Welding Protection (Small Molten Metal Splash): Meets ISO (No NA Standards Developed Yet)

Predicted Body Burn: Consistent Protection Against Unpredictable Fires Actual Garment Weight

Permanent: Inherent Protection is Permanent Per NFPA 2112 Requirement

Drying Rate: Nomex ® MHP Dries 33% Faster than FRTC, Keeping Wearers Comfortable

Weight: Actual Measured Weight more than 0.05 oz/sy lighter than competition

Comfort Nomex ® MHP is the overall winner on key comfort criteria while keeping the Nomex ® and Kevlar ® strength Goal: Qualify & quantify the consumer perceptions via a trained panel (sample of the population) Describe the products and perceptions with minimum words & a maximum of information Sensory method base on ISO13299 & ISO11035 IFTH (French Textile & Clothing Institute) – Cutting edge technology to develop and prove comfort vs. other fabrics Best scores for: Softness: “pleasant sensation to the touch” Smooth: “low perception of harshness” Thinnest: “low height of the samples perceived between fingers” Most drape: “it evaluates the falling of the material under its own weight” Least stiff: “capacity of the fabric to slide between fingers without resistance” Least voluminous: “perceived quantity of residual material after squeezing it on the hand” Crease recovery: “capacity of the fabric to recover its initial shape” Least nosy: “hearing perception resulting from the friction of the material with itself”

IFTH Comfort Study Results Based on this independent study, Nomex ® MHP is the clear winner in the comfort characteristics tested

compared to FR treated cotton Superior Durability (*from high aramid content) Overall, Nomex ® MHP will provide better durability than its competitors Break strength + Abrasion Resistance = Predicted Durability Predictions of long term durability come from the combination of performance in both abrasion and break strength after laundering. Nomex ® MHP abrasion actually improves with laundering and has great break strength. Nomex ® MHP break strength 60% higher than FR Treated Cotton The high aramid content of Nomex ® MHP provides superior abrasion resistance

Superior Professional Appearance and Longer Service Life DuPont is currently testing industrial laundering MHP fabrics/ garments and competitive fabrics. We will provide photos of garment performance and washed down fabric swatches, including competitive fabrics, to help sell with end users.
