Vulcanized Fibre

What is Vulcanized Fibre?

One of the first plastics ever developed, vulcanized fibre is a tough, resilient compound that makes an excellent material choice for washers and gaskets in many applications. Comprised of wood pulp, paper, and rag material, vulcanized fibre outperforms many standard materials with its light, stiff, and tough qualities.

Vulcanized fibre is almost 100 % cellulose, and completely free of artificial additives like resin, binders, or glues. The material can be used to provide electrical insulation, strengthen wood laminations, surface drum cases and skid panels, manufacture automobile components, and much more. Base commercial grade fibre is available in grey, black, red, and white; NPF also provides other grades and colors upon request.

Benefits and Performance

Light and highly machinable, vulcanized fibre offers a long list of material benefits, including:

Good impact and abrasion resistance
High tensile and tear strength
Excellent electrical performance
Superior, smooth bending
Easy machinability to punch, saw, shear, mill, and drill
Great arc and track resistance
U.L. 94HB flammability rating
Insolubility in ordinary solvents and imperviousness to most oils and petroleum derivatives, as well as alcohol, ammonia, benzene, and more

Applications

Because it can be easily manipulated through forming, molding, slitting, machining, or punching, vulcanized fibre can be used in an incredibly diverse number of ways, including - but certainly not limited to - the examples outlined below:

Washers, gaskets and custom tags
Automotive components
Electronics and electrical insulation
Plumbing and marine components
Furniture manufacturing
Home and garden maintenance
Aerospace and military equipment
Farming tools
Guitar bobbins

Standard Grades

Vulcanized fibre is available in five standard grades. The newest and most innovative, wood laminating, was developed specifically for low-glue pressed wood projects such as support beams, skis, and custom veneers.

Commercial Grade; for gaskets, washers, handles, gears, and similar components
Electrical Grade; 100 % cotton for layering and ground insulation in motors and tools
Trunk Fibre; durable and hard for skid panels, drum cases, and high wear applications
Bone Fibre; with exceptional hardness for tight machining, cut out fuses, pool cue tips, and more
Wood Laminating; for stabilizing and strengthening thin veneers and adding toughness and tensile strength to laminations in skate decks, paneling, etc.
