What is ultra high molecular weight polyethylene used for?
What is ultra high molecular weight polyethylene used for?
UHMWPE is also used in the manufacture of hydraulic seals and bearings. It is best suited for medium mechanical duties in water, oil hydraulics, pneumatics, and unlubricated applications. It has a good abrasion resistance but is better suited to soft mating surfaces.
Is ultra high molecular weight polyethylene?
UHMW (ultra high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance. The versatility of polyethylene has made it a popular plastic for countless industrial applications that require durability, low friction, and chemical resistance.
What is UHMW film?
UHMW (ultra-high molecular weight polyethylene) has extremely high abrasion resistance, even exceeding that of steel. Slippery like PTFE but super abrasion and wear resistant, UHMW Polymers have a molecular weight average 10 times that of conventional high density polyethylene resins. …
How do you make ultra high molecular weight polyethylene?
Ultrahigh molecular weight polyethylene (UHMWPE) fibers are produced via a gel-spinning process in which a low-concentration solution of UHMWPE (M>2×106) is extruded to form a gel precursor fiber. This precursor fiber is subsequently heat-drawn to produce a very highly oriented molecular structure.
What is considered a high molecular weight?
There are three categories or types of High Molecular Weight (HMW, >10,000 daltons) polymers typically reviewed by the New Chemicals Program: Soluble, Insoluble/non-water absorbing (“non-swellable”), Water absorbing (“swellable”).
What temperature does polyethylene melt at?
122°C.
Linear low-density polyethylene (LLDPE) has a melting point of 122°C.
Which is the toughest ultra high molecular weight film?
UHMW Ultra High Molecular Weight Film is One of the toughest polyethylene classifications available. This type of polyethylene has a molecular weight number in the millions, which gives it its characteristic high degree of entanglement.
Which is ultra high molecular weight polyethylene ( UHMW )?
UHMW (ultra-high molecular weight polyethylene) has extremely high abrasion resistance, even exceeding that of steel. Coupled with broad chemical resistance and low coefficient of friction, UHMW is an extremely versatile engineering material for many severe duty service applications.
How is ultra high molecular weight polyethylene annealed?
When UHMWPE is annealed, the material is heated to 135 °C to 138 °C in an oven or a liquid bath of silicone oil or glycerine. The material is then cooled down at a rate of 5 °C/h to 65 °C or less. Finally, the material is wrapped in an insulating blanket for 24 hours to bring to room temperature.
What is the thickness of CS Hyde UHMW film?
CS Hyde Company offers UHMW film in a variety of thicknesses, from .003” (3mil) to .125” (125mil). Available with or without adhesive, in sheet, slit roll, and in custom and standard die-cut shapes.
