  • Fire extinguishers: CO2, extinguishing foam, water
  • Harmful decay byproducts: none
  • Things to avoid: none
  • Handling and storing safety precaution: none
  • Lower calorific value: 21600 Kj/Kg
  • Specific heat: 0.24 Kj/Kg°K
  • Steam permeability: µ = 3.11
  • Certified by the Home Ministry
  • 100% recyclable as they do not contain additives or binders other than polyester
