For Industrial Filter Applications 
       Comfortable, lightweight and thin filters for P100 dust masks.


TEMISH™ porous PTFE(polytetrafluoroethylene) has been developed with unique processing technology patented by NITTO DENKO. TEMISH has high air permeability due to millions of micropores per square centimeter. It has many excellent features such as Chemical-resistance,Heat-resistance,Water-resistance,High particle removal,Weatherabillity,Electric-Insulation,etc.


  • Selective permeability allows air to pass through while repelling water. 
  • Has various properties such as chemical resistance and heat resistance. 
  • Can be laminated or compounded with various base materials.
