High Performance Plastics: Ertalyte vs. Delrin

ertalyte vs delrin

Plastic was first invented in 1907, and ever since then, it has become an extremely important type of material that is used in all sorts of different industries. It is now used to package foods, improve machine parts, and more. Without plastic, our world would be very different. What many people don’t know is that there are quite a lot of different types of plastics, especially high-performance plastics. Ertalyte vs Delrin is a debate that is hard to get through since these two types of plastics are both very good choices and have a variety of uses. But what is the difference between these two engineering plastics, and what should you know about them? Keep reading and learn more about it below.

What You Need To Know About Ertalyte

What is Ertalyte exactly, and how is it different from any other type of plastic? The first thing you should know about it is that it isn’t any ordinary type of plastic. This is due to the fact that it is crafted differently than most ordinary types of plastic.

In particular, it is considered a semi-crystalline thermoplastic polyester that has not been reinforced. It is mainly made from proprietary resin grades as well as polyethylene terephthalate (PET-P). All of this may sound very complicated and foreign, but all you really need to know about these terms is that they make the resulting plastic very durable and unique.

This is certainly not the type of plastic you’ll find at the grocery store or covering a package of food. Instead, you will often find this type of plastic in the engineering industry as well as inside machines and other situations. Due to its unique composition, it is resistant to a surprising number of different types of damage.  For one, it is quite resistant to acid. It also has plenty of dimensional stability as well as a low friction coefficient. Overall, it is extremely strong, which is why it is so often used in machine parts and other similar scenarios.

The Details

In particular, it is a great choice for close tolerance parts as well as any mechanical part that needs to support very heavy loads as well as a lot of endurance. Ertalyte plastic can handle all of this and more. Besides being resistant to acid, chemicals, and a variety of other things, it also has some other benefits that you might not expect.

For example, it does not absorb a lot of moisture which makes it perfect for environments that are often humid or otherwise moist. At the same time, it will also behave very well in dry environments. It is very resistant to abrasion and staining, and it is actually more resistant to acid than nylon.

The structure of this particular type of plastic is known to be very rigid. This makes the plastic very structurally strong, which is one of the reasons why it can support very heavy loads. This is not to mention that this type of plastic is also a great choice for high pressure or high-velocity scenarios. As you can see, Ertalyte plastic is extremely resilient and good for a great variety of things. But how does Delrin plastic compare?

What You Need To Know About Delrin

You might be wondering how Delrin can possibly compete with Ertalyte since Ertalyte seems so extremely durable. However, Delrin also has some unique benefits. This is due to the fact that Delrin is produced in quite a different way compared to Ertalyte. In particular, Delrin is made from acetal homopolymer. Because of this, it is quite similar to other types of acetal plastics on the market. Due to that fact, it also shares many of the same characteristics as other types of acetal plastics.

For example, this plastic is very resistant to abrasion, fatigue, and friction. It will withstand even the harshest of friction and abrasion environments without wearing down. Similar to Ertalyte, it has a very low moisture absorption level. For that reason, it is a good choice for environments that are rich with moisture as well as dry environments since moisture will not directly affect the plastic in any significant way. It has very good dimensional stability, much like Ertalyte.

The Benefits

At the same time, it also has very good electrical properties and is overall a very durable and reliable choice for a variety of industrial needs. This plastic has a crystalline structure which allows it to be stronger than most types of plastics. In particular, this structure renders it very rigid, so it is naturally very difficult to destroy its structure.

However, Delrin has one big downside: it is porous. It is porous due to its formation process which requires gas to escape, effectively creating very small holes throughout the entire piece of plastic. It is virtually impossible to prevent this from happening. The reason why this is a big downside is that its porous nature makes it more susceptible to bacterial growth. This can be an especially big problem if this type of plastic is used for medical tools. However, if the plastic is not used in the medical field, the porousness may not be too much of a problem.

Ertalyte vs Delrin

When it comes to Ertalyte vs Delrin, they are both very important high-performance plastics. They are both very strong because of how rigid they are, and they are both quite resistant to friction, abrasion, and moisture. Severna is able to manufacture both of these materials if you ever happen to need them.
