2.5.7 Ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene (UHMWPE) belongs to the thermoplastic PE with a molecular mass usually between 2 and 6 million. As an extended chain PE fiber, it can produced by gel spinning, which yields a highly oriented fibrous structure with exceptionally high crystallinity (95–99%
UHMWPE is a linear polyolefin with a repeating unit of − CH 2 CH 2 −. Medical-grade UHMWPE has long chains with a molecular mass of 2 × 10 6 –6 × 10 6 g mol − 1 and is a semicrystalline polymer with a set of ordered regions embedded in a disordered amorphous phase ( Turell and Bellare, 2004 ). UHMWPE has low friction, high wear
UHMW molecular weight ranges from 3.1 million to 100 million grams per mole , with an ideal replacement for stainless steel in transporting difficult materials . UHMW -PE has crystalline melting point of 267F (131C). Recommended maximum service is about 200F (93C) Brief content visible, double tap to read full content.
received 13 December 1999. Abstract. Ultra high molecular weight polyethylene (UHMWPE) is a high performance polymer having low. efficient of friction, good abrasion resistance, good chemical
Ultra-high molecular weight polyethylene sheet has good wear resistance, impact resistance and self-lubricating properties, and is lighter in specific gravity, easy to use, moderately priced, and extremely cost-effective. Feature High wear resistance and impact resistance Self-lubricating, low friction Anti-aging and low temperature resistance
Ultra High Molecular Weight Polyethylene Sheets ( UHMWPE ) UHMWPE ( Ultra High Molecular Weight Poly Ethylene ) to solve friction, wear and material flow problems in many areas of industry. The material is distinguished for its outstanding sliding properties, extreme wear resistance, high impact strength and very high resistance to chemicals and has established itself in technical applications.
UHMW, also known as UHMW-PE (Ultra High Molecular Weight Polyethylene), is a semi-crystalline thermoplastic material, with a continuous use temperature range of up to 180° F (82° C). It is categorized as an engineering material, and offers a unique combination of wear and corrosion resistance, a low-friction surface, and high impact strength.

With over 70 locations across the United States, Mexico and Canada, Polymershapes has been at the forefront of plastic distribution, serving clients since the 1940s.
Ultra-High Molecular Weight Polyethylene (UHMWPE) was first polymerized in the 1950’s. The first UHMWPE fibers were commercialized in the late 1970’s. Composition UHMWPE is a type of polyolefin that is composed of very long chains of polyethylene with a very high percentage of parallel orientation and high level of crystallinity.
This Ultra High Molecular Weight (UHMW) Polyethylene will outwear all other materials, including metals, nylons, urethanes, and fluoroplastics. Applications include guide rails, wear plates, rollers, conveyor augers, bin and hopper lines, chutes, bearings, bushings, and gears. Exceptionally high abrasion & impact resistance; Low coefficient of friction
Product Description. The opaque black UHMW sheet has a standard tolerance. UHMW (ultra high molecular weight) polyethylene is an impact-, chemical-, and moisture-resistant plastic that has excellent abrasion resistance and a low-friction surface. UHMW is more rigid than LDPE and HDPE, and has better abrasion resistance than PTFE.

Ultra-high-molecular-weight polyethylene ( UHMWPE ), also known as high-modulus polyethylene ( HMPE) or high-performance polyethylene ( HPPE ), is a thermoplastic. It has extremely long chains, with molecular weight numbering in the millions, usually between 2 and 6 million. The longer chain serves to transfer load more effectively to the
high abrasion resistance, impact strength and low coefficient of friction. These special properties allow the product to be used in several high performance applications. UTEC is sold in powder form in grades that vary according to the molecular weight and the average particle size. The molecular weight may be in the low range (3 million g/mol
Product Introduction. High molecular weight polyethylene sheet has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals can cause chemical corrosion. The polymer is non-hygroscopic and has good water vapor resistance, and can be used for packaging purposes. HDPE sheet has good electrical properties
