Spectra® S-900 fiber was the first commercially available extended-chain, high-strength polyethylene fiber and the first in a series of Spectra fibers. It is available in multiple deniers (650 - 5600) for use in a wide range of applications.

Spectra® fiber has one of the highest strength to weight ratios of any manmade fiber. Its high tenacity makes it pound-for-pound 10 times stronger than steel, more durable than polyester and gives it a specific strength that is 40 percent greater than aramid fiber. Specific performance is dependent upon denier and filament counts.
