Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene ( HMPE ), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu . [ 1 ]
IPX 2000 ultra-high-molecular-weight polyethylene (IPX 2000, IPX UHMW, IPX UHMW-PE, IPX-UHMW-PE) is an engineered polyethylene compound developed to maintain many traits of UHMW, while increasing abrasion resistance, UV stability and decreasing friction and thermal expansion. [1]
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. ...
The material was developed by the Cuben Fiber and Cubic Tech Corporations in the 1990s. In 2015, Cubic Tech was acquired by DSM, their supplier for the UHMWPE fiber. The product was subsequently renamed "Dyneema Composite Fabric" ("DCF"), a generic brand name DSM uses for all of their composite products which incorporate UHMWPE. [3] [4]
Spectra Shield is a composite material (specifically, an ultra-high-molecular-weight polyethylene (UHMWPE) fiber) used in bulletproof vests and vehicle armour. It is manufactured by Honeywell . Spectra is a fiber offered by Honeywell, and "Shield" is their patented process for using resin [ 1 ] and a "plastic film" [ 2 ] to bind multiple ...
The high solvent retention allows for ultra-high drawing as with ultra high molecular weight polyethylene (UHMWPE) (e.g., Spectra ®) to produce fibers with a high degree of orientation, which increases fiber strength. The fibers are first cooled either with air or in a liquid bath to induce gelation, then the solvent is removed through ageing ...
Multifilament line, also referred to as The Super Lines, is a type of fishing line. [1] It is a braided line which is made up of ultra-high-molecular-weight polyethylene (UHMWPE), a specialty polyethylene polymer that makes an extremely thin line for its strength.
It is an extension of the double fisherman's knot and is recommended for tying slippery, stiff ultra-high-molecular-weight polyethylene (UHMWPE) and aramid cored ropes. [1] Tying the triple fisherman's knot is nearly identical to the double fisherman's, except for a third wrap before passing the end through each half of the knot.
