DuPont and LION Collaborate on PPE Materials

WILMINGTON, DE and DAYTON, OH—DuPont and LION have collaborated on a new offering for firefighters and first responders: PPE that protects, from the inside-out with the most advanced blends of DuPont™ Kevlar® filament and DuPont™ Nomex® and Kevlar® staple.  LION was the first company to adopt new Kevlar® products in blends with Nomex® to provide maximum protection.

LION’s Janesville® V-Force® garments with new Kevlar filament-based outer shells and thermal liners offer game-changing comfort and strength, using Kevlar and Nomex for added comfort, mobility and durability. Coupled with DuPont materials, LION’s design for its V-Force turnout gear’s tailored cut differs significantly from other available models and provides a unique fit for better mobility, less physiological burden, and enhanced ruggedness.

Every layer of LION’s firefighter protective apparel includes Kevlar and Nomex, either alone or in blends.  They are critical materials in three key layers: an outer shell with cut and flame  resistance, a moisture barrier that prevents penetration of liquid and blood-borne pathogens, and a thermal liner that provides efficient thermal insulation while not restricting user mobility.

DuPont and LION collaborate with fire departments around the world to test new fiber technologies and thermal protection within firefighter gear.  DuPont Nomex can withstand temperatures up to 700 degrees Fahrenheit. Nomex® and Kevlar® are inherently fire-resistant and do not need to be treated. Tested through DuPont’s Thermo-Man® unit, they are both self-extinguishing and durable.

DuPont sees the industry migrating to increased blends of Kevlar and Nomex.  In addition to Nomex, which is best known for its fire protection, there is growing interest in Kevlar for its cut resistance and increased strength. Kevlar adds toughness and durability to the garments, providing more protection from the harsh environments firefighters and first responders face. Nomex provides better comfort and day-to-day wearability.
