Vulcanised fibres

Product description

The vulcanized fiber is obtained by laminating 100% cellulose paper plies after passing through zinc chloride and acid baths. This manufacturing process gives this insulator high mechanical, insulating and electrical characteristics.

ADDEV Materials transforms vulcanized electrical and mechanical fibers for the electro-technical, railway and industrial sectors – several grades are available depending on the final use of the product. The vulcanized fiber can also be cut to size to obtain a specific insulation.

Technical properties

  • Continuous use temperature 120°C
  • Fire classification (UL94 HB or VO depending on grade)
  • Very good dielectric strength (good arc resistance)
  • Excellent resistance to chemical products
  • Excellent mechanical resistance (abrasion, tear propagation, etc.)
  • Impregnable
