Dyneema Solution Protects Navy Boats

25 March 2007

To realize the requisite flame retardancy for ballistic protective panels on Korean marine vessels, a solution was developed based on the addition of an aluminium and glass-epoxy resin layer to panels made with Dyneema HB25.

A patent application for this solution has been filed by DSM. This unique combination of flame retardant properties, excellent ballistic protection and durability in demanding environments, at the lowest weight possible is now available for marine and also for vehicle applications worldwide.

The new solution was developed in close cooperation with Samyang Comtech, manufacturer of boat armour panels for the South Korean Navy. “The weight of boat building materials is a critical factor in the design of these craft and the ballistic protection materials must therefore be as light as possible, while still delivering the high protection performance required,” commented Mr. Youk, Sang –Soon, Navy General Manager for Samyang. “Dyneema HB25 is the lightest ballistic protection material available and provides excellent bullet resistance. Now, the addition of flame retardant performance makes it the ideal material choice for us.”

Until now, boats had to use either steel, glass or ceramic armouring which meant lower ballistic protection and higher weight. Adding ASTM 1354-compliant flame retardancy to Dyneema HB25, an ultra strong composite material from DSM Dyneema, now means that all the strength and lightweight benefits of Dyneema can be applied to marine and vehicle armouring applications with the requisite flame retardant performance. This key development has made Dyneema HB25 the choice of the South Korean Navy for boat armour panels. The panels manufactured by Samyang will help protect the LSF-II hovercraft and PKX fast patrol boats from ballistic impact and fire, while significantly reducing overall weight.

“We are extremely excited about this key new development for the marine industry and delighted that we can deliver world-class lightweight and flame retardant protection to the Korean Navy,” said Josse Kunst, vice president Life Protection APAC, for DSM Dyneema. “Moreover, DSM Dyneema’s practice of close collaboration with our partners such as Samyang Chemical Co., Ltd., was a key factor in realizing our success in bringing innovative, high performance solutions to end customers.”

DSM has also acquired Pamako in Zurich from FMS Enterprises Migun Ltd. The acquisition includes Pamako's technology for the production of UHMWPE (Ultra High Molecular Weight Polyethylene) based products. DSM will further develop and improve this technology, and incorporate it in its existing business for Dyneema fiber and Dyneema UD (UniDirectional bullet resistant sheet).
