If you’re looking for a thermoplastic material that is durable and versatile, HDPE should be at the top of your list. We love HDPE because of its ability to resist environmental stressors and its versatility. From agriculture to construction, HDPE has found use in many industries so it’s no surprise that they barely last on our shelves. But, really let’s talk about what makes this material so special.
Chemical Properties
This thermoplastic is resistant to many acids, bases, and alcohols. This and its super high melting point add to its versatility and make it a great choice for insulators. For a corrosion-resistant material, it sure is affordable.
Physical Properties of HDPE
It’s not only the chemical properties that make HDPE durable. What happens when you combine high tensile strength, with a lightweight feature- you get durability and very high resistance to wear and tear. Compared to other plastic products, HDPE has a stiffer composition, so it may or may not last longer- you’re going to have to try it to find out.
Some Stand-Out benefits of HDPE’s physical properties;
- Impact resistance: HDPE absorbs shocks without breaking or cracking
- Stress cracking resistance: No pressure from outside can stress an HDPE sheet.
- Low friction: HDPE’s smooth surface has little to no friction, so you’ll find them being used for conveyor belts and sliding components.
- Electrical insulation: It is thick enough to be used as an insulator for wiring and electrical components
Making Use of HDPE
Many industries use HDPE for different functions, but these are some of the most common applications.
- Packaging: don’t forget that HDPE is shatter-resistant, not just strong. This is very useful for packaging because of all the movement that it can involve. The bottle of your favorite shampoo was probably made from HDPE.
- Gas Pipes: Corrosion resistance is cool must have property for gas pipes, and HDPE’s fit all the right descriptions of what an ideal gas pipe should be.
- Construction: HDPE is slowly kicking wood off the market- not completely but it is a great substitute for wood if you’re looking for more non-traditional aesthetic for your decks, fence, or outdoor furniture.
Overall, HDPE is a 10 out of 10 thermoplastic. If you’re considering it for your next project, you’re already on the right track.
