Vulcanized fiber

€0,00

Vulkanfiber is a versatile material made from a special paper made from cotton linters and cellulose. Produced on the basis of organic renewable raw materials, Vulkanfiber is characterized by the following properties:

 

  • High mechanical strength with low weight
  • Good antistatic properties
  • Good electrical insulation properties (spark-quenching)

 

Heat class Y (95 °C) Roll material from 0.2 – 2 mm sheets, homogeneous from 0.5 – 2 mm sheets, layered from 5 – 100 mm
