FireGuard is a high-tech p-aramide surface finish. It increases the resistance of the needle felt to flying sparks. FireGuard also offers excellent resistance to abrasion and mechanical wear. 

  • Protection from flying sparks 
  • Thermally resistant even at high contact temperatures 
  • Extended operational life


     

 

Areas of application: e.g. in the metalworking industry and in the non-ferrous metal industry
