DuPont Launches New Lightweight Helmet Innovation at Eurostary

Monday, June 11th, 2018

DuPont Safety & Construction will launch a new lightweight innovation for tactical helmets, DuPont™ Tensylon® HA120, at Eurosatory, June 11-15, 2018.

“DuPont™ Tensylon® HA120 is a new material for helmets that provides maximum ballistic protection at a lighter weight than traditional helmets, taking some of the load off the men and women on the front lines,” said John Richard, vice president and general manager, DuPont™ Kevlar® and Nomex®.

“Tensylon® HA120 enables helmets to be up to 40 percent lighter than traditional helmets allowing military and law enforcement members worldwide to stay safer and move faster with improved mobility.”

Designed with optimum ballistic properties and impact resistance, Tensylon® HA120 ensures maximum protection and lightweight durability for high performance helmet applications. Optimizing the performance of traditional Tensylon® solid state extruded ultra-high molecular weight polyethylene (UHMWPE) film technology, allows manufacturers to make lightweight ballistic helmets with superior protection from bullet penetration and low back face deflection (BFD), in a single-step processing cycle. To improve mold release, bonding to paint and abrasion resistance, a Tensylon® HA120 core can be co-molded with outer skins of woven fabrics made with Kevlar® fiber.

“Innovation is a continuous process at DuPont,” Richard said. “We’re constantly looking for new solutions that are stronger, lighter and more comfortable for the men and women protecting us. They deserve the best protection, so they can stay focused on the high-risk job of safeguarding their communities and their countries.”

The new Tensylon® HA120 material and other DuPont ballistics solutions will be featured at the DuPont Safety & Construction booth located in Hall 6, Stand J251 at Eurosatory 2018 at Parc des Expositions de Paris Nord Villepinte in Paris. Customers and the media also are invited to attend a DuPont Safety & Construction reception at the Le Chalet des lles restaurant, Wednesday, June 13, 2018, at 7:30 p.m. CEST.

Blast From The Past – SSD Visits DuPont

Wednesday, August 26th, 2015

SSD made this visit to DuPont back in August of 2010. The post offers a great look at the advantages of FR materials.

DuPont’s Spruance facility in Richmond, Virginia recently hosted SSD for an in depth look at Fire Resistance and Ballistic Protection.

Back in the 60s a new class of fabrics was developed, called Aramids with DuPont at the forefront of their creation. Two fabrics in this class have become the cornerstones of modern Soldier Survivability; Kevlar and Nomex. They provide Ballistic and Fire protection respectively. Kevlar was initially developed by DuPont for tire belts but not put to its current use until the early 70s. Nomex on the other hand was quickly integrated into flying and space suits not long after its creation.

The most compelling portion of the visit was the ThermoMan lab. Composed of 122 sensors, ThermoMan was designed with the assistance of NC State. In addition to the mannequin, there is also a skin burn injury model that takes data collected at the sensors and displays how a thermal threat would equate to an injury to the human body. One interesting aspect of the ThermoMan over other testing methods such as the commonly used vertical flame test is that the ThermoMan tests not only the material’s performance but also the garment’s overall design and construction. This is a critical factor in protecting a wearer from thermal threats. If a flame can get inside a garment then the wearer might as well not be wearing FR at all. Interestingly, the pocket configuration of the issue flight suit is designed to provide additional protection for the wearer by doubling the layers of Nomex in certain key areas. Testing has revealed that most injuries actually occur after the flame threat is removed and the wearer is subjected to residual heat retained by the garment.

We witnessed two burns consisting of a 3 second burn delivering 6 calories. It is intended to replicate a JP4 fire. In the first burn, an issue CWU-27/P US issue flight suit manufactured from Nomex III.

As you can see, minimal damage was sustained by the ThermoMan due to the material and design of the flight suit. it is important to note that while the ThermoMan does a great job predicting injuries, actual injuries may vary due to a wearers body and the fit of the garment. Experience has shown that 1% injury equates to 1 day in the hospital. In this case, the ThermoMan indicated 7% injuries.

In the second, a similar looking flight suit manufactured from 65/35 PolyCotton was subjected to the same threat. PolyCotton, a mixture of 65% Polyester and 35% Cotton is commonly found in Chinese made garments. There IS a place for this fabric, but as you will see in the video, it isn’t in a flame threat environment. Rather, PolyCotton is a cool fabric and very good for use in warm climates. The choice of materials goes back to our recent article concerning knowing your equipment, the threat, and environmental conditions and making an informed choice about which equipment to choose. As you can see the PolyCotton not only caught on fire but it continued to burn even after a direct flame was removed. In this case, the ThermoMan sustained 75% injuries.

During our visit to the ballistics lab we witnessed a demonstration of testing of an armor vest and were introduced to the various apparatus used during testing. Additionally, we were given the opportunity to try out first hand correctional armor which is designed to stop stab and puncture threats. We were amazed at how much differently ballistic and correctional armor reacted to the icepick type of shiv commonly found in correctional facilities. The bottom line is that correctional armor works.

We were fortunate enough to be able to discuss a variety of current Soldier Systems issues with the DuPont team but probably the most important message we got was that DuPont is constantly looking at new ways to use their flagship products. Adaptability is the key as they not work to improve the performance of their materials but also as they seek new ways to use their products as well as combine them with other fibers.

While in years past many vendors would have pushed monolithic solutions to threats, it makes more sense now to develop hybrid solutions that combine multiple fibers into a more robust material. This way, the best characteristics of different materials can be combined into a common solution.

Overall, the meeting was excellent and we left with a greater appreciation of the level of commitment DuPont has to protecting our troops and public safety professionals.

Kevlar Inventor Stephanie L Kwolek Passes Away

Sunday, June 22nd, 2014

20140622-095852-35932936.jpg
We all have much to owe Stephanie L Kwolek, who invented the basic Kevlar compound while working for DuPont in 1964. Amazingly, she was attempting to develop a material to replace steel radial belts in tires when a polymer she was working didn’t quite come out right. On a hunch, she had it spun into fiber that turned out to be five times as strong as steel as well fire resistant. Further development resulted in the Kevlar family of aramids we know today, although it took a decade for the material to be introduced into soft body armor. Eventually, Ms Kwolek was honored with a National Medal of Technology in 1996 for her work that has resulted in countless lives saved.

20140622-100631-36391744.jpg

DuPont continues to develop the material discovered by Ms Kwolek. Just last week, they announced that the millionth vest made from Kevlar XP had been manufactured and they recently launched DuPont Kevlar AS450X, specifically engineered for greater comfort to the body armour wearer while protecting against multiple threats including bullets, knives, spikes, bullets and blunt objects as well as DuPont Kevlar XP S104, a water repellent fabric that offers enhanced bullet stopping power and reduced back face deformation, even in hot and humid climates and wet conditions.

Born on July 31, 1923, in New Kensington, Pennsylvania, Stephanie L Kwolek passed away in Wilmington, Delaware, on 18 June, 2014 at the age of 90.

Thank you for your hard work. Rest In Peace.

Ansell Collaborates with DuPont to Make New Ultra-Lightweight Gloves

Wednesday, September 19th, 2012

DuPont and Ansell, world leaders in protection technologies, have collaborated on Ansell’s newest ultra-lightweight and highly cut-resistant gloves to protect workers. The gloves, which feature DuPont Kevlar yarns and Kevlar in combination with reinforced stainless steel, are part of Ansell’s ActivArmr portfolio.

Ansell’s range of new products include an 18-gauge lightweight cut-resistant glove, hybrid cut-resistant padded protection gloves and ergonomic durable general purpose gloves that will revolutionize the way gloves are viewed. Ansell’s new “Best In Class” gloves are available globally for construction workers and are specifically suited for specialty trade, such as the HVAC, plumbing, heavy labor sectors and general contractors. Other gloves in the portfolio are targeted specifically for use by the military.

“The uses of DuPont Kevlar continue to grow in new, innovative ways. Our collaboration with Ansell is a great example of how Kevlar® can be spun with other materials to make another series of superior products to better protect people around the world,” said Thomas G. Powell, president, DuPont Protection Technologies. “This collaboration combined DuPont’s fiber and yarn technology with Ansell’s innovative glove design, tailored for specific applications. In this case, we developed a new manufacturing process to specifically produce ultra-lightweight steel-containing yarn, used in concert with our decades of experience in nylon, spandex and Kevlar fibers.”

Leveraging Ansell’s more than 100 years of industry expertise and innovation in protective gloves, DuPont’s decades of experience in fiber and yarn technology and DuPont patents in cut protection, the Ansell ultra-lightweight gloves are made with the latest technologies. They enable increased dexterity, flexibility, a closer sense of touch, stretch recovery and comfort without compromising safety, which is critical for workers who depend on the cut-protection of Kevlar. Using combinations of Kevlar, stainless steel, spandex and nylon, the new ActivArmr gloves boast Intercept Technology® in a thin, 18-gauge design that is significantly lighter weight than the traditional 13-gauge version. Intercept Technology using DuPont Kevlar Stretch Armor was created using a unique combination of Kevlar fiber and Ansell technology to deliver comfort, dexterity and high cut-resistance.

“Innovation and superior protection are the hallmark of Ansell’s hand protection solutions, including our ActivArmr portfolio. We understand that workers in each sector face unique challenges to hand protection, and so each Ansell glove design is backed by months of end-user testing to determine the specific features workers need to protect their hands without compromising productivity,” said Thomas Draskovics, president and general manager, Ansell Specialty Markets. “With DuPont, we have developed a unique application of DuPont Kevlar for our ActivArmr gloves that workers across construction sectors can trust to deliver superior protection, comfort and dexterity.”

According to a recent U.S. Department of Labor study, injuries to fingers and hands rank highest in workplace accidents (at 27 percent), and hand and finger accidents rank No. 1 in preventable injuries. A recent Occupational Safety and Health Administration (OSHA) study stated that more than 70 percent of arm and hand injuries could have been prevented with personal protection equipment (PPE), specifically safety gloves. DuPont and Ansell estimate the global construction market for gloves at more than $800 million annually.
