smooth and hard surface with independent foam membranes inside. We also offer metal and magnet insert molding. "Our desire is to make ebonite a widely loved material." "Our desire is to preserve Japan's proud lathe technology for future generations." To pass on the technique of "lathe turning," which is fading without being handed down, Nikkō Ebonite Manufacturing started making fountain pens.
