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 .
The word is a portmanteau of the words thin and insulate, trademarked by 3M. [1] The material is made by the 3M Corporation and was first sold in 1979. [2] It was originally marketed as an inexpensive alternative to down; at the time, 3M claimed it was twice as warm as an equivalent amount of any natural material. [3] [4]

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.
polyethylene (PE), eventually with extremely long chains / HMPE (e.g. Dyneema or Spectra). Elastomers can even be used, e.g. spandex although urethane fibers are starting to replace spandex technology. polyurethane fiber; Elastolefin; Coextruded fibers have two distinct polymers forming the fiber, usually as a core-sheath or side by side.
Another fiber used to manufacture a bullet-resistant vest is Dyneema ultra-high-molecular-weight polyethylene. Originated in the Netherlands, Dyneema has an extremely high strength-to-weight ratio (a 1 mm (0.039 in) diameter rope of Dyneema can bear up to a 240 kg (530 lb) load), is light enough (low density) that it can float on water, and has ...
The Consumer Financial Protection Bureau (CFPB) on Wednesday warned that credit card companies devaluing or canceling reward points, cash back or miles rewards programs may be breaking the law.
