How strong is UHMW?
Differences Between HDPE and UHMW
| UNITS | UHMW-PE | |
|---|---|---|
| Tensile strength (73°F) | psi | 3,100 |
| Tensile elongation (73°F) | % | 350 |
| Flexural modulus of elasticity (73°F) | psi | 110,000 |
| Hardness Rockwell M&R, Durometer Shore D (73°F) | scale as noted | Shore D 64 |
What is stronger HDPE or UHMW?
This last property makes UHMW a preferred material for parts in sliding applications, those involving rough surfaces, or any situation where overcoming friction is important. HDPE (High Density Polyethylene) has a somewhat lower tensile strength than UHMW.
What is UHMW plastic sheet?
UHMW (ultra high molecular weight polyethylene) sheets are FDA approved, extremely impact-resistant, and a moisture-resistant material. They are resistant to shock and are durable, making them a popular material in a wide range of applications.
Does UHMW absorb water?
Yes, UHMW does not absorb water and is chemically inert.
Is UHMW a hard or soft plastic?
UHMW (ultra high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance.
How do you cut UHMW plastic?
If desired, you can cut UHMW using a band saw instead of a circular saw. When using a band saw, use a carbide-tipped blade with three teeth per inch.
How do I identify UHMW plastic?
The key difference between UHMW and HDPE is that UHMW contains long polymer chains with very high molecular weights whereas HDPE has a high strength-to-density ratio. UHMW stands for Ultra High Molecular Weight polyethylene. It is also denoted by UHMWPE.
Is UHMW plastic machinable?
Is UHMW machinable? Ultra-High-Molecular-Weight Polyethylene (UHMW) is a great material for machining. A hard plastic with a slippery surface, it is resistant to abrasion and wear, and allows for an extended equipment life which helps cut maintenance costs.
What is UHMW plastic made of?
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.
Is UHMW waterproof?
Ultra High Molecular Weight Polyethylene, or UHMW, is a thermoplastic with a high abrasion resistance and excellent waterproof capabilities that make it a favorite material in several industries.
Is UHMW stronger than steel?
UHMWPE consists of extremely long chains of polyethylene (PE). This means that UHMWPE fibres has an incredibly high tensile strength compared to many other thermoplastics, and this also means that the material is much stronger than steel in the fibre direction.
Does UHMW plastic float?
Self-lubricating – very low coefficient of friction (comparable to PTFE) Non-staining. FDA approved for use in food and medical applications. Low specific gravity – will float in water.
Where to buy UHMW plastic?

What is UHMW material?
UHMW stands for ultra high molecular weight polyethylene or UHMW-PE. Polyethylene materials are semi-crystalline materials with excellent chemical resistance, good fatigue and wear resistance, and a wide range of properties (due to differences in length of the polymer chain).
What is UHMW poly?
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.
What is UHMW polyethylene?
UHMW polyethylene is a prime candidate among a burgeoning group of designer polymers. The acronym in this tough plastic stands for Ultra-High Molecular Weight, a prefixing term that defines this form of polyethylene as a particularly dense subset of this popular thermoplastic.
