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. ...
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 ...
