Dyneema is a strong fibre that is used in applications that range across sectors, as diverse as sports and leisure, aquaculture, and protective apparel.

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

Until now, Dyneema fibre has only been available in its natural white colour. If users wanted to use the fibre in an application requiring colour, they needed to post-treat it. But UHMWPE fibres are almost inert chemically, so the colours, which are only on the surface, tend to wear off.

Black Dyneema is similar to natural white Dyneema fibre, except that it is permanently coloured throughout its cross-section. The colouring process has no effect on any of the key mechanical properties of the fibre, the company reports.

Very high breaking strength and stiffness, low density, low elongation, excellent durability, chemical, moisture and UV resistance are all retained, according to the manufacturer.

New markets

DSM Dyneema expects Black Dyneema fibre to extend the use of Dyneema in existing applications, and to take it into totally new markets. There are some consumer applications where aesthetic considerations limit its use, the company reports.

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 fibre that can be combined with other, dark-coloured materials.

The company also expects new applications to arise where the fibre needs to be invisible or nearly invisible. In areas such as fishing lines, for example, where Dyneema is already widely used, Black Dyneema could extend the market scope.
