Boot Liners And Insoles

NSI Materials Group offers liners that are made for maximum comfort, foot hygiene, and extreme weather conditions. These liners are made with eco-friendly wool and synthetic felt that adds warmth and cushioning to your feet. In addition some models use Cambrelle™ and Radiantex™ for durability, insulation, and moisture management. Most models are reinforced with a Naugahyde backing for extra protection against wear and tear. NSI Materials Group Insoles protect from the effects of cold and moisture while providing an atmosphere of comfort. Crafted from breathable wool felt and cold-deflecting layers like Radiantex™, our Insoles manage temperature and moisture levels. In addition, the wool content enables the insole to absorb three times its own weight of moisture and release it when ventilated.

Precursor Carbon Felt

Polyacrylonitrile fibers (PAN) will not burn, melt, soften, or drip. PAN fibers are extremely heat and flame resistant (up to 1800˚F), with low thermal conductivity. PAN fibers also have high electrical resistance and mechanical strength.


Aramid Needle Punched Felts

Aramid needle punched felts come in two classes: meta-aramid and pera- aramid. Aramid is a man-made high-performance fiber, with molecules characterized by relatively rigid polymer chains. These molecules are linked by strong hydrogen bonds that transfer mechanical stress very efficiently, making it possible to use chains of relatively low molecular weight. Aramid fibers share some general characteristics that distinguish them from other synthetic fibers:
  • High Strength
  • Good resistance to organic solvents
  • Non-conductive
  • No melting point
  • Low flammability
  • Good fabric integrity at elevated temperatures

Meta Aramid

Meta-aramid fibers do not ignite, melt, or drip. They retain their mechanical properties at elevated temperatures. Even though meta-aramid fibers have higher tensile strength and lower thermal conductivity than many FR fibers, they are soft to handle and processes similarly to conventional fibers.
