PE-HD or PE-UHMW: The Difference That Matters
When it comes to choosing a plastic material for various applications, it can sometimes be difficult to make the right choice. We offer a wide range of plastic materials, including PE-HD and PE-UHMW. But what is the difference between these two materials, and when should you choose one over the other?
One of the biggest differences between PE-HD and PE-UHMW is density. PE-HD has a density of around 0.95 g/cm³, while PE-UHMW has a density of around 0.93 g/cm³. This may seem like a small difference, but it can have significant implications in certain applications.
Density and Wear Resistance
PE-UHMW is known for its excellent wear resistance, thanks to its low density and high molecular weight. This makes it an excellent choice for applications where the material is subjected to high wear and tear, such as in conveyor belts and slide rails. PE-HD, on the other hand, has slightly lower wear resistance, but is still a very good choice for many applications.
But how big is the difference in wear resistance between PE-HD and PE-UHMW, really? Is it really worth choosing the more expensive PE-UHMW, or is PE-HD sufficient? This is a question we often get from our customers, and the answer depends on the application in question.
Machinability and Processing
Both PE-HD and PE-UHMW are easy to process and machine, but PE-HD is slightly easier to work with. This is because PE-HD has a slightly higher density and a lower molecular weight, making it more accessible to standard tools and machines. PE-UHMW, on the other hand, sometimes requires special tools and machines to be processed optimally.
But what happens if you choose PE-UHMW even though PE-HD would be sufficient? Will you encounter any problems with processing, or does it not matter? This is a question worth asking, as it can have significant implications for the final result.
FDA Approval and Food Contact
Both PE-HD and PE-UHMW are FDA-approved for food contact, making them excellent choices for applications in the food industry. PE-UHMW is, however, the better choice if you need a material that can withstand extreme temperatures and chemicals, such as in applications with direct contact with food.
But how important is it to choose an FDA-approved material, really? Is it really necessary, or can you choose a material that is not FDA-approved? This is a question that depends on the application in question and the requirements placed on the material.
Applications and Uses
PE-HD and PE-UHMW are both used in a variety of applications, but PE-UHMW is more common in applications where the material is subjected to high wear and tear, such as in:
- Cutting boards
- Conveyor belts
- Slide rails
PE-HD, on the other hand, is often used in applications where the material needs to have high chemical resistance, such as in:
- The food industry
- The chemical industry
- The pharmaceutical industry
But what happens if you choose PE-HD instead of PE-UHMW in an application where PE-UHMW would be the better choice? Will you encounter any problems, or does it not matter? This is a question worth asking, as it can have significant implications for the final result.
Summary and Conclusion
PE-HD and PE-UHMW are both excellent materials for different applications, but they have different properties and uses. PE-UHMW is known for its excellent wear resistance and chemical resistance, while PE-HD is a good choice for applications where the material needs to have high chemical resistance.
But how do you choose the right material for your application? This is a question we often get from our customers, and the answer depends on the application in question. We always recommend taking a look at the material properties and comparing them to the requirements of the application.
For example, PE-UHMW has a shore hardness of 65 Shore D, making it an excellent choice for applications where the material is subjected to high wear and tear. PE-HD, on the other hand, has a shore hardness of 60 Shore D, making it a good choice for applications where the material needs to have high chemical resistance.
