Vulcanized fibre is a laminated plastic composed of only cellulose. The material is a tough, resilient, hornlike material that is lighter than aluminium, tougher than leather, and stiffer than most thermoplastics. The newer wood-laminating grade of vulcanized fibre is used to strengthen wood laminations used in skis, skateboards, support beams and as a sub-laminate under thin wood veneers.
The final product is a homogeneous nearly 100%-cellulose mass free from any artificial glues, resins, or binders. The finished vulcanized fibre has useful mechanical and electrical properties. It offers high tear and tensile strength, while in the thinner thicknesses allowing flexibility to conform to curves and bends. In thicker thicknesses, it can be moulded to shape with steam and pressure. One application for vulcanized fibre that attests to its physical strength is that it is the preferred material for heavy sanding discs. The electrical properties exhibited by vulcanized fibre are high insulating value, and arc and track resistance with service temperature of up to 110 to 120°C. Vulcanized fibre shows high resistance to penetration by most organic solvents, oils, and petroleum derivatives
Commercial Grade; standard grey, black or red, used for many applications such as washers, gaskets, gears, handles, etc.
Electrical Grade: high dielectric grey, 100% cotton, very flexible, (historically called fishpaper), this grade is suitable for layer and ground insulation and has variations including top-stick grade used for wedges in small motors.
Trunk Fibre: Tough and abrasion resistant; used to surface steamer trunks, drum cases, wear and skid panels.
Bone Fibre: Exceptionally hard and dense, used for tight machining, tubing, pool cue ferrules (tips), cut out fuses.
Wood Laminating: Tough, multi-directional tensile and torsion strength, provides support and strength wherever wood laminations are used, particularly used under thin and exotic veneers as a stabilizer/strengthener.
