UHMWPE rope is less dense than water, making water recoveries easier as the recovery cable is easier to locate than wire rope. The bright colours available also aid with visibility should the rope become submerged or dirty. Another advantage in automotive applications is the reduced weight of UHMWPE rope over steel cables.
Dyneema Composite Fabric (DCF), also known as Cuben Fiber (CTF3), is a high-performance non-woven composite material used in high-strength, low-weight applications. It is constructed from a thin sheet of ultra-high-molecular-weight polyethylene ( UHMWPE , "Dyneema") laminated between two sheets of polyester .

UHMWPE is polyethylene with a molecular weight numbering in the millions, usually between 3.5 and 7.5 million amu. [25] The high molecular weight makes it a very tough material, but results in less efficient packing of the chains into the crystal structure as evidenced by densities of less than high-density polyethylene (for example, 0.930–0. ...
M5 has a tensile strength of 4 GPa [1] to 9.5GPa. [2] Other aramids- (such as Kevlar and Twaron) or UHMWPE-fibres (such as Dyneema and Spectra) range from 2.2 to 3.9 GPa. [3]M5 has "very high levels" of fire resistance, flame retardancy, and chemical resistance, especially high for an organic fiber.
In any event the article is wrong in my opinion on two counts (1) It promotes and is about a brand name and (2) Is factually incorrect since it implies/states that Dyneema is somehow "the technology", when in fact, UHMWPE is the technology, examples of which are Spectra and Dyneema and others....
Here's the short answer in the jump rope vs. running debate: They both really rock and for many reasons. Running is a full-body workout that boosts cardiovascular endurance, ...
Spectra is an ultra-high-molecular-weight polyethylene (UHMWPE) made by Honeywell, which offers superior UV resistance (on par with PET), very high initial modulus numbers (second only to high modulus Carbon Fiber), superior breaking strength, and high flex strength. However, it also exhibits permanent and continuous elongation under a ...
