Dupont opens a testing lab for Kevlar in India to run ballistics and stab resistance

I read today about Dupont opening a testing facility in Hyderabad at about 700 kms east of Mumbai. I am not sure this is really hot stuff or i missed the info already old for few of my readers…anyway…

The testing house is said to be dedicated to ballistics and stab resistant materials…they also declare having a press of aprox. 600 tons for ballistic protective helmets.

With this new opening Dupont counts now with 5 testing facilities. The other 4 are based in Switzerland, Brazil, USA (2 in the US, one in Richmond VA and the other one in Wilmington_Delaware).

Sounds like the Indian Market is the key hot market for the US company and the objective with no doubt is to educate final users and direct customers on kevlar properties and make sure they know how to transform their product. Liability is extremely important for the fiber company so having a private own lab will help a lot small helmet and body armor producers to design their solutions as long as they use Kevlar, of course…

¿Qué es el Kevlar?

¿Qué es el Kevlar?

El Kevlar es una poliamida sintetizada por Stephanie Kwolek, una química de la firma DuPont, en 1965. Sus fibras consisten en largas cadenas de poliparafenileno tereftalamida, molécula que soporta altas temperaturas con la que se puede construir equipos ligerosresistentes –5 veces más fuerte que el acero– y a los que no les afecta la corrosión. Actualmente se utiliza para reforzar prendas textiles de montaña por su gran capacidad y resistencia, como por ejemplo en los hombros de las chaquetas para evitar su desgaste por el rozamiento con la mochila.

Defense Review – DuPont Kevlar XP: Next-Gen, Lightweight Aramid Ballistic Fiber for Body Armor

DuPont Kevlar XP: Next-Gen, Lightweight Aramid Ballistic Fiber for Body Armor

Body Armor By David Crane

15% less backface deformation signature (BDS), and thus reduced impact trauma a.k.a. blunt force trauma, with 10% reduction in overall (OA) weight, all in a 100% Kevlar, i.e. woven, high-strength ballistic aramid fiber, solution–this is the promise of DuPont Kevlar® XP™ woven ballistic aramid fiber for military and law enforcement (LE)/police body armor and other ballistic armor products (i.e. vehicle armor, aircraft armor, etc.) in the near future. Mark McGonagle, Global Marketing Manager for DuPont Personal Protection, describes Kevlar XP as a \”patented, next-generation woven fiber technology that enables more comfortable, more flexible, lighter-weight ballistic vests made with Kevlar fiber.\”

From what DefenseReview understands at present, the key to the improved performance of Kevlar XP is

a combination of new weaving and coating processes that are applied to an existing Kevlar product (unconfirmed/unverified). If this is the case, we\’re curious as to which existing Kevlar product is utilized. Perhaps Kevlar KM2 or Kevlar 129? We\’ll try to find out. We\’ll also try to glean more about the coating material(s) and process(es).

Kevlar XP can apparently consitently stop a .44 Magnum bullet in the first 2-3 layers of an 11-layer ballistic panel/vest. \”The bottom line is that it stops bullets faster,\” said Dale Outhous (yes, that\’s his real name), global business director for DuPont Personal Protection. Defense Review will try to find out if a Kevlar XP ballistic panel can stop any/all NIJ Level IIIA ballistic threats (high-velocity 9mm Parabellum and .44 Magnum rounds) within this 2-3-layer envelope. One of the people we\’re going to try to reach about this is our friend and professional contact Mike Foreman at Point Blank Solutions, Inc. (PBS), who\’s apparently already familiar with the product. According to him, PBS already has two prototype body armor systems that utilize Kevlar XP. Point Blank Solutions is the parent company of Point Blank Body Armor, Inc.

According to Outhous, ballistic vests utilizing Kevlar XP should be available \”later this summer\”, and will cost roughly the same amount as current Kevlar-based vests ($400-$1,000). Kevlar XP may help strengthen Kevlar\’s position against competing high-end ballistic fibers, including aramid fibers like Twaron, which is madee by Teijin Aramid/Teijin Techno Products Limited (Japan), and polyethylene fibers like Dyneema, which is made by DSM Dyneema (Geleen, the Netherlands).

Since DuPont is a juggernaut company, and Kevlar is a well-established and proven product over many years, DefenseReview predicts that an improved Kevlar product like Kevlar XP will do very well in the marketplace, provided it lives up to the initial hype. Time will tell.
