Question: What Is The Difference Between UHMW And Uhmwpe?

What is the difference between UHMW and HDPE?

HDPE (high density polyethylene) is a durable, versatile, low-cost, abrasion- and chemical-resistant plastic material.

UHMW (ultra high molecular weight polyethylene) is an extremely tough, abrasion-resistant, low-cost plastic, used for a wide range of wear applications..

What is Uhmwpe 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.

Can UHMW be welded?

Yes, UHMW can be welded. Virgin UHMW is preferable but factory regrind is also weldable. Some UHMW with silicone and other additives is not weldable. Also some colors cannot be welded because of the types of pigments and dyes used.

How flexible is UHMW?

Ultra High Molecular Weight (UHMW) polyethylene is a semi-crystalline polymer that offers good abrasion and impact resistance plus a low coefficient of friction. It’s flexible enough to excel in both wet and dry environments with good wear and service life.

Is Uhmwpe bulletproof?

High Strength UHMWPE Ballistic Fabric 48″x65″ NIJ IIIA Capable. Ultra High Molecular Weight Polyethylene bullet proof fabric made of Spectra® fiber. 15 times stronger than steel, 40% stronger and 25% lighter than other Aramid fabric such as Kevlar. … Same material we use in our rifle panels that stops AK and AR rounds.

What’s the toughest plastic?

PolycarbonateStrength, durability and impact resistance Polycarbonate is the strongest plastic that is 200 times stronger than glass and is warranted against breakage or cracks.

Can you heat and bend UHMW?

Heat bending is not very good, it has a memory and will try to return to it. So if you do try heating bathe it in water to get even heat, I think 250-300 would do it. uhmw will go clear right before it goes blop.

How is Uhmwpe made?

3.1. 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.

Does UHMW float in water?

Non-staining. FDA approved for use in food and medical applications. Low specific gravity – will float in water.

Is Delrin and UHMW the same?

UHMW has surface and chemical properties that are rare to find in high-performance polymers. It is very resistant to most chemicals, UV radiation, and micro-organisms, but doesn’t have the same creep resistance as Delrin.

How do you cut a UHMW?

How to Cut UHMWUse a tape measure and mark the cut location with a pencil if the UHMW is a light color. … Install a 12- to 14-inch diameter carbide-tipped blade with 24 teeth into a table-mounted circular saw. … Place the piece of UHMW onto the work surface and align the pencil or chalk line in front of the circular saw blade.More items…•

What is Uhmwpe material?

Ultra high molecular weight polyethylene – Chemical Compound (UHMWPE) UHMWPE is a subset of the thermoplastic polyethylene. It has extremely long chains resulting in a very tough material, with high impact strength.

What does UHMW mean?

ultra high molecular weight polyethyleneUHMW (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.

How strong is UHMW?

Its high-density polyethylene resin has a molecular weight range of 3 to 6 million, compared to 300,000 to 500,000 for high molecular weight (HD-PE) resins. That difference is what ensures that this material is strong enough to withstand abrasion and impact better than lower level plastics.

Why is Uhmwpe suitable for a hip joint?

Highly cross-linked UHMWPE has recently become the alternative bearing material of choice in hip replacements, because it is relatively inexpensive and has biocompatible properties. It is an economical material alternative and offers design flexibility, including smaller sizes.
