DSM Dyneema unveils Black Dyneema®
Black Dyneema is the latest result of DSM Dyneema bringing together its science, technology and engineering expertise in response to market needs that continue to change and develop.
Black Dyneema is similar to natural white Dyneema fiber, except that it is permanently colored throughout its cross-section. The coloring process has no effect on any of the key mechanical properties of the fiber, nor on its smooth surface. Very high breaking strength and stiffness, low density, low elongation, excellent durability, chemical, moisture and UV resistance are all retained, as is the fiber’s quality consistency.
Until now, Dyneema fiber has only been available in its natural white color. If users wanted to use the fiber in an application requiring color, they needed to post-treat it. But UHMWPE fibers are almost inert chemically, so the colors, which are only on the surface, tend to wear off.
DSM Dyneema expects Black Dyneema fiber to extend the use of Dyneema in existing applications, and to take it into totally new markets. There are some consumer applications where, although the mechanical and physical properties of natural colored Dyneema provide a perfect fit, aesthetic considerations limit its use. Possible examples where Black Dyneema might provide a compelling alternative include yachting lines, specific military applications, specialty ropes, nets and high performance sportswear. In addition, customers across diverse markets have already asked for a Black Dyneema fiber that can be combined with other, dark-colored materials.
The company also expects new applications to arise where the fiber needs to be invisible or nearly invisible. In areas such as fishing lines, for example, where Dyneema is already widely used, Black Dyneema will extend the market scope.
