• Large Stock of pressed cardboard sheets BELPA CSA-90 direct from the factory, consult formats and thicknesses.
  • The pressed cardboard sheet Belpa CSA 90 is made with aramid fibers and mineral fibers of high quality mixed in a matrix of NBR rubber.
  • A compressed cardboard board for joints is achieved with:
    • High resistance to compression
    • Good resistance to traction
    • Very low permeability to gas
  • Excellent characteristics for most industrial services especially in the chemical and petrochemical industry where the high demand for resistance to temperature and pressure must be combined.
  • This pressed cardboard is a material with excellent resistance to oils , hydrocarbons , alkalis and steam to moderate pressures.
  • We also have plates with metallic reinforcement and non-stick surface finish on both sides with ref. CSA-90 MG
