Vulcanlized fiber sheet is a hard working paper.Finished products are flat, reel, tube and so on.Paper is hard.Excellent elasticity, wear resistance, corrosion resistance, heat resistance, mechanical strength, insulation and mechanical processing and molding properties.
Vulcanized fibre is a laminated plastic composed of only cellulose. Vulcanized fibre is a tough, resilient, it is lighter than aluminium, tougher than leather, and stiffer than most thermoplastics.
Features
Good insulation
Flexibility
Water resistant
Wear--resisting
Grease, ageing resistance
Good blocking gap material.
Applications
Widely used for small motor and electrical insulation slot liner, gasket and turn to turn and layer insulation, liner insulation, transformer insulation, and other electrical insulation with temperatures requirement not exceeding 120 C.
