Vulcanized fibre
Vulcanized fibre is made by combining layers of chemically gelled paper of pure cotton celuloise.
The chemical compound (ZnCI ) used in gelling the paper is subsequently removed by leaching, and the résulting product, after being dried and finished by calendaring, is a dense material and a chemically pure product. lt is made in four primary forms: sheets, rolls, coils and tubes.
Strong and light industrial material, and has high impact resistance. Good dielectric strength and high are resistance.
Can be formed, punched and machined.
