Who makes UHMW?
Lundell Plastics Corp.
Lundell Plastics Corp. Manufacturer of abrasion-resistant and food grade ultra high molecular weight (UHMW) polyethylene sheets. Available in full and partial sheets and 4 x 10 ft.
What is the difference between UHMW and UHMWPE?
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. The term HDPE stands for High Density Polyethylene.
What does UHMWPE stand for?
Ultra High Molecular Weight Polyethylene
UHMW-PE stands for Ultra High Molecular Weight Polyethylene. It is the highest quality polyethylene (PE) available, engineered for tough jobs and a wide range of applications. It delivers savings in a number of difficult applications. Ultra High Molecular Weight is the secret of this polymer’s unique properties.
What is UHMWPE material?
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.
How is UHMW manufactured?
UHMWPE powders have been produced by Ruhrchemie (Ticona) using the Ziegler process. The main ingredients for producing UHMWPE are ethylene (a reactive gas), hydrogen, and titanium tetra chloride (the catalyst). The polymerization takes place in a solvent used for mass and heat transfer.
What is reprocessed UHMW?
Reprocessed UHMW (Ultra High Molecular Weight Polyethylene) is a machinable thermoplastic that serves as an economical and environmentally friendly option for non-food applications.
What color is UHMWPE?
Gray
UHMW is an Ultra High Molecular Weight Polyethylene with a molecular weight between 5 and 9 million, making it by far one of the polymer materials with the highest molecular density….Lineup.
| Grade | Color | |
|---|---|---|
| UHMW-ASN | High Antistatic | Gray |
Is HDPE better than UHMW?
HDPE is used in a variety of applications and industries where impact resistance, high tensile strength, low moisture absorption and chemical and corrosion resistance properties are required. In terms of machining, HDPE finishes a little better than UHMW, although both materials machine well.
Can UHMWPE be extruded?
Both HDPE and PVC are commonly used for pipe extrusion because plastic pipes transport high-volume, high-velocity liquids more efficiently than concrete or metal. Both materials are lightweight with good resistance to chemical corrosion.
Is UHMWPE better than Kevlar?
Kevlar is generally more flexible than UHMWPE, and comes in many different qualities. This is also because many manufacturers buy the fiber and weave their own solution, which results in a wide range of qualities, as you can buy Chinese Kevlar spun body armor and European spun body armor.
Is Teflon a UHMW?
UHMW (Ultra High Molecular Weight Polyethylene) and PTFE Sheet (PolyTetraFlouroEthylene) are very similar materials, and yet very different at the same time. They both possess certain characteristics that make them similar to each other.
Does UHMW float in water?
Non-staining. FDA approved for use in food and medical applications. Low specific gravity – will float in water.
What is UHMW-PE resin?
Because UHMW-PE resin has a molecular weight range of 3-6 million, compared to 300,000-500,000 for high molecular weight resins like HDPE, UHMW-PE products withstand abrasion and impact much better than lower-level PE products, and even PTFE. Its high molecular weight also means it will not melt or flow as a molten liquid.
What is UHMW PE plastic molding?
UHMW-PE Plastic Molding UHMW-PE’s high molecular weight means it will not melt or flow as a molten liquid. Processing methods are therefore derived from those of powder metal technology. Compression molding is the most common conversion process used with this resin, producing a stronger, more consistent product.
Can UHMW-PE be transformed and molded?
UHMW-PE cannot be transformed and molded by conventional plastic processing techniques (injection molding, blow molding). Ultra High Molecular Weight polyethylene (UHMW-PE) is an engineering thermoplastic with a molecular weight of greater than 3.1 million AMUs (atomic mass units).
What is the difference between UHMW-PE and HDPE?
Less expensive than PTFE, it can offer significant savings in many high volume applications. Because UHMW-PE resin has a molecular weight range of 3-6 million, compared to 300,000-500,000 for high molecular weight resins like HDPE, UHMW-PE products withstand abrasion and impact much better than lower-level PE products, and even PTFE.
