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.
