Vulcanized Fibre, Commercial Grade, is a hard, durable, chemically pure cellulose product that contains no resin or bonding agents. Vulcanized Fibre is manufactured in Rolls, Coils, Sheets, Tubes and Rods. The commercial grade of Vulcanized Fibre is sometimes referred to as "Fibre". 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
  • Excellent Electrical Properties
  • Good Arc Resistance
  • Excellent Tear Resistance
  • Can be Machined with Standard Tools
  • Available in Rolls and Coils for easy automatic punching

    UL File No.: E55656 Material Designation HB-77
    ASTM Spec: ASTM D-710, Commercial
    Military Spec: Mil-F-1148, C-H; Mil-F-I 3526, Red Sheet
    NEMA Grade: Vulcanized Fibre, Commercial

    High mechanical & dielectric strength. Good shock absorting & wear resisting qualities. Excellent punching, forming, & turning characteristics. Semi-hard & has a good surface finish.

    *20.00 small line charge applies to each line item less than 200#'s and up to each 50# parcel/carton.
