Vulcanized fiber is a laminated plastic material made from cellulose layers. These sheets and tubes offer excellent electrical insulation, mechanical strength, and machinability.

Its hardness and strength are analogous to aluminum, but with a half weight of aluminum in specific gravity only. It has very good mechanic processing property. No delamination or splitting during the process of cutting, drilling, milling and stamping. It has good oil resistance, incombustibility, arc extinction and insulation properties. It’s an ideal material for aviation, electric power and transmission line, textile, electric, railway and other related industries.
