Vulcanized Fibre is a hard, durable, chemically pure cellulose product that contains no resin or bonding agents. It offers flexibility, impact resistance, high tear strength and a smooth, abrasion resistant surface.

Vulcanized Fibre can be used for washers, insulating plates, switch and appliance insulation, electric motor insulation, gaskets, automobile parts, luggage, patterns, and many other applications. Its properties include:
- High Mechanical Strength
- Excellent Resistance to Heat and Cold, superior to most plastics
- Light Weight, Half the weight of Aluminum

Per Wikipedia and my personal use of the stuff. . .
Forbon is a vulcanized fiber that was created in the early 1900s by the NVF company. It was used on the original pickups that Leo Fender (founder of Fender Guitars) created for the Stratocaster, Telecaster, and the Precision Bass. It is still used on reissue guitar and bass models from that era.
