Hydrophilic Rubber profile

 

  • Hydrophilic rubber profile, available in different dimensions, is used for sealing applications in civil engineering and tunneling.
  • The swelling ability happens due to hydrophilic resins which can expand in contact with water.
  • Color: red, black (other colors available upon request)
